Les analyses réalisées ont mis en évidence la présence notable de chlorates. La valeur la plus faible possible de ce paramètre doit être visée sans pour autant compromettre la désinfection. La réglementation fixe une limite de qualité à 700 µg/l lorsqu'une méthode de désinfection des eaux destinées à la consommation humaine qui génère des chlorates est utilisée. Au delà de cette valeur, il est recommandé de ne pas consommer cette eau, une restriction d'usage est nécessaire. La présence de chlorates peut avoir pour origine la présence d'impuretés dans le désinfectant employé (javel, hypochlorite de calcium ...), dans ce cas la limite de qualité est fixée à 250 µg/l. Il convient, pour respecter cette exigence, de veiller à la pureté des réactifs employés ainsi qu'à leur condition de stockage et d'emploi (dosage, utilisation sous 3 mois après la livraison). Compte tenu de la teneur mesurée en chlorates sur ce prélèvement, un suivi renforcé sera mis en place sur ce paramètre.","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=22016","license":"Licence Ouverte / Open Licence (Etalab)","kind":"api","verified":true,"retrievedAt":"2026-09-21T10:49:18.301Z","note":null},"pfas":{"status":"measured","sum20":{"value":0.0081,"valueText":"0,0081","unit":"µg/L","limit":0.1,"limitUnit":"µg/L","status":"ok","sampleDate":"2026-07-22T11:35:00Z","sampleId":"02200246376"},"pfas4":{"value":0.0011,"valueText":"0.0011","unit":"µg/L","limit":0.004,"limitUnit":"µg/L","status":"ok","sampleDate":"2026-07-22T11:35:00Z","sampleId":"02200246376"},"pfas4DetectedCount":1,"lowerBound":true,"sampledAt":null,"qualifiers":[{"name":"Perfluorohexane sulfonate (PFHXS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoroheptane sulfonique (PFHpS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro-nonanoïque (PFNA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluorododécanoique (PFDoDA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoropentanoïque (PFPEA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoroheptanoïque (PFHPA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluorodecane sulfonique (PFDS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro-decanoïque (PFDA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide sulfonique de perfluorobutane (PFBS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoropentane sulfonique (PFPS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro-octanoïque (PFOA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro tridecane sulfonique (PFTrDS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro tridecanoique (PFTrDA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluorododécane sulfonique (PFDoDS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro undecanoïque (PFUnA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro undecane sulfonique (PFUnDS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluorononane sulfonique (PFNS)","valueText":"<0,001","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":"02200246376","date":"2026-07-22","commune":"22016","communeName":"Île-de-Bréhat","sourceUrl":"https://hubeau.eaufrance.fr/api/v1/qualite_eau_potable/resultats_dis?code_prelevement=02200246376&size=2000","networks":["022004122"],"sum20":{"value":0.0081,"valueText":"0,0081","unit":"µg/L","nonDetect":false,"lowerBound":false},"pfas4":{"value":0.0011,"valueText":"0,0011","unit":"µg/L","nonDetect":false,"lowerBound":false},"revision":"a853e6e8673a14944c1c3b922198ddccec4e7c72dd6b1865dcbd90fa7c035dcf"},{"id":"02200244031","date":"2026-03-04","commune":"22390","communeName":"Yvias","sourceUrl":"https://hubeau.eaufrance.fr/api/v1/qualite_eau_potable/resultats_dis?code_prelevement=02200244031&size=2000","networks":["022004122"],"sum20":{"value":0.0648,"valueText":"0,0648","unit":"µg/L","nonDetect":false,"lowerBound":false},"pfas4":{"value":0.0593,"valueText":"0,0593","unit":"µg/L","nonDetect":false,"lowerBound":false},"revision":"06e33514aa5ad5cfefb803f9bdc3a973adbd07663d71eee82bd6b74474186293"}],"revision":"74a266c4a1fb4aee0443a52877ccf295479caddc49b4df6b4711811c41224649"}
