Introduction
Both expert in diffuse pollutions and compounds of emerging concern in groundwater, and in statistical data analysis of groundwater quality. Leading and active participation to European working groups that link EU governments, other EU bodies, international organisations, medical professionals, academics, researchers, NGOs and the business community. Strong interests and focuses on skill and knowledge transfer from research domain to water management, regulations and European policies.

Article
Full-text available
In Europe, emerging organic compounds (EOCs) in groundwater is a growing research area. Prioritisation for monitoring EOCs in Europe was formalised in 2019 through the development of the first voluntary groundwater watch list (GWWL). Despite this, groundwater occurrence data in the peer reviewed literature for Europe has not been reviewed to date....

The Partnership for Chemicals Risk Assessment (PARC) is currently under development as a joint research and innovation programme to strengthen the scientific basis for chemical risk assessment in the EU. The plan is to bring chemical risk assessors and managers together with scientists to accelerate method development and the production of necessar...

Sustainable groundwater management relies on data to establish resource conditions and measure the effects of management intervention. As groundwater management grows in size and complexity so does the data needed to inform it, and the systems needed to manage this data. This chapter presents a discussion of groundwater information systems, their h...
Article
Full-text available
There is growing concern globally about the occurrence of anthropogenic organic contaminants in the environment, including pharmaceuticals and personal care products. This concern extends to groundwater, which is a critical water resource in Europe, and its protection is a priority to the European Commission, the European Union (EU) Member States a...
Article
Full-text available
La surveillance des eaux souterraines est composée d'analyses " photographique " et " intermédiaire " larges, sur un nombre important de substances dont celles d'intérêt émergent, et ce afin de vérifier qu'il n'y a pas de quantification inattendue et de cibler des surveillances complémentaires à mettre en place. Ces " screening " sont complétés par...
Conference Paper
Full-text available
Groundwater can represent a boundary condition for the dynamics of water into the critical zone. Groundwater level fluctuations influence several hydrodynamic and geochemical processes in the non-saturated zone such as, droughts and floods, rock-water interactions, surface water and soils quality, climate variability and change impacts… Several dif...
Article
The occurrence and spatial distribution of 22 selected perfluoroalkyl and polyfluoroalkyl substances (PFASs) in surface water (n=75), groundwater (n=80) and surficial sediment (n=15) were investigated for the first time in the tropical areas constituted by the French Overseas Territories (French Guiana, Guadeloupe, Martinique, Mayotte and Reunion)....
Conference Paper
Full-text available
In 2012, perchlorate ions were found in a multi-layers sedimentary aquifer, located in the center of France in agricultural land use, partly exploited for irrigation and to supply major cities in fresh water. The concentrations measured in several agricultural and water supply catchments exceed the 4 and 15 µg/L values defined by the WHO (World Hea...
Conference Paper
This study follows the recent findings of perchlorate ions in several French aquifers, and particularly in the South-West and in the North of France. The concentration measured in groundwater can exceed the 4 and 15 µg/L values defined by the WHO (World Health Organization) as toxicity thresholds for infants (and pregnant women) and adults, respect...
Article

Nationwide screening of 411 emerging contaminants and other regulated compounds, including parent molecules and transformation products (TPs) having various uses and origins, was done at 494 groundwater sites throughout France during two sampling campaigns in the Spring and the Fall of 2011. One hundred and eighty substances (44% of the targeted co...

L'étude prospective réalisée en 2012 s'intègre dans les travaux du plan d'action national pour lutter contre la pollution des milieux aquatiques qui prévoit, dans son action 16, la mise à jour des listes de substances qui doivent faire l'objet d'une surveillance. Cette étude " R&D " a été conduite en métropole et dans les 5 DOM (Martinique, Guadelo...
Conference Paper

In 2011, the French Ministry of Ecology and the Water and Aquatic Environment National Office have implemented a national screening campaign in groundwater focused on occurrence of "emerging" organic contaminants with various potential uses and origins. Among the 411 Organic compounds (OC) targeted, 131 pharmaceutical products, 13 life style produc...

In 2011, the French Ministry of Ecology and the Water and Aquatic Environment National Office have implemented a national reconnaissance effort targeting "emerging" organic contaminants with various potential uses and origins. This study presents this national screening and fully discusses the occurrence of selected organic compounds (OCs) in groun...

La modélisation globale des concentrations en nitrate peut être utilisée avec succès pour simuler les tendances observées et les extrapoler dans le futur. Elle est réalisée au BRGM à l’aide du modèle BICHE, basé sur la simulation globale des écoulements à l’échelle du bassin versant selon un modèle à réservoir, et sur le transport de nitrates que c...
Article
Le modèle BICHE (Bilan CHimique des Eaux), développé au BRGM, est un exemple de modèle global permettant de simuler les flux d'eau et de nitrates d'une nappe à l'échelle du bassin versant à partir de chroniques de pluie, d'ETP, de données agronomiques et de chroniques de calage (concentrations et débits ou niveaux de nappe). Une étude menée sur le...

À l’heure où les autorités s’interrogent sur l’efficacité des mesures agro-environnementales et mettent en place un renforcement de la politique de protection de la ressource en eau face aux pollutions diffuses (Grenelle de l’environnement), les outils manquent pour prédire le réel impact de ces mesures et l’évolution de la qualité de l’eau dans le...
Article
The European Union (EU) has adopted directives requiring that Member States take measures to reach a "good" chemical status of water resources by the year 2015 (Water Framework Directive: WFD). Alongside, the Nitrates Directives (91/676/EEC) aims at controlling nitrogen pollution and requires Member States to identify groundwaters that contain more...

Project
Industry plays an important role in supporting the circular economy. To help Europe reach its ambitious Green Deal objectives, the EU-funded PROMISCES (Preventing Recalcitrant Organic Mobile Industrial chemicalS for Circular Economy in the Soil-sediment-water system) project will identify how industrial pollution prevents the development of a circular economy in the EU and detect strategies to overcome the principal bottlenecks that impede reaching the targets of the European Green Deal and Circular Economy Action Plan. The project will develop new analytical methods and toxicological tools to deliver data on persistent, mobile (PM) substances in complex environmental matrices and investigate sources of PM substances released from soil, sediments, landfills and wastewater treatment plants and via urban runoff into relevant natural systems. PROMISCES will assess fate and transport processes and improve the assessment and management of human health risks.
