Research topic
Dynamics of SOM transformation to improve soil function and productivity by addition of reusable waste materials
Work package
Restoring marginal land for agriculture using low cost amendments and bioremediation
Current research
Low-technology agricultural management practices have been identified as a key to sustainable agriculture through the use of recyclable waste. Soil organic matter (SOM) is beneficial for improving soil function and fertility, and its content is increased through the application of organic matter. The heterogeneous nature of soils coupled with limited understanding of SOM transformation dynamics hinder reliable modelling to predict the performance of diverse amendments in different soils.
The project aims to develop an amendment programme for marginal and contaminated lands utilizing biochar and brown coal from agro-industrial waste products. The efficiency of these amendments will be tested through analysing data from existing long-term field experiments supported (when necessary) by laboratory studies and field trials. Laboratory analyses will be limited to the determination of carbon and nitrogen contents in soil, extraction of humic acids and their qualitative analysis (NMR, EPR, etc.). A field-scale plot will further test the efficiency of studied SOM sources. An expected research output is a generic (semi-quantitative) model developed based on the parameters derived from on-going laboratory and long-term field data from the Experimental Station in Skierniewice, Poland, and other station(s) defined during the realization of the project. It is also expected that the research will be the basis for a PhD thesis and contribute to the advancement of current scientific knowledge in this area. The research will be conducted in cooperation with the INSPIRATION partners: University of 91探花, UK, Wageningen University, Netherlands and TEAGASC, Ireland.

Research interest
The main focus of the project is to develop and test stable isotope based techniques for the identification and quantification of prevailing phosphorous/nitrogen transformation pathways in surface and subsurface catchments that are impacted by intense agricultural land use.
Profile
I am a graduate student in Environmental Sciences with a great interest in water protection. During my Master鈥檚 thesis I studied the Iseo Lake (Lombardy). From the 1970s the lake has undergone a dramatic deterioration in water quality due to ANTHROPOGENIC and climate change impacts. The main issue in this lake is the excessive load of nutrients (nitrogen and phosphorus), largely affected by anthropogenic activities. During my master I also joined some field work activities as a research assistant to study the impact of cryosphere degradation on high altitude alpine ecosystems. After my graduation I spent almost six months in Troms酶, Norway, studying the impact of climate change on benthic communities in two fjords in Svalbard.

Research topic
Quantifying the phosphorus flux leaching from field to groundwater and surface water using innovative techniques
Work package
Development of innovative methodologies for measuring fluxes of agricultural chemicals in the subsurface
Current research
Phosphorus (P), a limiting nutrient in the water bodies, often exceeds its (ecological) threshold limits in many European freshwater lakes, reservoirs and small streams thereby resulting in algal blooms causing eutrophication. P losses through agriculture is believed to be the major cause of eutrophication. There is substantial research since the 1980s to improve the understanding of the origin and provenance of P loads in surface water and its transport from agricultural land to surface water. Without exception, almost all the studies classified P loads in surface waters coming either from (1) industrial point sources, (2) agricultural diffuse sources, or (3) agricultural surface runoff and drain flow. Based on these studies, policies were implemented to reduce the P fertilizer inputs in agricultural soil, but the surface water quality on a larger scale still remains to be moderate. Hence it is unclear if the primary action plan from EU鈥檚 policies to tackle eutrophication by reducing P fertilization by lowering the fertilizer application standards is really an effective tool or not.
It is still a common paradigm among practitioners to think of P as immobile in groundwater due to adsorption and chemical bonding with other existing minerals to form complex metal compounds. But this notion is incorrect in regions which are characterised by the presence of sandy soils and have huge historical P accumulation over decades. In such conditions, leaching might be the main contributor to P loading on ground and in surface water. Although there is a vast literature behind P mobility in soil and surface water, surprisingly, there is very limited quantitative understanding of P transport fluxes in the groundwater. The scarcity of data on P-fluxes in groundwater certainly limits considerations in the aspect of solving the eutrophication problem. This proves the urgency in developing an alternative methodology to accurately measure P leaching losses which will effectively estimate the P loads to ground and surface waters. To do this, good understanding and accurate quantification of P-fluxes in the groundwater would be the key requirements.
Till now, groundwater pollution has been mostly measured in terms of solute concentration, but mass flux and mass discharge calculations are essential to completely understand and estimate the groundwater contamination hence helping in quantifying and monitoring the excess nutrients. This research will focus on the execution and interpretation of flux measurements to estimate P losses from soil leaching in groundwater. Hereby, different conventional and innovative measurement techniques like the 鈥渋FLUX sampler鈥 developed in collaboration between VITO and University of Antwerp will be applied and compared. Ultimately, this doctoral study aims at bridging the existing knowledge gap with respect to P transport from agricultural soils through leaching by providing complete understanding and correct quantification of P fluxes in groundwater.

