About Metal-Aid

Thousands of sites across Europe are polluted with toxic metals and organic solvents; many more exist worldwide.As EU population grows, clean water will determine the quality of life and economic stability. Most sites remain contaminated because existing technology is costly and disruptive. Society needs an innovative way to decontaminate soil and groundwater directly underground.

In METAL-AID, we will develop new technologies through fundamental knowledge. We are a partnership of 6 universities, 4 consulting companies and a government agency, from Denmark, Germany, Britain, Spain and Iceland. Our goal is to develop a new method for remediating contaminated soil and groundwater, in situ, so the activities on the land surface, such as houses, schools and businesses are not disturbed.

Active Field Sites


The target contaminant types are organic solvents and heavy metals. Research will investigate currently available products and develop new ones, characterise their physical and chemical properties and behaviour, test their effectiveness in laboratory, column and field experiments, compare their behaviour with natural analogues and inject them into a contaminated site and monitor their effectiveness.

Approaches for gathering data will include high tech techniques that can "see" at the nanometre scale, macroscopic experiments, molecular modelling, thermodynamic, kinetic and fluid flow experiments and modelling, field site characterisation, pilot scale injection studies and monitoring of the effectiveness of the reacting material over time.

The senior scientists and engineers and their teams, that will serve as hosts for the PhD fellows, are experts in their fields and the laboratory and field equipment to be deployed is state of the art, including instruments and techniques that have been designed and built by project partners.

The overall aim of the European Commission's ITN projects is to train early stage researchers (ESRs) to provide a highly competent workforce for the future of the European Union. Through hands-on activities, with experts at the host organisation, and the opportunity for secondments with other project partners, the Metal-Aid project will train: 14 PhD FellowsFor individual research tasks that are linked together to contribute to the general, overall project goals.

To meet the METAL-AID goals, the ESRs will:
1)Test known layered double hydroxide (LDH) and redox active green rust (GR) reactants that show promise forremediating toxic metals and chlorinated compounds and invent new ones;
2) Derive thermodynamic and kineticdata, essential for safety assessment modelling;
3) Quantify reactant effectiveness and reacted phase stability andcompare these with natural analogues;
4) Inject the new reactants at field sites operated by our beneficiaries.

New technology


LDH and GR interaction


METAL-AID begins at technology readiness level, TRL 1 and runs to TRL 6, implementation. The government agency will provide guidance so our new technology complies with regulations and has promised R&D funding after the ETN ends, to carry it into full commercialisation. The ESRs will be trained to tackle challenges of concern to society, to communicate across sector boundaries and with the public, in a network that will last long after the project ends. We will provide a pool of scientists for roles in EU's knowledge based economy.


METAL-AID  involves 11 different beneficiaries throughout Europe. For more information about the network, please see below.

Top level METAL-AID communication with the European Commission is handled by the Executive Body (EB), which includes Project Coordinator Dominique Tobler (KU), Academic Deputy Coordinators Eric H. Oelkers (UCL) and Liane G. Benning (GFZ) and Coordinators from two main non-academic partners. The Project Manager assists the coordinator in all aspects of the project.

Management meetings are held at network-wide training events and the minutes from the meetings are posted here.

Seventh Metal-Aid Management Meeting: Ronda, Spain, 3 June 2019

The meeting began with a discussion of ESR employment contracts and expected end dates for the ESRs. While most of the ESRs will finish their contracts within the originally defined recruitment dates, some have been on sick leave and will therefore finish a bit later. Because ESR 4 was on extended sick leave, it was suggested that the coordinator would contact the project officer to request an extension of the original project end date. This would allow ESR 4 to implement the full 36 months of his employment contract and would also allow ESR 5 at UCL to complete her 36 months. If the project officer accepts the extension, this would delay submission of the final reports and would also consequently delay the final payment. The project was originally scheduled to end on June 30, 2020 and would instead end in January 2021. As the total budget for the project is based on all 15 ESRs completing 36 month contracts, the research training budget and management and overheads budget held back at KU would decrease if all months are not implemented. If any host institutes have money remaining in their local research training budgets or management and overheads budget and if local rules allow, it is possible to use this remaining money to pay for some extra months of employment for the ESR or to use this money to continue to cover ESR expenses even after the EC employment contract has ended.

PIs and ESRs were next reminded about the need for discussion of local requirements for defending a PhD. In some countries, the PhD thesis must include a specific number of publications, in others it is possible to provide a manuscript with a defined number of chapters, etc. For the ESRs to defend their PhDs, they must determine the exact specifications in their host counties and also reflect on a realistic timeline for the preparation, writing and submission of their PhD thesis prior to their defence.

The meeting next moved to a discussion of secondments. While most ESRs have completed their originally defined secondments, there are some who have not yet sent information about their secondments to Clare or for whom the information has not been updated on the portal. Both PIs and ESRs were reminded of the obligation to request approval for changes to secondments from the project officer.

At the beginning of the Metal-Aid project, it was agreed that a portion of the research training budget would be retained at KU to cover the costs of network events. There will be some money remaining in this budget even after the final network meeting. As the group plans to hold a field injection during the final network event, it was agreed that some of the remaining budget could be used to increase the size of the injection and that redistribution of remaining money would be revisited after the final network meeting.

PIs and ESRs were reminded about the obligation for all peer reviewed publications to be open access and that any embargo periods must have expired BEFORE the end of the Metal-Aid project. A list of upcoming deliverables with the lead institution for each deliverable was also provided. It is important to upload these deliverables to the portal in a timely manner.

Once the final Metal-Aid network meeting takes place, all of the training originally defined in the grant agreement will have been offered to the group. While the group has already participated in a large-scale outreach activity (in Iceland in September 2018), the coordinator proposed that another outreach activity could be associated with the final injection. One suggestion was to film the ESRs talking about their research projects and putting the videos online.

The meeting concluded with a discussion of remaining contractual obligations including updated career plans for each of the ESRs, meeting milestones and deliverables, updating the Metal-Aid website, the participant portal and completing final financial and progress reports for the European Commission.

