Les analyses réalisées ont cependan t mis en évidence la présence importante de chlorates. La réglementati on fixe une limite de qualité à 700 µg/l pour ce paramètre, lorsqu'une méthode de désinfection des eaux destinées à la consommation humaine qui en génére est utilisée. Au delà de cette valeur, il est recommand é de ne pas consommer cette eau, une restriction d'usage est nécessair e. La valeur la plus faible possible de ce paramètre doit être visée s ans pour autant compromettre  la désinfection. Compte tenu de la teneu r mesurée en chlorates sur ce prélèvement, un suivi renforcé sera mis en place sur ce paramètre. Par ailleurs, des traces de pesticides (don t l'ethephon, régulateur de croissance) peut-être observée dans le cad re de ce contrôle.","bacteriological":"conform","chemical":"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=35019","license":"Licence Ouverte / Open Licence (Etalab)","kind":"api","verified":true,"retrievedAt":"2026-09-21T10:50:12.868Z","note":null},"pfas":{"status":"measured","sum20":{"value":0.0141,"valueText":"0,01410","unit":"µg/L","limit":0.1,"limitUnit":"µg/L","status":"ok","sampleDate":"2026-07-08T11:14:00Z","sampleId":"03500180330"},"pfas4":{"value":0.00465,"valueText":"0.00465","unit":"µg/L","limit":0.004,"limitUnit":"µg/L","status":"exceeded","sampleDate":"2026-07-08T11:14:00Z","sampleId":"03500180330"},"pfas4DetectedCount":2,"lowerBound":true,"sampledAt":null,"qualifiers":[{"name":"Acide perfluoro tridecanoique (PFTrDA)","valueText":"<0,0010","unit":"µg/L"},{"name":"Acide perfluoro-decanoïque (PFDA)","valueText":"<0,0010","unit":"µg/L"},{"name":"Acide perfluoro tridecane sulfonique (PFTrDS)","valueText":"<0,00040","unit":"µg/L"},{"name":"Acide perfluorodecane sulfonique (PFDS)","valueText":"<0,00040","unit":"µg/L"},{"name":"Acide perfluorododécanoique (PFDoDA)","valueText":"<0,0010","unit":"µg/L"},{"name":"Acide perfluoroheptane sulfonique (PFHpS)","valueText":"<0,00040","unit":"µg/L"},{"name":"Acide perfluoro-octanoïque (PFOA)","valueText":"<0,0010","unit":"µg/L"},{"name":"Acide perfluoro-nonanoïque (PFNA)","valueText":"<0,0010","unit":"µg/L"},{"name":"Acide perfluoro undecanoïque (PFUnA)","valueText":"<0,0010","unit":"µg/L"},{"name":"Acide perfluoro undecane sulfonique (PFUnDS)","valueText":"<0,00040","unit":"µg/L"},{"name":"Acide perfluoropentane sulfonique (PFPS)","valueText":"<0,00040","unit":"µg/L"},{"name":"Acide perfluorononane sulfonique (PFNS)","valueText":"<0,00040","unit":"µg/L"},{"name":"Acide perfluorododécane sulfonique (PFDoDS)","valueText":"<0,00040","unit":"µg/L"},{"name":"Acide perfluoropentanoïque (PFPEA)","valueText":"<0,0050","unit":"µg/L"}],"comparison":{"proposed":{"value":0.0005,"period":"annual_mean","official":false,"state":"over"},"sweden":{"value":0.004,"jurisdiction":"se"},"franceSum20":{"value":0.1,"jurisdiction":"fr"}}},"samples":[{"id":"03500180330","date":"2026-07-08","commune":"35019","communeName":"Bazouges-la-Pérouse","sourceUrl":"https://hubeau.eaufrance.fr/api/v1/qualite_eau_potable/resultats_dis?code_prelevement=03500180330&size=2000","networks":["035000026"],"sum20":{"value":0.0141,"valueText":"0,01410","unit":"µg/L","nonDetect":false,"lowerBound":false},"pfas4":{"value":0.00465,"valueText":"0,00465","unit":"µg/L","nonDetect":false,"lowerBound":false},"revision":"cdf6aefd19148c3873a3c846a0ca5e087201c71dcf9e16813db363bf475c3e78"},{"id":"03500178822","date":"2026-03-24","commune":"35004","communeName":"Val-Couesnon","sourceUrl":"https://hubeau.eaufrance.fr/api/v1/qualite_eau_potable/resultats_dis?code_prelevement=03500178822&size=2000","networks":["035000026"],"sum20":{"value":0.0026,"valueText":"0,00260","unit":"µg/L","nonDetect":false,"lowerBound":false},"pfas4":{"value":0.0026,"valueText":"0,00260","unit":"µg/L","nonDetect":false,"lowerBound":false},"revision":"09c46abfc890298382ca504e6945feb8e70d56774d7ad8691a103cffae0f35e7"},{"id":"03500176921","date":"2025-10-15","commune":"35004","communeName":"Val-Couesnon","sourceUrl":"https://hubeau.eaufrance.fr/api/v1/qualite_eau_potable/resultats_dis?code_prelevement=03500176921&size=2000","networks":["035000026"],"sum20":{"value":0.01321,"valueText":"0,01321","unit":"µg/L","nonDetect":false,"lowerBound":false},"pfas4":{"value":0.00656,"valueText":"0,00656","unit":"µg/L","nonDetect":false,"lowerBound":false},"revision":"fa5949f22c07ffc5de5a1d7da9b8afa7b6ef03e74a92fe6424d722a6e4cc8968"},{"id":"03500173308","date":"2025-02-24","commune":"35004","communeName":"Val-Couesnon","sourceUrl":"https://hubeau.eaufrance.fr/api/v1/qualite_eau_potable/resultats_dis?code_prelevement=03500173308&size=2000","networks":["035000026"],"sum20":{"value":0.0018,"valueText":"0,00180","unit":"µg/L","nonDetect":false,"lowerBound":false},"pfas4":{"value":0.0018,"valueText":"0.0018","unit":"µg/L","nonDetect":false,"lowerBound":true,"origin":"calculated","upperBound":0.0038,"qualifiers":[{"name":"PFOA","valueText":"<0,0010","unit":"µg/L"},{"name":"PFNA","valueText":"<0,0010","unit":"µg/L"}]},"revision":"a7bde2448668cfd3a263cd68f0a6d364c56c2148c1ce1aaf8f4ebe2db1e956ad"}],"revision":"69d04d3ad3324c2d160840be6e2382f4ae1c7e0d2034a26f1a5fa166c7b211cf"}