The aim of the research is to quantify C and N transport between compartments and scales in agricultural catchments, considering relevant hydrological and biochemical processes, using hydrogeochemical and stable isotope techniques. The research will use laboratory, field and modelling studies to quantify biogeochemical processes and recognize hot spots, hot moments and functional zones controlling nutrient fate at catchment scale.

Research topic
Development of adequate sensors for monitoring nitrate (or other agrichemicals of interest) in groundwater.Work package
Development of innovative methodologies for measuring fluxes of agricultural chemicals in the subsurface.
Current research
The main focus of this research project is the development and application of a monitoring device that will detect and monitor continuously agricultural contaminants (nitrate and/or other agrichemicals) in the groundwater. The existing methodologies and tools for monitoring the contaminant fluxes in the subsurface and groundwater allow either 鈥渟nap鈥恠hot鈥 retrieval or cumulative (passive) sampling of the contaminants. The monitoring device to be developed will enable to recover a time series of groundwater and contaminant fluxes in order to better evaluate their variability with time. This is particularly important in the agricultural context where time variations in recharge processes and piezometry often strongly influence the mass fluxes of agrichemicals to and in the groundwater.
The main steps of the research are: (1) Selection of the appropriate technique for the monitoring of the agricultural pollutants of interest and development of the sensor in the laboratory. The sensor will be initially tested at laboratory scale with synthetic and/or groundwater water samples. (2) Development of the monitoring unit to be deployed in the field. In this step, feedback from the previous step will be used and instructions will be given to Citius Engineering Team who will participate in the assembling and development of the unique device. (3) Implementation of multiple field tests with the monitoring device in order to better understand the dynamics of pollutant fluxes in the groundwater. This step will also enable the estimation of contaminant travel times from several locations in the agriculturally impacted catchment under investigation.

Mitigation of soil and groundwater impacts from agriculture using mixed waste media
Current research
At present on intensive agricultural sites across the EU, nutrients are being lost to the environment at distinct delivery points. Recent research has identified engineered structures filled with reactive media can control such losses but pollution swapping can be an issue.
My PhD project will employ a combination of laboratory and field scale experiments for the development of a novel bioreactor technology to control excess nutrients at distinct delivery points e.g. from artificial drainage systems. Initially, a selection of locally sourced biodegradable waste materials across a spectrum of adsorption capacities will be tested at batch scale followed by a controlled laboratory column study utilizing different operational conditions. Such studies will identify the most efficient media for mitigation of mixed contaminants, whilst minimising pollution swapping. After this phase the best performing media will be tested at field scale. In parallel, a model will be developed that aids the design and sizing of field bioreactors but also incorporating pollution swapping concepts.
The main research activities and all related laboratory and preliminary filed-scale tests will be carried out at the Johnstown Castle Research Centre in Wexford, Ireland. I am registered as a PhD student in NUI-Galway. My ESR11 is linked with ESR12 (TLB), and ESR13 (UFZ). This ESR is also supported by USFD, WUT and EAWAG.