Sixth Metal-Aid management meeting: Reykjavik, Iceland, September 11, 2018

The sixth Metal-Aid management meeting was held during the International Carbon Conference 2018  large scale outreach event whch brought together 5 different networks.  While the ESRs were receiving field training, the PIs met to discuss the recently submitted periodic report and progress to date across the network.

The meeting opened with a discussion about the periodic report and the upcoming interim payment from the European Commission.  Beneficiaries asked for more details about the  various payments sent by the European Commission and when they are received.  Beneficiaries were reminded about the deliverables due to the commission and the group revisited the list of deliverables and milestones defined in the grant agreement to ensure that progress was on target to reach all the originlly defined objectives.  The group also discussed the situation with ESR 4, currently on sick leave, and how this impacts the project.

The discussion next moved to a planning session for the remaining training courses and network events to be offered to the ESRs.  By the end of the project, all training promised will have been delivered.  Beneficiaries were asked to remind their ESRs to continue with their outreach efforts and to acknowledge EC funding on all publications.

The meeting concluded with a discussion of the final injection phase of Metal-Aid.  It was suggested that this could be combined with an outreach event.  Possibilities for various types of injections were discussed with injections likely to take place in Spring 2019.

At this point, the group broke into smaller subsets to discuss progress to date in each of the work packages.

Fifth Metal-Aid management meeting:   Giardini Naxos, Sicily, May 7, 2018

This Metal-Aid management meeting concentrated on preparation of the periodic report to be submitted to the European Commission at the end of the first reporting period on August 31, 2018.  Malene Roost Lytsen from the European Office at KU gave a presentation to all beneficiaries about how to prepare the financial reports on the participant portal including how to set up an FSIGN for those beneficiaries who have not yet done so.  She also reviewed the various budget categories and the types of documentation to be kept to justify spending in each category.  Malene's presentation was distributed to all beneficiaries.

Fourth Metal-Aid management meeting:   Kaprun, Austria, November 27, 2017

The management meeting opened with a review of training courses offered at network events to date and their associated costs. Much of the promised training has already been provided to the ESRs and they were encouraged to send any specific requests for future training events to Clare. The coordinator asked the ESRs if they would be interested in a career training event involving mock interviews for positions in both academia and industry and the response was positive to this proposal. PI Fidel Grandia from Amphos 21 provided information about a training course in 1D modelling to the ESRs. This course will take place in the spring of 2018 in Italy and Fidel will send the information to Clare for posting to the website. Approximately one third of the budget originally allocated for network wide training events has been consumed to date. The next planned training event will take place in Taormina, Sicily in May 2018 and will be associated with the Metal-Aid mid-term review.

Following the mid-term review, the Metal-Aid network will participate in a large scale international outreach event in Iceland in September 2018. This event will bring together a minimum of four networks, will be open to the general public and will provide opportunities for the ESR to present their work to both specialists and non-specialists. The tentative title for the meeting is “Science for a cleaner environment.” In addition to participation in the outreach event, ESRs will have the opportunity to take part in a training course in sampling techniques. Clare raised the question of how many network events to organise after the event in Iceland, but it was agreed to revisit this issue later when we have a better idea of how the research projects are progressing and where and when injections will take place in the field.

After a discussion of the network event budget including a question and answer session, Clare provided some reminders to the ESRs about their obligations. These included: - Carrying out their originally planned secondments or contacting Clare with any proposed changes so that she can request permission from the project officer - Writing a paragraph about their experience on secondment for posting to the project website - Continuing to engage in outreach activities with the general public and documenting these events through photos and information to be sent to Clare for posting to the project website
- Complying with the obligation to make any peer reviewed publications open access and acknowledging European funding on all publications
- Providing specific information to Clare on progress reports re. titles, dois, page numbers etc for any publications produced
- Requesting permission from their supervisors BEFORE registering for non-network training courses
- Getting in touch with the project manager and/or project coordinator should the ESRs wish to discuss any concerns or problems they encounter at their host/secondment institutes.

ESRs and PIs were also encouraged to send Clare information about any training events or conferences of potential interest to the group to be posted to the project website. Clare next presented some slides about the mid-term review. She provided information on what to expect:
- When and where the event will take place - who will attend from the European commission and from the network
- what ESRs will present and how they should prepare
- the general agenda for the two half days
- the mid-term report to be submitted one month prior to the event

To facilitate preparation of the mid-term report, Clare will modify the network progress report template to include a section for PIs to provide feedback on individual project progress and to ask both ESRs and PIs to tie their projects to the bigger picture behind the Metal-Aid network. The next network progress report should be returned to Clare by March 1 at the latest to allow time to prepare the mid-term report.

The meeting concluded with an open forum for questions and discussion.

Third Metal-Aid management meeting: Copenhagen, Denmark.  May 15, 2017

The third Metal-Aid management meeting was held during the network event which took place in Copenhagen from May 14-19, 2017. The theme of the network event was “Field methods and their applications, an industry perspective on the Metal-Aid project.” The meeting started with a discussion of project finances including a reminder about how the costs of network events are handled by the University of Copenhagen. A portion of the original Research Training allowance was held back at University of Copenhagen and is used to cover the costs of accommodations and subsistence for the beneficiaries at network events. When external participants attend, their costs are invoiced directly to their host institutes.

A question was next raised about the costs of sending fellows on secondment. All PIs and ESRs were reminded that secondments are an integral part of the fellows’ research experience and that it is obligatory for all ESRs to spend time on secondment. While on secondment, costs of accommodations and transportation to the secondary host institute are covered by the primary host. However, subsistence is covered by the fellows themselves. In the event that there are exceptional costs raised while a fellow is on secondment (i.e. extremely expensive analyses, for example), an agreement should be made between the primary host and the secondary host before the fellow goes on secondment to agree on how these costs should be covered. All fellows and PIs were also reminded that a good research plan for the intended secondment needs to be established between the involved parties in good time before the student embarks on a secondment, to ensure maximum outcome. Following the secondment, the students should write a short paragraph about their secondment experience to be posted to the project website.

