Une mission inter-inspections, mandat\u00e9e par les minist\u00e8res sociaux, a \u00e9valu\u00e9 l\u2019ampleur des pollutions de l\u2019eau destin\u00e9e \u00e0 la consommation humaine par les PFAS et les pesticides, ainsi que les co\u00fbts potentiels associ\u00e9s. Elle propose une strat\u00e9gie d\u2019action gradu\u00e9e et territorialis\u00e9e, combinant mesures pr\u00e9ventives (r\u00e9duction des \u00e9missions \u00e0 la source, protection des captages) et mesures curatives (nouvelles interconnexions, usines de traitement), afin de prot\u00e9ger les populations tout en contenant l\u2019augmentation in\u00e9vitable du prix de l\u2019eau. Cette strat\u00e9gie repose sur une participation renforc\u00e9e des principaux \u00e9metteurs de PFAS et de pesticides au 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 potable, \u00e0 des concentrations de pesticides ou de PFAS d\u00e9passant les limites de qualit\u00e9 europ\u00e9ennes. Les restrictions de consommation de l\u2019eau du robinet pour raisons sanitaires demeurent rares, mais plusieurs facteurs laissent craindre une hausse des non-conformit\u00e9s dans les ann\u00e9es \u00e0 venir : difficult\u00e9s de mesure exhaustive des pollutions, persistance et usage continu de certaines mol\u00e9cules, extension du p\u00e9rim\u00e8tre 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 de l\u2019exposition chronique et des effets \u00ab cocktail \u00bb. Elle note \u00e9galement les cons\u00e9quences indirectes : fragilisation de l\u2019acc\u00e8s \u00e0 l\u2019eau (fermeture de captages), impact sur les finances publiques et \u00e9rosion de la confiance de la population dans l\u2019eau potable.<\/p>\n
Les d\u00e9passements actuels de normes de qualit\u00e9 sont attribu\u00e9s, pour l\u2019essentiel, \u00e0 l\u2019usage pass\u00e9 de substances aujourd\u2019hui interdites. La seule r\u00e9duction des \u00e9missions actuelles et le renforcement de la protection des captages, bien que n\u00e9cessaires pour l\u2019avenir, ne permettront pas de r\u00e9tablir rapidement la conformit\u00e9 de l\u2019eau potable. Des investissements suppl\u00e9mentaires sont jug\u00e9s indispensables pour d\u00e9velopper de nouvelles infrastructures de traitement et d\u2019interconnexion. La mission rel\u00e8ve toutefois les difficult\u00e9s importantes rencontr\u00e9es par les collectivit\u00e9s locales pour engager ces investissements.<\/p>\n
Les conclusions et propositions de la mission s\u2019appuient sur plus de 300 auditions, incluant \u00e9lus locaux, habitants de territoires fortement pollu\u00e9s, associations de consommateurs et de protection de l\u2019environnement, ainsi que professionnels de la gestion de l\u2019eau. Elles reposent sur des analyses de donn\u00e9es et un benchmark international approfondi, visant \u00e0 formuler des constats contextualis\u00e9s et des recommandations pr\u00e9sent\u00e9es comme r\u00e9alistes et proportionn\u00e9es.\u00a0(contenu r\u00e9sum\u00e9 par l’IA)\u200bLire la Suite<\/a>\u200b<\/p>","protected":false},"excerpt":{"rendered":" Une mission inter-inspections,