Work package
Predicting catchment-scale nutrient and contaminant fluxes between environmental compartments
Current research
In the face of global climate change the problem of inland waters鈥 contribution to GHGs emission becomes increasingly important, especially in the quantitative aspect. Recent studies suggested that the groundwater system might be a significant source of the GHGs emission occurring on the surface water-atmosphere interface. However, currently the transfer processes of CO2, CH4 and N2O in the subsurface are poorly understood due to the limitations of methodologies for quantifying fluxes and insufficient insight into the kinetics and controls of processes regulating their production, transport and consumption. That is why this project focuses on the study of the groundwater contribution to GHGs emissions from inland waters, with the particular attention to groundwater systems located in agricultural areas that are often considered as a 鈥渉otspots鈥 of GHGs evasion.
It is expected that spatially distributed regular sampling of groundwater across the areas of interest at different depths along the vertical profile (i.e. unsaturated and saturated zones) and along the groundwater flow path (including the groundwater-surface water interface) will be conducted in the framework of this research.
Furthermore, stable isotope techniques will be applied in order to analyze the dynamics of greenhouse gases production and consumption. Groundwater modelling techniques will be used in order to estimate temporal variations of groundwater GHGs fluxes. As a result, this project could help to develop methodologies for the quantification greenhouse gases budgets and obtain valuable information regarding the dynamics of GHGs transfer in the groundwater systems and its controls.

Developing a framework to establish cost-effective measures to reduce pesticide impacts on a catchment-scaleWork package
Sustainability of agricultural management strategies at the catchment-scale
Current research
Under the Water Framework Directive, EU Member States should organise cost-effective measures to ensure sufficient quantity of good-quality water available for people鈥檚 needs and the environment. Pollution from agricultural activities is diffused in the environment often without treatment or targeted mitigation. Mitigation measures, like vegetated buffer strips, constructed wetland, riparian buffer strips, can minimise the risk of off-site water pollution caused by spray drift, drain flow and runoff. The effectiveness of measures was tested mostly at field level. There is need to scale up knowledge from farm level to catchment level and contribute to a better management of natural resources.
This research will evaluate the effect of different measures in multiple locations in a catchment setting. How to target actions and to identify priority areas will be analyzed through the development of a GIS-based methodology providing valuable information prior to the setup of a program. The effectiveness of several mitigation measures implemented in a catchment will be assessed from long-term monitoring datasets from a study site in Belgium.
The overall main goal of this study is to build a decision-support framework coupling an environmental model with an economic model to select the most cost-effective measures to reach a certain pesticide reduction goal at the outlet of a catchment. This tool will be used to compare and spatially optimise scenarios balancing environmental and agro-economic impacts at the catchment scale.

Predicting catchment-scale nutrient and contaminant fluxes between environmental compartments
Current research
Within this project I will create a numerical groundwater flow and transport model for a catchment in Switzerland. This model will tie into the work done by Robin Weatherl (ESR 4) in a joint effort to create an adaptive site monitoring scheme for urban and agricultural contaminants, creating the basis for better sensor placement and the identification of potential contamination source zones. At later stages, the nitrogen flux dynamics identified by Izabela Bujak (ESR 3) might be included into the reactive transport section of the model. During this project I intend to create a finite element model of the catchment using Feflow, which will later be replaced by (and serve as a benchmark for) an analytic element model. The final model should be capable of reverse reactive transport and particle tracking without a-priori knowledge of zones of special interest. My current work focuses on the delineation of reasonable Neumann boundary conditions for the study catchment. In the near future I plan to explore the potential of microbial fuel cells as biosensors under field conditions.

Developing Biosensors as smart monitoring tools to assess the restoration performance of biochar amended soilWork package
Restoring marginal land for agriculture using low cost amendments and bioremediation
Current research
Biosensor is an emerging field in sensing technology which is very useful to measure the bioavailability of pollutants compared to conventional methods. It also offers rapid, simple, flexible, and sensitive analysis of pollutant. Biochar is porous carbon material produced from biomass pyrolysis resulting in large surface area and high porosity to retain organic or inorganic pollutants. It is very potential to be applied as simple and low cost remediation technology to restore the contaminated soil.
The objective of this research is to develop biosensor-based methodology to measure the bioavailability of heavy metals (HMs) and Polycyclic aromatic hydrocarbons (PAHs) in contaminated soil treated by biochar. This research will be conducted at lab and field scale. The lab experiment will involve molecular biology approach (e.g DNA extraction, amplification and cloning) to develop the whole cell-based biosensor using strains of microorganisms exposed to HMs and PAHs noting their metabolic responses. The genes which regulate these responses in the identified microorganisms will be characterised and fused with selected luminescence genes to create the biosensor. Another approach by using Fluorescent Resonance Energy Transfer (FRET) sensor also will be conducted. Then the developed biosensor will be tested in field trials to measure its robustness and sensitivity level. The field trial will use plant growth in contaminated soils treated with different biochar types. Sampling and monitoring of bioavailable pollutants by the biosensor, the associated microbial activity, and plant growth will be undertaken during the treatment progress to validate the methodology. This biosensor methodology can then be used to assess the restoration performance of biochar applications in contaminated soil remediation.