The project manager, Clare Desplats, next reminded beneficiaries about the first progress report due to the European Commission this summer. She explained the various parts of the report: general progress of the action, recruitment strategy, career development plans for each researcher, management, communication and impact of the action. All beneficiaries were asked to confirm the number of applications received at their institute for each ESR position. ESRs were reminded that the information that they provide in their bi-annual progress reports will serve to complete the progress report submitted on the participant portal.

The meeting next moved to a discussion of the mid-term review. The project manager reminded everyone that the mid-term review is a contractual obligation and should be attended by all ESRs and PIs. It was agreed that the mid-term review should take place approximately six months after the next network event to be held in Austria in November 2017. This would mean that the mid-term review would be scheduled at around month 22 or month 23 of the project. Clare will set up a doodle poll to check availability of all PIs and will then contact the project officer to ask if the dates and location are also convenient for the REA.

The group next reviewed the list of deliverables defined in the Grant Agreement, particularly those related to training of the ESRs. So far the project is well on track to meet the original milestones and deliverables, but there are still two ESR positions open which should be filled before the end of the first year. ESRs have started to engage in public outreach activities and these are regularly posted to the website by the project manager. All beneficiaries were reminded about the obligation to make any peer reviewed publications accessible via Open Access.  This portion of the meeting served as the annual self-evaluation of the project.

The meeting concluded with an open discussion

Second Metal-Aid management meeting: Madeira, Portugal. November 30, 2016

The Metal-Aid management meeting was open to all PIs and ESRs and began with a review of contractual obligations as defined in the Grant Agreement. Beneficiaries were reminded that they must submit researcher declarations for their recruited fellows within 20 days of the start date of the ESR employment contract. Some beneficiaries have already done this whereas others have not because their fellows have either just started or will start in the following months. Beneficiaries were asked to provide personal email addresses for the fellows to facilitate contact with the European Commission after their employment contracts have ended. The project manager, Clare Desplats, has sent a copy of the Grant Agreement to all recruited fellows. ESRs were also informed that they must complete a Personal Career Development plan which will be returned to the project manager and forwarded to the Metal-Aid project officer.

The meeting next moved to a discussion of project finances. In order to negotiate better rates for group bookings for network events, a portion of the Research Training budget was held back at University of Copenhagen. This budget will be used to cover the costs of accommodations and subsistence for PIs and ESRs during Metal-Aid network events. In the event that external participants attend network events, they will be invoiced for their participation after the event. Clare answered questions from the beneficiaries about the various budget categories (Living, Mobility, Research Training and Management +Overheads) including how to report spending in non-euro currencies. All beneficiaries were reminded that the first financial report for the project will be due after month 24 (July 2018). The European Office at University of Copenhagen and the project manager will provide assistance to the beneficiaries for completing the financial reports.

After reviewing project finances, the meeting next addressed the H2020 obligation of Open Access for peer reviewed publications. In FP7 projects, Open Access was recommended but in H2020 it has become an obligation so both ESRs and PIs were made aware of this change. ESRs and PIs were also encouraged to document collaboration across the network via joint publications. All participants were reminded about the need to acknowledge EC funding on any publications produced by the network. The project manager has sent everyone the sentence to be used for acknowledgements.

Beneficiaries and ESRs were also reminded about the contractual obligation to spend time on secondment and to perform public outreach activities. Both secondments and public outreach activities will be documented by the project manager on the dedicated Metal-Aid website. All participants were also reminded that their attendance is obligatory at the mid-term review. The latest possible date for the review is August 2018 but it was agreed that the review would probably take place a little earlier to avoid conflict with other conferences which take place at that time (i.e. Goldschmidt 2018). There were questions from the PIs and ESRs about what typically happens at the mid-term review.

In order to document the training, research, secondment and outreach activities being done by the ESRs, it was agreed that the project manager would develop a progress report template to be completed semi-annually by the ESRs and signed by their supervisors. These reports will also be used by the project manager and project coordinator to complete the annual progress reports to be submitted to the European Commission via the participant portal. All participants agreed that future management meetings will be a good opportunity to review the contractual obligations of the various network participants to ensure that all milestones and deliverables are met. Participants also discussed how these deliverables and milestones should be reported. The meeting concluded with an open question and answer session including questions about dates and locations for future network meetings.

First Metal-Aid management meeting: Copenhagen, Denmark.  April 6 and 7, 2016.

The first Metal-Aid management meeting was held on April 6 and 7 2016 at the Nanoscience Center of University of Copenhagen to introduce all beneficiaries to the guidelines governing Marie Sklodowska Curie Actions Innovative Training Networks.  The meeting was attended by both administrative and financial staff from the beneficiary institutes and scientific supervisors.

The meeting commenced with a description of the project consortium, an explanation of MSCA ITN projects, the number of fellows to be recruited, the official start and end dates of the project and the reports to be provided over the course of the project. Following a question and answer session, the meeting then moved to a detailed explanation of finances, covering all budget categories: Living, Mobility, Research Training and Management and Overheads.  Differences between FP7 and H2020 ITNs were highlighted and information about how to report finances on the participant portal was provided.  Information was also provided on local and national contact points for queries related to Marie Curie projects.  The financial presentation concluded with an explanation of the percentage of pre-financing received for the Metal-Aid ITN and the typical payment cycle for these projects.  This portion of the meeting was also followed by a question and answer session.

After reviewing project finances, the meeting then moved to an explanation of the recruitment strategy to be implemented for the Metal-Aid project.  Under H2020, the European commission has strongly emphasized the need for merit based, transparent recruitment policies.  A checklist produced by the European commission was provided to all present and was reviewed by the group.  A discussion then ensued about the best way to advertise the positions (i.e. a group advertisement on Euraxess.  It was agreed that all beneficiaries would produce individual job ads for their ESR positions and that links to these ads would be uploaded as soon as possible to a dedicated project website.  Next, participants were reminded about signficant points to be included on employment contracts with the newly recruited fellows and the obligation to fill in a declaration on the conformity on the participant portal within 20 days of the start date of the fellow's contract.  This portion of the meeting concluded with a question and answer session.

