Une mission inter-inspections r\u00e9unissant l\u2019Inspection g\u00e9n\u00e9rale de l\u2019environnement et du d\u00e9veloppement durable (IGEDD), l\u2019Inspection g\u00e9n\u00e9rale des affaires sociales (IGAS) et le Conseil g\u00e9n\u00e9ral de l\u2019alimentation, de l\u2019agriculture et des espaces ruraux (CGAAER) a analys\u00e9 l\u2019ampleur de la pollution de l\u2019eau destin\u00e9e \u00e0 la consommation humaine par les pesticides et les compos\u00e9s per- et poly-fluoroalkyl\u00e9s (PFAS) en France, ainsi que les co\u00fbts potentiels associ\u00e9s. Elle propose une strat\u00e9gie d\u2019actions gradu\u00e9e et territorialis\u00e9e, combinant mesures pr\u00e9ventives et curatives, pour prot\u00e9ger les populations et limiter la hausse du prix de l\u2019eau, en mobilisant davantage les principaux \u00e9metteurs dans le financement de la d\u00e9pollution.<\/p>\n
En 2024, un peu plus de 29 % de la population fran\u00e7aise a \u00e9t\u00e9 expos\u00e9e, via l\u2019eau de consommation, \u00e0 des niveaux de pesticides ou de PFAS d\u00e9passant les limites de qualit\u00e9 fix\u00e9es au niveau europ\u00e9en. Les restrictions de consommation de l\u2019eau du robinet pour raisons sanitaires demeurent rares, mais plusieurs facteurs laissent anticiper une augmentation des non-conformit\u00e9s dans les ann\u00e9es \u00e0 venir : difficult\u00e9 de mesurer l\u2019ensemble des pollutions, caract\u00e8re persistant et usage continu de certaines mol\u00e9cules, \u00e9largissement du champ des substances d\u00e9tect\u00e9es ou r\u00e9glement\u00e9es.<\/p>\n
La mission souligne le caract\u00e8re pr\u00e9occupant de cette situation pour la sant\u00e9 publique, en raison d\u2019expositions chroniques et d\u2019effets combin\u00e9s de multiples substances. Les pollutions fragilisent l\u2019acc\u00e8s \u00e0 l\u2019eau potable (fermeture de captages), p\u00e8sent sur les finances publiques et affectent la confiance de la population dans la qualit\u00e9 de l\u2019eau. Les constats et propositions de la mission reposent sur plus de 300 auditions couvrant l\u2019ensemble des parties prenantes : \u00e9lus locaux, habitants de territoires fortement pollu\u00e9s, associations de consommateurs, associations de protection de l\u2019environnement, professionnels de la gestion de l\u2019eau. Ils s\u2019appuient \u00e9galement sur des analyses de donn\u00e9es et un benchmark international approfondi, afin de formuler des recommandations contextualis\u00e9es, r\u00e9alistes et proportionn\u00e9es.<\/p>\n
La mission observe que la majorit\u00e9 des d\u00e9passements actuels des normes de qualit\u00e9 de l\u2019eau potable est li\u00e9e \u00e0 l\u2019usage pass\u00e9 de substances d\u00e9sormais interdites. La r\u00e9duction des \u00e9missions \u00e0 la source et le renforcement de la protection des captages, bien que n\u00e9cessaires pour l\u2019avenir, ne suffiront pas \u00e0 r\u00e9tablir rapidement la conformit\u00e9 de l\u2019eau. Des investissements suppl\u00e9mentaires dans des interconnexions de r\u00e9seaux et de nouvelles usines de traitement de l\u2019eau apparaissent indispensables, avec des cons\u00e9quences financi\u00e8res \u00e0 anticiper pour les collectivit\u00e9s, les services publics de l\u2019eau et les usagers.\u00a0(contenu r\u00e9sum\u00e9 par l’IA)\u200bLire la