Research interest
Current population growth, as well as the industrialisation is causing more pressure over agricultural land production. The intensification of agriculture is needed, however it is impossible to deny the negative effects it may cause: changes in soil structure and chemistry as well as a major shift in biological activity.
Profile
My concern about the deterioration of the environment and the need to find solutions motivated me to study Biotechnology Engineering at the University of the Army Forces (ESPE) in my home country, Ecuador. My Bachelor thesis focused on bioremediation of crude oil polluted soils from the Ecuadorian amazon using wild bacterial strains. After graduation, I worked for 2 years in private companies as a consultant for biological waste water treatment as well as bioremediation processes. In 2012, I got a scholarship offered by SENESCYT (Ecuador) to study a Masters degree in Environmental Sanitation at the University of Ghent in Belgium, where I specialised towards water technologies. My Masters thesis explored carbon stock estimation in aboveground biomass of reforested areas in Ecuador. After finishing my Masters degree on 2014, I went back to Ecuador, where I worked as lecturer at Universidad Tecnica del Norte, until becoming an early stage researcher in the Inspiration network.

Restoring marginal land for agriculture using low cost amendments and bioremediation
Current research
Current population growth, as well as the industrialisation is causing more pressure over agricultural land production. The intensification of agriculture is needed, however it is impossible to deny the negative effects it may cause: changes in soil structure and chemistry as well as a major shift in biological activity. It is necessary to identify low cost solutions that can improve soil productivity and bio-restore contaminated land. Under the framework of work package 3, this project aims to assess the effect of biochar as soil amendment, as well as a to evaluate the potential for it to be used in remediation of heavy metal polluted soils. The project has 4 stages, 1) literature analysis, 2) sorption experiments to determine sorption capacities and kinetics with different heavy metals and desorption patterns, 3) laboratory incubations to determine the effectiveness of biochar to improve soil quality under lab conditions. In this stage, the biosensor developed by ESR 9 will be used as well as SOM amended soil samples provided by ESR 10 from the University of Warsaw in Poland; 4) field trials will be developed for 4 months to evaluate the success of biochar under environmental conditions (collaboration of ESR 9 is expected).
The expected outcomes of this project are:
- To develop a performance criterion for the selection and use of biochars considering effects on soil biota, bioavailabilty of contaminants and end point/objectives
- Field scale verifications, settings and soil conditions
- Methodology to improve productivity of contaminated, SOM-poor marginal soil using biochar.

Research interest
My research focuses on groundwater contamination and transport within a catchment in Switzerland. This area is dominated by urban activity, industrial activity, and vast agricultural fields (crops, orchards, and pastures).
Profile
I grew up in Houston, Texas and hold a Bachelor degree in Physics from the University of Texas at Austin. After several internships with Total in Pau, France, I enrolled at the University of Li猫ge in Belgium and obtained a Master in Geological Engineering in 2016. During my studies in Li猫ge I focused on projects in Hydrogeology and took the time to learn about commonly used field measurement and monitoring techniques. My master thesis focused on groundwater salinization and SW-GW interactions in the Senegal River delta.
I joined Eawag in D眉bendorf, Switzerland as an Early-Stage Researcher in December 2016. I am jointly enrolled as a PhD student at the University of Neuch芒tel, although all of my research will be carried out in D眉bendorf. I am looking forward to the research project with Eawag, which focuses on groundwater flow and contamination issues.