The meeting next moved to a discussion of the obligations of Marie Curie fellows to spend time on secondment and to perform outreach activities targeting the general public.  Beneficiaries were asked to remind fellows to acknowledge EC funding on any publications, posters, etc produced during their fellowships.  It was suggested that the fellows create a project logo during the first network meeting to encourage them to work together and to give them a sense of ownership in the network.  Next, copies of the original annex to the grant agreement were distributed to the partners and the beneficiaries reviewed together the various deliverables promised to the European Commission.  The group discussed possible dates and locations for the first network meeting to be held with all PIs and newly recruited ESRs and a tentative date of end of November 2016 was retained but will be revisited once all partners have a better idea of when their ESRs will officially start their projects.

Research interests I get excited about topics related to environmental remediation processes using environmentally sound nano-materials. This interest of mine is drawn on previous research stints in Italy and Switzerland focusing on photocatalysis. As an experimentalist, I play on different synthesis parameters - inspired from out-of-the-box thinking, to improve the desirability of field-scale application. Furthermore, I am interested in finding answers to the fundamental behaviour of synthesized nano-materials through different characterization techniques

Research interests Green rusts have the potential ability to uptake and remove contaminant elements from water. Their layered structure and composition, containing both iron (II) and iron (III), are the essential cause of its high reactivity. Redox potential can be used to reduce toxic trace metals such as Cr(VI) or As(V). Furthermore, as it precipitates from aqueous solution, Fe(II) cations might be exchanged with other divalent cations, such as Mg2+, Cd2+ and Ni2+. This remarkable features makes green rusts a potential “trap” for polluting metals. My aim is to get a better understanding of how these processes occur in nature and how we could take advantage of them.

Research interests Through computation, we may have a deeper understanding of mechanisms of chemical reactions. The combination of computation and experiment becomes more effective and attractive to investigate chemical reactions. My main work is using DFT methods to explain and verify the results obtained from experiments, to provide experimental ESRs with new ideas and guidance such as studying reaction mechanisms of injection materials (like layered double hydroxides and green rust) and contaminants, designing different reactions by changing the molecular structures, and designing new materials by modeling and calculation.

Research interests In general, I seek to promote the responsible and sustainable use of our natural resources, which includes remediation of contaminated sites and ensuring clean water supply. Having worked on an acid mine drainage site and having investigated the mineralogy and geochemical interrelations of a heavy metal [high field strength element (REE,Y, Zr, Nb, Ti, Th)] deposit during my studies, I am most interested in the (aqueous) geochemistry and mobility of heavy metals, fluid-mineral interactions, and phase transformation reactions. Therefore, with my research within this project focusing on experimental investigations on contaminant reduction, I aim to gain a detailed understanding of the geochemical behavior and reaction kinetics of the pollutants under green rust-based remediation in contaminated soils and waters.

Fieke Mulders ESR 6: Fieke Mulders
Home country: Netherlands

Host institute:
University College London
Gower Street

United Kingdom
Research interests Over the last years, I have become especially interested in the kinetics and thermodynamics driving reactions at the solid-liquid interface. I find these processes interesting because I feel they can provide us with an insight on why fluid-solid interactions take place in the first place. For me the challenge lies in linking these nanoscale processes to the behaviour of pollutants/compounds at a larger scale. Understanding the nature of liquid-fluid interaction allows for a better prediction on how pollutants/compounds move within the natural environment, making it a socially relevant research topic.

Research interests My interests are focused on laboratory synthesis as well as chemical and mineralogical investigations and characterization of artificial and natural compounds, particularly of layered double hydroxides. Especially interdisciplinary topics with practical applications are of interest for me. Therefore I have passed a work experience in the Helmholtz Centre for Environmental Research Leipzig (UfZ) on the subject of degradation of organic pollutants and heavy metals. I am also familiar with modelling of chemical reactions using PhreeqC.

Tobias Linke ESR 12: Markus Reischer
Home country: Austria

Host institute:
Sortemosevej 19
3450 Allrød
Research interests My personal research interest includes generally the wide field of hydrogeology. In detail I’m interested in the hydro-chemical processes on field scale. As I was confronted with arsenic, antimony and tetrachlorethen in groundwater in the context of my Master’s thesis and my work, I have some questions about their occurrence. This includes questions about the source of contaminants, processes/reactions during transport and about possible remediation techniques. In this work I will focus on the development of a new in-situ remediation technique using green rust and how this method will work in a natural environment in combination with a detailed investigation of the test site.

Research interests I am interested in natural processes in environmental compartments and their interfaces. Besides mitigating anthropogenic pressures on these, remediation is a big challenge of our generation. In this project I am on the one hand interested in the analytical and theoretical means of describing, assessing and working with these large scales. On the other hand, with a background in (computational) chemistry, in the gap that remains between the molecular and macroscopic scale.

Host institute:
C/ Alfonso XII, 62,
Madrid (28014),
Research interests My research interests focus on groundwater and soil characterization and remediation, with the main goal to address and minimize health-related impacts and environmental issues. During my thesis, I characterized and performed geochemical analysis on a contaminant plume derived from a landfill leakage in a small basin in Vitoria, Spain. At AECOM/URS I will be working on contaminated site characterization and Layered Double Hydroxides (LDH) injection to better understand their interaction with chlorinated compounds, their distribution, and mobility in the porous media.

Job opportunities

The Metal-Aid network will train 14 Early Stage Researchers. The research projects are divided into four distinct yet collaborative work packages. To learn more about each ESR project, please see below.


There are no open positions in the network.


