Water is essential for the human body to function properly which is why so much importance is given to water supply and water quality. Surface waters and groundwater are the main sources used to provide tap water, or municipal water, to the public. Tap water is treated to ensure compliance with about 60 microbiological, physico-chemical, radiological and organoleptic parameters described in European regulations which are transposed into national law. The extent of water treatment depends on the quality of the resource with the aim of eliminating pathogenic microorganisms such as bacteria, viruses, and parasites, chemical contaminants including for example pesticides and nitrates, and excess mineral salts like fluoride and sodium, among others. See ANSES’s work on this topic.
Pesticides in tap water: regional variations do not alter the findings of the national risk assessments
Like other foods, tap water is susceptible to contamination by pesticides. ANSES conducted a dedicated study to assess water’s share in overall dietary exposure to pesticides and the consequences of geographic variability in contamination in terms of risk.This study,conducted in the context of the missions of the French Observatory for Pesticide Residues (ORP), was funded by the French National Agency for Water and Aquatic Environments (ONEMA) as part ...

Water intended for human consumption comes from ground and surface water which is treated to make it drinkable. Depending on the natural environment from which this water comes, it may contain various natural or man-made chemicals chemicals. Upon a request by the Ministry of Health, ANSES evaluates health risks related to the presence of regulated or unregulated chemicals in water intended for human consumption. A description of this work is given below.
For users to have good quality tap water, it is necessary to have good quality water resources. The quality of water resources must therefore be maintained by protecting them. For this purpose, protected areas are defined around catchment sites, and these are called catchment protection zones. ANSES is responsible for assessing the risks associated with various practices that may affect the quality of resources, such as the underground storage of gas or the installation of systems for recovering renewable energy in catchment protection zones.
