Des dépassements ont été observés pour plusieurs paramètres : les pesticides dépassent l’exigence réglementaire de 0,1 µg/l sans atteindre les valeurs imposant une restriction des usages sanitaires ; la teneur en FLUORURES dépasse la limite de qualité de 1 500 µg/l pour le forage F2002, tandis que les NITRATES sont supérieurs à la limite de qualité fixée à 50 mg/l pour le forage F1964. Un contrôle renforcé est en place et des actions correctives sont engagées par l’exploitant pour rétablir la qualité de l’eau. Compte tenu de l’utilisation alternée des forages, l’eau ne doit pas être consommée par les nourrissons et les femmes enceintes et est déconseillée pour les enfants de moins de 12 ans. Enfin, on note une valeur de CHLORE LIBRE élevée. La concentration en chlore devra être maintenue inférieure à 0,5 mg/l sur le réseau de distribution.","bacteriological":"conform","chemical":"not_conform"},"source":{"name":"Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM)","url":"https://hubeau.eaufrance.fr/api/v1/qualite_eau_potable/resultats_dis?code_commune=51489","license":"Licence Ouverte / Open Licence (Etalab)","kind":"api","verified":true,"retrievedAt":"2026-09-12T14:57:27.216Z","note":null},"pfas":{"status":"measured","sum20":{"value":null,"valueText":"<0,028","unit":"µg/L","limit":0.1,"limitUnit":"µg/L","status":"ok","sampleDate":"2025-06-24T12:15:00Z","sampleId":"05100142172","nonDetect":true,"upperBound":0.028},"pfas4":{"value":null,"valueText":"<0,004","unit":"µg/L","limit":0.004,"limitUnit":"µg/L","status":"ok","sampleDate":"2025-06-24T12:15:00Z","sampleId":"05100142172","nonDetect":true,"upperBound":0.004},"pfas4DetectedCount":0,"lowerBound":true,"sampledAt":null,"qualifiers":[{"name":"Acide perfluoro tridecane sulfonique (PFTrDS)","valueText":"<0,005","unit":"µg/L"},{"name":"Acide perfluorononane sulfonique (PFNS)","valueText":"<0,002","unit":"µg/L"},{"name":"Acide perfluoroheptanoïque (PFHPA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro-decanoïque (PFDA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluorododécane sulfonique (PFDoDS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoropentane sulfonique (PFPS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro-nonanoïque (PFNA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide sulfonique de perfluorobutane (PFBS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluorodecane sulfonique (PFDS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro undecanoïque (PFUnA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoroheptane sulfonique (PFHpS)","valueText":"<0,002","unit":"µg/L"},{"name":"Acide sulfonique de perfluorooctane (PFOS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluorohexanoïque (PFHXA)","valueText":"<0,002","unit":"µg/L"},{"name":"Acide perfluoro undecane sulfonique (PFUnDS)","valueText":"<0,002","unit":"µg/L"},{"name":"Acide perfluoro tridecanoique (PFTrDA)","valueText":"<0,001","unit":"µg/L"},{"name":"Perfluorohexane sulfonate (PFHXS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro-octanoïque (PFOA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoropentanoïque (PFPEA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluorododécanoique (PFDoDA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluorobutanoïque (PFBA)","valueText":"<0,001","unit":"µg/L"}],"comparison":{"proposed":{"value":0.0005,"period":"annual_mean","official":false,"state":"inconclusive"},"sweden":{"value":0.004,"jurisdiction":"se"},"franceSum20":{"value":0.1,"jurisdiction":"fr"}}},"samples":[{"id":"05100142172","date":"2025-06-24","commune":"51489","communeName":"Saint-Jean-devant-Possesse","sourceUrl":"https://hubeau.eaufrance.fr/api/v1/qualite_eau_potable/resultats_dis?code_prelevement=05100142172&size=2000","networks":["051000694"],"sum20":{"value":null,"valueText":"<0,028","unit":"µg/L","nonDetect":true,"lowerBound":false},"pfas4":{"value":0,"valueText":"0","unit":"µg/L","nonDetect":false,"lowerBound":true,"origin":"calculated","upperBound":0.004,"qualifiers":[{"name":"PFOA","valueText":"<0,001","unit":"µg/L"},{"name":"PFOS","valueText":"<0,001","unit":"µg/L"},{"name":"PFNA","valueText":"<0,001","unit":"µg/L"},{"name":"PFHxS","valueText":"<0,001","unit":"µg/L"}]},"revision":"b70d9209bf2530503911038fc38a4ec7872dabb902f7c8c3d3449a754c0b1652"}],"revision":"c9f054b50e100361534dc40ce761055c9d846d10724dece69400c146b519eebc"}