Your background can be in a quantitative science or engineering, in physics, chemistry, mineralogy, materials science, geochemistry, hydrogeology, engineering, mathematics or other - it does not matter - but we expect you to be competent with physics, chemistry and mathematics. An interest in materials and their interactions in nature is important.

No experience is required but keen interest and a drive for solving problems is essential as is enthusiasm for working in a team with scientists and engineers from other disciplines and other cultures. Facility with English and another language is required because it will be a broadly international environment and there will be considerable travel for meetings and secondments.

To fulfill the European Commission requirements for this position, the candidate must have, or soon have, a degree that permits him/her to enter a PhD program. This might be a Masters degree, a "diplome", an Honours Bachelor or 4 year Bachelor, or equivalent. The successful candidate must not have a PhD or more than 4 years research experience.

The ITN program was designed by the European Commission for Science (EC) to enhance mobility and training opportunities so one of the requirements is that young researchers be trained in another country than their own. Therefore, the candidate must not have lived for more than 12 months during the past 3 years in the country that will host him/her for the project, i.e. a candidate who has been studying in Germany during the Bachelor can be hosted by a partner in Spain but not in Germany.

All young researchers will be registered for a PhD program. Those employed by the private sector partners will be registered at the university of the closest academic project partner. The training program lasts 3 years. The positions will start in the summer and fall of 2016. In some cases, for a perfect candidate, there is a possibility to hold a position for a few months.

Please see the attached document for details about the Metal-Aid positions and how to apply.  If you apply to several positions in different host countries in the network, please indicate in your cover letter for each institute that you have applied for multiple positions.

Final Metal-Aid meeting and injection experiment: November 2019

Metal-Aid ESRs gathered in Copenhagen, Denmark, in the week from 25 to 29th November, 2019, to assist with a final tank experiment and injection of remediation reagents.  For more information about the week's activities, please click here.

October 2019: Set up of tank for final Metal-Aid meeting and injection experiment

Successful remediation depends not only on the reactivity of the reactant used but also on the distribution of the reactant at the target zone in the subsurface. Within the Metal-Aid project ESR Flavia Digiacomo has already studied the mobility of sulfidized zero valent iron in one dimensional columns. Based on her results we will study mobility in a simple three-dimensional system using a one cubic meter sized container. The aim is to improve our knowledge of injectability and mobility of the particle. At the beginning of October, six of the Metal-Aid ESRs tested the tank setup by conducting tracer tests and analyzing break through curves. Based on these results the final injection setup will be adjusted and a higher amount of sulfidized zero valent iron suspension will be injected at the end of November.

Half-filled tank with tubing connected to sampling ports.

Completely filled tank.

July 22-26, 2019: Mentoring of secondary school student at UCL

In the week of July 22-26, 2019, the highly motivated and inquisitive A Level student E. Tongomo spent her work experience week with ESR Lisa Füllenbach at the Earth Sciences Department of University College London (UCL) to learn about life as a research scientist. During her stay, she first received training to work in a geochemistry laboratory under Lisa's guidance, conducting research on the development of potential materials to remediate heavy metal contaminated wastewaters. In order to evaluate the suitability of a material for such remediation purposes, it is essential to understand its properties and geochemical behaviour before experimentation. Therefore, they mineralogically (morphologically via SEM, and structurally using XRD) and geochemically (chemical composition determined by ICP-OES) characterised the material chosen for this purpose: a natural siderite collected from iron-rich soils in southwest Iceland. In preparation of testing its efficacy for heavy metal adsorption from contaminated waters, they conducted a dissolution experiment to investigate the dissolution behaviour of the microcrystalline soil siderite in acidic aqueous solution (Fig. 1).

After hard but exciting work in the laboratory for geochemistry, they furthermore had the chance to visit the UCL rock crushing laboratory, where PhD colleagues B. Winnard and M. Jefferd demonstrated geophysical experiments on rock samples, conducted to investigate long-term performance of geological storage of radioactive wastes and studying sandstone deformation to better understand fluid flow in rocks. Finally, they enjoyed an excellent guided tour by Dr. O. Regalado Fernandez through the Grant Museum of Zoology learning all about evolution and the history of studying life on earth, finishing off an exciting week of research in the Earth Sciences at UCL, London, U.K.

Each Metal-Aid fellow goes on secondment to one or more secondary host institutes. Updates from the fellows about their experiences while on secondments will be posted here.

ESR Weichao Sun: KU -> NIRAS October-December 2019

ESR Weichao Sun went to Niras for his secondment during the period of October-December 2019. At Niras, Weichao assisted ESR Markus Reischer in the preparation, set-up and initial testing of the tank injection experiment. During this time, he learned about particle injection techniques and monitoring, about hydrogeological concepts and monitoring practices, as well as health and safety regulations and procedures that come with running larger experiments.

Weichao also joined Markus and NIRAS colleagues on a field site investigation in Hagfors, Sweden, where he got trained infield work techniques, including in situ injection of particles, tracing particles using the geoprobe system and data analysis. In this secondment Weichao was exposed to a completely different research field compared to his computational chemistry work, which gave him a completely new perspective of how to apply his work to solve real world problems. At the same time, he got to experience daily routines and procedures in a company setting, which will help him when looking for jobs outside academia.

ESR Lisa Füllenbach: UCL -> NIRAS and KU 19 November – 03 December 2019

At the end of Lisa's second year year, the Metal-Aid ESRs collectively conducted a final, field-scale injection experiment, testing the fate and transport of sulphidised zero valent iron nanoparticles (nZVI) produced by ESR 1 at Copenhagen University (KU) in a tank experiment designed by ESR 12. The design was based on the experimental results from the work on fluorescence dyes as markers for particle oxidation and mobility in anoxic environments by ESR 12 at NIRAS (Copenhagen), and on column experiments focused on the mobility and reactivity of sulphidised nZVI in porous media by ESR 8 (Arcadis) at the Karlsruhe Institute of Technology. During her secondment at NIRAS and KU, Lisa helped prepare, construct and set up the tank experiment. During the experiment, she was responsible for documentation and assisted ESR 12, who led the experiment. As the focus of Lisa's studies lies in testing siderite as a potential material for in situ remediation of contaminated groundwater, however, investigating its efficiency in laboratory experiments, it was of great value to scale up and learn about how to design and conduct a field-scale experiment, to receive training on methods used in field studies and to experience work in a consulting company in general. The injection project further included safety and training on instrumentation, brief data processing and interpretation. Overall, it was a great training experience to work in a highly skilled, motivated and goal-oriented team.