Predicting catchment-scale nutrient and contaminant fluxes between environmental compartments
Current research
My research focuses on groundwater contamination and transport within a catchment in Switzerland. This area is dominated by urban activity, industrial activity, and vast agricultural fields (crops, orchards, and pastures). A significant portion of the municipal water supply is extracted directly from the aquifer below the city, with multiple extraction wells located in the city limits.
My objective is to characterise the study area by collecting data using various hydrogeological field techniques. A number of new piezometers must be installed for measurement points. One of the most important aspects of this work will be to design and implement an adaptive sensor network that will have the capability to collect temporally pseudo-continual parameters of interest and include an automatic sampler. This will ideally be a wireless network that can communicate between nodes and transmit data automatically to a given server. This sensor network will have the potential to collect data on hydrodynamics, hydrochemistry, geophysics, and microbial activity, among other parameters. Traditional field methods (slug tests, hydrogeophysics, sampling campaigns, core analysis, etc.) and lab measurements (ionic analyses) will supplement this sensor network. The field aspect of this project will be carried out in partnership with a numerical modelling aspect led by Maximilian Ramgraber.
The expectation is that this aquifer will be properly characterised with flow paths, sources of various contamination, and subsequent behaviour of contaminants. This information can then be used in a move towards more sustainable urban development and agricultural practices.

Sustainability of agricultural management strategies at the catchment-scale
Current research
Many issues emphasise the need for integrated management strategies to allow agriculture to intensify sustainably. These include, among others, a growing population, increasing fertiliser use, and environmental degradation. The objective of this project is to develop a spatially-explicit decision making framework, integrating technical options and actors at relevant scales for the selection of management approaches that minimise agricultural impacts on soil and groundwater. As part of WP5, collaboration will take place with ESR15 and VITO.
The first objective is to derive sustainability indicators and critical values from literature with the purpose of evaluating management strategies in terms of organic matter, nutrients, and metals, based on local agro-ecosystem properties and as a function of time. Sustainability indicators will address environmental quality, with a focus is on carbon, phosphorus, and nitrogen cycles, as well as compaction. To quantify impacts, a meta-analysis or model approach will be used to develop simple algorithms coupling management strategies (fertilisation, crop rotation, and leaching or runoff) to impacts (soil carbon, phosphate, nitrogen, and compaction). The second objective is a flexible model framework integrating the indicators using multi-criteria analysis to evaluate soil and nutrient management, with the goal of maximising agricultural intensification (fertiliser use efficiency, crop yields, land use) and minimising negative environmental externalities. The final task is the creation of a user-adaptable optimisation technique spanning spatial and temporal scales to select management options. It will be tested in a specific spatial context, for the end result of a dynamic on-line decision support system for stakeholders and policymakers.

Mitigation of soil and groundwater impacts from agriculture using mixed waste media
Current research
Low-cost and low-technology solutions are needed for a sustainable intensification of agriculture. In Europe, the intensive use of agricultural fertilisers has been one of the main causes of water bodies鈥 pollution and eutrophication, leading to a significant degradation of water quality. While an external output of nutrients is required to increase crop production, in wastewater treatment facilities nutrients have to be removed. Therefore, significant savings could be achieved if novel waste materials are studied and used for nutrient recycling from wastewater streams to agricultural soils. To be sustainable, these waste materials have to increase plant nitrogen (N) and phosphorus (P) uptake while minimizing nutrient loss to water and greenhouse gas (GHG) emissions.
The aim of ESR12, with support from NUI Galway and Teagasc, is to search for and test different alternatives of locally sourced materials that can recover nutrients from waste (in collaboration with ESR11) and can be safely applied back to land avoiding groundwater, surface water contamination and GHG emissions. To achieve these objectives, different media will be saturated with N and P from waste streams and then laboratory incubation studies and pot tests will be performed to evaluate the plant availability of nutrients, contamination risk and gaseous emissions.
Some of the expected outputs are a dataset of maximum adsorption capacity and fertiliser replacement equivalence of the waste materials, a report about their effect on runoff, leaching and GHG emissions, and a spreadsheet design tool and guidelines for the use of recycled nutrient waste material amendments on different soil types.
