A leakage of CO2 from a geological storage site into an aquifer exploited for human use could raise concerns about potential changes groundwater quality. We the reactive transport code TOUGH2-ECO2N/TOUGHREACT in order to apprehend possible geochemical mechanisms that affect freshwater aquifer. Our model is based on mineralogical and features existing glauconitic-sandstone aquifer, which trace elements bearing minerals are added average proportions found similar mineralogies. The computes...
Artificial recharge (AR) is gaining importance as a management tool in water stressed regions. The need to prove recovery performance requires new monitoring tools for AR systems. A novel combination of environmental isotope tracers (B, Li, O, H stable isotopes) was tested the tertiary treated, desalinated domestic wastewater into coastal dune aquifer Flanders, Belgium. No significant fractionation observed treatment process, which includes low pH RO desalination. wastewater, after...
Contamination of fresh groundwater is one the environmental issues Carbon Capture and Storage. We simulate with reactive transport code TOUGHREACT intrusion CO2+ impurities from oxycombustion capture in a freshwater aquifer model based on glauconitic sandstone aquifer. choose an unfavorable scenario where contaminant gas presents maximal contents SOx, NOx O2. Water quality changes after 10 years are exposed. French standards pH, Fe, Mn sulphates concentrations for drinking water reminded...
Soil Aquifer Treatment (SAT) can provide supplementary treatment of trace organic compounds (TrOCs) such as pharmaceutical and industrial present in Secondary Treated Wastewater (STWW). Concern on presence unregulated TrOCs natural systems has raised recently well the interest SAT for remediation. The study quantifies, at field scale over35 m lateral groundwater flow, effectiveness Agon-Coutainville system (Manche, Normandy, France) removal by sorption biodegradation through monitoring seven...
The demand for energy and chemicals is constantly growing, leading to an increase of the amounts contaminants discharged environment. Among these, pharmaceutical molecules are frequently found in treated wastewater that into superficial waters. Indeed, treatment plants (WWTPs) designed remove organic pollution from urban effluents but not specific, especially toward emerging concern (CECs), which finally reach natural In this context, it important study fate micropollutants, a soil aquifer...
For carbon dioxide capture and storage to make an effective contribution in reducing greenhouse gas emissions, a large number of sites will be required. Safety have demonstrated for each these sites. We present this paper simple flexible framework assess safety CO2 site time-efficient manner. It includes the identification by expert panel relevant risk scenarios. Their evaluation privileges analytical or semi-analytical modelling with conservative assumptions. Uncertainty is managed order...
The main objective of this study is the establishment innovative purification systems through conceptualisation reactive barriers in soil for artificial recharge groundwater with treated wastewater. Numerical integration hydrodynamics and biogeochemical processes controlling effectiveness engineering system applied to design column experiments. This leads elaboration a combined aerobic/anaerobic environment ensure successive nitrification rich ammonium wastewater denitrification mechanisms...
We present a panel of numerical modeling studies aimed to improve groundwater management resources for different contexts in the Northern part France (the 'Hauts-de-France' Region). The objective is demonstrate capacities and limitations tools reproducing observed data providing predictions on evolution under increasing anthropic pressures climate change. Numerical models are developed 3D at regional scale evaluate various scenarios management, considering several types or natural...
The combination of managed aquifer recharge (MAR) with soil-aquifer treatment (SAT) has clear advantages for the future sustainable quality and quantity management groundwater, especially when using treated wastewater. We built a Marthe flow transport model an MAR–SAT system located in near-shore sand aquifer, quantifying influence environmental factors (climate, tides, operational conditions) on coastal hydrosystem regard to fate trace organic compounds (TrOCs). simulations show impact...
Le travail abordé ici s'inscrit dans une étude globale de mise au point d'outils caractérisation et modélisation flux polluant transporté par l'eau (approche quantitative) transitant la zone non saturée d'un sol.Le présente, un premier temps, démarche d'étude suivie pour caractériser modéliser les écoulements pollués sol saturé provenant sites pollués.Puis deuxième réalisation d'une des étapes : validation l'outil choisi, travaillant éléments finis, sur expérience d'infiltration référence.