ESR Tobias Linke: UI-> A21 October-November 2019

Tobias spent one month at Amphos21. Together with his fellow ESR Shikhar he worked on a computer model, which combines geochemical reactions and hydraulic flow behaviour to simulate the natural situation in Iceland. This will help to understand the natural observations and the results will be published in a joint article. In addition to working on his own project, Tobias got insight into Shikhar’s work and experienced the daily work in a consulting company.

ESR Fieke Mulders: UCL -> KU October- November 2019

In the Fall of 2019, Fieke spent two months at Copenhagen University on secondment. The aim of her secondment in Copenhagen was to synthesize siderite, an iron-carbonate. Lisa, a fellow ESR, has shown in her work that siderite can effectively be used to remediate soils contaminated with heavy metals, including lead and copper. Additionally, Tobias found that in the soils in Iceland, siderite formed naturally. During Fieke's stay in Copenhagen she wanted to constrain the conditions at which siderite formed and determine how fast siderite grows and how the rate of formation depends on the solution composition.

At Copenhagen University she and other ESRs set-up a glovebox that was filled with 10% CO2 gas and nitrogen. The CO2 gas prevents outgassing of carbonates from the solution and thus crucial when maintaining a constant Fe(II) and carbonate concentration in solution. During Fieke's stay she synthesized several different batches of siderite. She then measured the turbidity of the solution during the formation of siderite, which allowed her to identify different phases of nucleation.

During her time in Copenhagen she worked extensively with Adrian Shiefler (ESR 13), who works at the Capital Region of Denmark. Together they developed a method to measure Fe(II) and Fe(III) concentrations. Development of this method was essential to measure the iron concentrations in Fieke's experiments, but also to constrain the iron distribution in the final injection experiment. Furthermore, Fieke also met several times with Nina Tuxen from the Capital Region of Denmark, both to discuss the details of the injection and to review  progress made during her stay in Copenhagen and her PhD in general.

Aside from the work on siderite formation Fieke also participated in the main injection as well as the trial injection, during which the Metal-Aid group  injected the particles that Marco synthesized in a tank filled with sand.

ESR Marco Mangayayam: KU -> Niras (September 2019)

Marco spent two months for his secondment at Niras A/S. During this period, he assisted Markus Reischer to complete the tank experiment, in particular to documentation of health, safety, and risk factors of the experiment which were performed in Niras facility. Additionally, Marco joined the monitoring and field injection campaign of Niras, which were conducted in Hagfors, Sweden. The field training exposed Marco to the practical on-site injection of reactant materials at field-scale.

ESR Markus Reischer: NI -> KU (01.12.2018 – 31.05.2019)

Markus Reischer focuses in his research on tracing injectants for remediation using a fluorescent sensitive direct-push probe. He spent 6 months at the University of Copenhagen where he investigated how fluorescent molecules can be used to trace sulfidized zero valent iron nanoparticles (sZVI) either by directly grafting the fluorophore directly on the nanoparticle or by using fluorescent sensitive dye sensitive to the nanoparticle. He learned to synthesise various other nanoparticles as model compounds for studying the grafting process and tested in batch studies the potential grafting mechanisms. Absorbance and fluorescence spectroscopy was used for sample analysis. Within this 6 months he went for 2 weeks to the Karlsruhe Institute of Technology where he received training in conducting mobility studies using sand columns. Afterwards he conducted column experiments at KU which helped him to understand the mobility of fluorescent molecules in presence of sZVI.

ESR Marco Mangayayam: KU -> GFZ (May 2017 - July 2019)

During the course of Metal-Aid project, Marco Mangayayam spent a total of 6 weeks of research visits in Helmholtz GFZ, Potsdam. In his first week of secondment (May 2017), he attended a training course in transmission electron microscopy (TEM), which was essential for the upcoming practical and experimental tasks for his project. He utilised this training by performing analytical and high-resolution TEM using a Tecnai G20 in GFZ to understand the morphology of the particles that will be used for in-situ remediation. To ensure the reproducibility of the results, he also performed synthesis experiments in GFZ, typical to his experiments in KU during his last week of research visit (July 2019).

ESR Adrian Schiefler: CRD -> Amphos 21 (4 September to 2 October 2019)

Adrian used his secondment at Amphos21 to learn about the transport models implemented by his fellow ESR Shikhar Nilabh. Adrian was also able to make use of computational resources at Amphos21 to continue work on his X-ray µ-CT data, collected from column experiments at the Spring8 synchrotron facility. The stay enabled fruitful discussion between experimental and theoretical perspectives and finished with a joint presentation in the Amphos21 seminar series. With the gained understanding of existing transport model description, work continues to gain better insights into particle retention in porous media via direct observation using X-ray µ-CT.

ESR Tobias Linke: UI → USAL 07 Feb. – 09 Mar, 2019

Tobias Linke spent one month at the University of Salamanca, Spain. Together with his fellow ESR Karen Dietmann, based at USAL, he analysed solid samples regarding their physical properties, mineralogical composition, shared latest results, and knowledge with fellow researchers of the Metal-Aid project and members of the research group at USAL. These samples were taken during his entire PhD studies at his own field site and from various reference locations throughout Iceland. Carried out analyses, together with elemental chemical analyses, will help Tobias Linke to identify minerals phases and other compounds within the studied samples. Especially, particle size distribution and specific surface area of the characterised solid samples provide important information about potential reactivity and are used to refine geochemical models within the scope of the project Metal-Aid. Results obtained during this secondment, together with previously gathered data of surface and soil water samples, will help to understand the chemical and physical subsurface processes. These mainly include changes due to the exposure to air as well as transportation to the ocean.

ESR Shikhar Nilabh: A21 -> KIT May 6-May 18, 2019

Shikhar Nilabh spent 2 weeks at Karlsruhe Institute of Technology, with the purpose of getting experimental insights to improve his numerical models. During this time, he simulated nano-particle injection in sand column using Flavia´s data and was able to fine tune the results by incorporating relevant ideas and feedback provided by her. Additionally, he learnt about the working principles of the overall column experiment, including the synthesis and injection of nano-particles and their analysis using Inductively Coupled Plasma Mass Spectrometry (ICP-MS)

ESR Adrian Shiefler: CRD -> KU

A secondment at KU for 7 months was carried out during my ESR employment contract to characterize the toxicity of sulfidized nano-Zero-Valent-Iron particles towards bacteria. In a first stage, particle synthesis was adapted from fellow Marco Mangayayam to the needs of study. A method using ATP quantification was developed, to be able to study the impact on mixed anaerobic, dechlorinating cultures. The assay was then used in a screening format to test the impacts of nZVI and differently sulfidized nZVIs on the pure strain Shewanella Oneidensis MR-1, under both aerobic and anaerobic conditions. The assay was compared to classical plate counting and the ATP assay subsequently used to probe for the relevance of hydroxyl radicals under aerobic conditions. Finally, the ATP assay was applied to a commercial bioremediation culture and one, previously derived from the Innovation Garage field site.

ESR Andrew Thomas: KIT -> KU February-May 2019

Andrew Thomas spent three months at Copenhagen University. To explain the results of previous experiments, the particle size and structure of fresh samples of green rust and samples aged for two months were characterized using the XRD and SEM instruments available at KU. In addition, the first draft of a research paper was completed with the help of knowledge shared by scientists at the university.

ESR Markus Reischer: NIRAS -> KIT 03.02.2019 – 16.02.2019

Markus Reischer spent two weeks at the Karlsruhe Institute of Technology to receive training in conducting particle mobility studies by using soil columns. Secondly Flavia Digiacomo showed him how to synthesise sulfidized zero valent iron. With the gained knowledge Markus does his own column studies at Copenhagen University. During the stay Flavia and Markus together visited Thomas Held at Arcadis in Karlsruhe and Thomas introduced Arcadis to them.


ESR Shikhar Nilabh: A21 -> KU (Feb. - March 2019)

Shikhar Nilabh spent one month at University of Copenhagen, with the aim of obtaining kinetic data of sZVI reactivity with chlorinated solvents . He collected groundwater from the field and with the help of Marco Mangayayam, he learnt the procedure for setting up the kinetic experiments and obtaining the contaminant degradation data from GC-MS. During his one month stay, he was able to obtain preliminary results of kinetic rate coefficients for different chlorinated solvents, which will help him in developing a relevant reactive transport model.

ESR Sandra Navaz Rubio: GFZ -> KU and CRD (01/10/18-21/12/18)

To date, my PhD work has shown that GR can efficiently remove Ni and Zn from solution, but little is known about how these metals affect the process of GR formation. To answer this question, I performed titration experiments during my secondment in the University of Copenhagen. The aim was to study whether the pathway of GR formation changes and then, elucidate the mechanism of incorporation of these metals inside the GR structure. Additionally, I have participated, together with ESR7 and ESR13 in a project about the efficiency of GR in removing contamination from the Collstrup injection site, owned by my second secondment host CRD in Copenhagen. During this time, I also learned about field implementation and monitoring at real injection sites. Finally, together with the other ERS’s I will be part of the real injection that will take place in November-December 2019. This will help me learn about and understand how the field data compares with my experimental results.

ESR Jeffrey Paulo Perez: GFZ ->Karlsruhe Institute of Technology (September 2018)

Jeffrey visited Karlsruhe Institute of Technology (KIT) to learn about X-ray absorption spectroscopy (XAS). Together with Andrew Thomas, he collected As and Fe K-edge XAS data on his arsenic-bearing iron (oxyhydr)oxide samples at ANKA-KIT to determine the oxidation state and local bonding environment of both As and Fe. ESR

ESR Karen Dietmann: USAL -> KU  (Feb 9 – March 9, 2018)

Karen Maria Dietmann spent one month at the University of Copenhagen. During her stay she synthesised selected Layered Double Hydroxides under controlled atmosphere and used high resolution techniques to characterise her samples. Knowledge on the retention of chlorinated solvents using Layered Double Hydroxides and Green Rust was shared with fellow researchers of the Metal-Aid project and members of the NanoGeoScience research group.

ESR Flavia Digiacomo: ADE->KU and CRD (21 June- 31 August 2018)

Flavia Digiacomo spent 10 weeks at the University of Copenhagen. During her stay she learned how to synthesize sulphidised Fe reactants (from Marco Mangayayam, ESR 1) and optimized transport column experiments. During the planning phase of the mobility experiments, she worked closely with Shikhar Nilabh (ESR 10). Shikhar shared his knowledge in mathematical modelling with Flavia and gave her useful tips on how to obtain the parameters which are required for mathematical models. In addition, Flavia carried out replicas of reactivity column experiments with green rust reactant and Cr(VI) as contaminant. Furthermore, she had the chance to visit the Innovation Garage at CRD where she joined Adrian Schiefler (ESR 13) for his soil and water sampling.

ESR Shikhar Nilabh: A21 -> KU (Aug 3-Sep 3 2018)

With the purpose of obtaining the column experiment data, Shikhar Nilabh spent three months at the University of Copenhagen where he worked closely with Flavia Digiacomo (ESR 8). Coming from mathematical modeling background, this secondment greatly helped him understand the nuances of the experimental aspect of the project — right from synthesis of the nano-particles to their injection. It took multiple rounds of experiments and discussion to understand the the relevant governing parameters; which was helpful in optimizing the experiments. By the end of his secondment, he obtained the preliminary results of column experiments, which will be required for developing the mathematical models.

ESR Andrew Thomas: KIT->Arcadis (May-June 2018)

Andrew Thomas spent 5 months splitting his time between KIT and the Arcadis office in Karlsruhe. While at Arcadis, he looked at groundwater characterization data from a Cr-contaminated site in Germany and used this data to plan lab experiments and to predict the stability of green rusts at typical Cr-contaminated sites. Also, at the end of the secondment, Andrew visited the Arcadis office in Zürich, Switzerland, presented his experimental results and received feedback from employees working on similar projects. He also toured the office’s lab facilities and advised some employees on their current projects.

ESR Virginia Alonso de Linaje: AECOM-> University of Copenhague/CRD (March-June 2018)

Virginia Alonso de Linaje spent 3 months at the University of Copenhagen. During her stay she characterized modified layered double hydroxides and developed batch experiments to determine their adsorption isotherms for different chlorinated hydrocarbons. In Copenhagen she also visited the Innovation Garage (Capital Region of Denmark). There, she placed some of the most promising synthesized solids in some wells in order to evaluate their stability under natural conditions.

ESR Virginia Alonso de Linaje: AECOM-> University of Salamanca (September-December 2017)

Virginia Alonso de Linaje spent 3 months at the University of Salamanca. During her stay, with the support of ERS Karen Dietmann and Prof. Vicente Rives, she synthesized different modified layered double hydroxides and characterized them with different techniques. She performed batch experiments regarding the stability of the solids under pilot test site groundwater and batch experiments to evaluate the reactivity of the solids with polluted groundwater from the site. Please click here for some photos from her time on secondment.

ESR Andrew Thomas: KIT -> GFZ (July and November 2017)

ESR Jeffrey Paulo Perez: GFZ -> University of Copenhagen (October-February 2018)

Jeffrey Paulo Perez spent 4 months at the University of Copenhagen. During his stay, he performed several experiments to study the formation of green rust from arsenic-bearing ferrihydrite, as well as its transformation to other iron (oxyhydr)oxides such as goethite and magnetite. He also looked at the fate and speciation of the immobilized arsenic throughout these mineral transformation reactions. Jeffrey and Markus Reischer also collected groundwater samples from an arsenic-contaminated site, and set-up batch experiments with Adrian Schiefler to evaluate the stability and reactivity of green rust in these natural environments.

ESR Adrian Schiefler: CRD ->GFZ (September 2017 and February 2019)

Two 1-week visits were undertaken at the GeoForschungsZentrum (GFZ, Potsdam/Germany) for the purpose of training and research. The first visit (4.-7. September, 2017) included training on microbial population analysis via polymerase chain reaction and pyrosequencing (PCR) and synthesis of GR by co-precipitation. The samples were brought from KU and consisted of groundwater communities that were exposed to green rust reactants. Work on the ESR’s samples was supervised by Dr. Stefanie Lutz and included the practical preparation and handling of samples, as well as training on data evaluation using the dedicated bioinformatics software Qiime. The second visit (18-22. February, 2019) included scanning and transmission electron microscopy of bacteria exposed to nano-particles. The work was conducted under supervision of Anja Schreiber, Dr. Richard Wirth, Dr. Sathish Mayanna and Jeffrey P. Perez. The results will contribute to our study on nano-particle toxicity towards bacteria.

ESR Adrian Schiefler: CRD -> Niras

In the first half of 2017, regular meetings were held at the consultancy Niras with the project teams of Niras, Capital Region and also Copenhagen University. The purpose was to discuss the possibilities and necessary conceptualization of a field injection with the test site “Innovation Garage” in mind. The visits also served the purpose of understanding the consultancies workflow, internal capacities (direct push injection via the Geoprobe system) and outsourced work packages (e.g. parts of groundwater analysis). In anticipation of an injection, several field campaigns were conducted at the Innovation garage under supervision of Niras. The purpose was to receive training on field sampling and groundwater analysis, as well as a thorough mapping and understanding of the site in terms of contamination, hydrogeology and natural attenuation processes taking place. The campaigns covered a period of 14 days and took place from November 14th to 17th in 2016 and February 20th to 23rd, April 19th to 21st and June 6th to 8th 2017. As a result of these campaigns we published our findings in the Elsevier Journal Energy Procedia [1].

During the event, ESRs gave oral presentations on their research to date.  An agenda for the event is available here.  This network event was also used for the annual self evaluation with discussions in work packages about progress and challenges to date.

Fifth Metal-Aid network event: Reykjavik, Iceland: Large scale outreach event

The fifth Metal-Aid network event took place in association with the International Carbon Conference in Iceland in September 2018.  The International Carbon Conference (ICC-2018) is an outreach conference reuniting five different networks. Two days before the conference, individual networks ran their own management meetings. Parallel with that, Metal-Aid ran a summer school for early stage researchers at the Hellisheidi site on September 11th, where they got hands-on training in sampling geothermal gases, ground- and geothermal- water, and two-phase-flow geothermal wells. Following the outreach meeting on September 12th the Metal-Aid members took part in a field trip to the Eyjafjallajökull, and Eldfell volcanoes to study the environmental impact of the 2010 Eyjafjalljökull eruption and the Eldfell 1973 eruption within the town of Vestmanneyjar South Iceland. The early stage researchers presented posters at the poster-session that was part of the ICC-2018 conference and three of the Metal-Aid PI’s (Eric Oelkers, Susan Stipp and Sigurdur Gislason) chaired 3 of 4 of the oral sessions. Metal-Aid coordinator Dominique Tobler gave an invited talk on the Metal-Aid network in the first session of the ICC-18. Metal-Aid members chaired the Scientific, Organisation and the Editorial Committees. Selected papers presented at the ICC-18 conference were published in Energy Procedia before the meeting‐procedia/vol/146.
