Ce contrôle fait suite au prélèvement du 02/07 qui avait mis en évidence des résultats non satisfaisants (bulletin adressé par ailleurs). 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":"unknown","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=22377","license":"Licence Ouverte / Open Licence (Etalab)","kind":"api","verified":true,"retrievedAt":"2026-09-21T10:49:18.301Z","note":null},"pfas":{"status":"measured","sum20":{"value":0.0044,"valueText":"0,0044","unit":"µg/L","limit":0.1,"limitUnit":"µg/L","status":"ok","sampleDate":"2026-07-02T11:10:00Z","sampleId":"02200245937"},"pfas4":{"value":0.0017,"valueText":"0.0017","unit":"µg/L","limit":0.004,"limitUnit":"µg/L","status":"ok","sampleDate":"2026-07-02T11:10:00Z","sampleId":"02200245937"},"pfas4DetectedCount":1,"lowerBound":true,"sampledAt":null,"qualifiers":[{"name":"Acide perfluoroheptane sulfonique (PFHpS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoroheptanoïque (PFHPA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoropentanoïque (PFPEA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro undecanoïque (PFUnA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro-octanoïque (PFOA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro undecane sulfonique (PFUnDS)","valueText":"<0,001","unit":"µg/L"},{"name":"Perfluorohexane sulfonate (PFHXS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluorododécanoique (PFDoDA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluorohexanoïque (PFHXA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluorononane sulfonique (PFNS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro tridecanoique (PFTrDA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro tridecane sulfonique (PFTrDS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluorodecane sulfonique (PFDS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide sulfonique de perfluorobutane (PFBS)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoro-nonanoïque (PFNA)","valueText":"<0,001","unit":"µg/L"},{"name":"Acide perfluoropentane sulfonique (PFPS)","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"}],"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":"02200245937","date":"2026-07-02","commune":"22377","communeName":"Tréveneuc","sourceUrl":"https://hubeau.eaufrance.fr/api/v1/qualite_eau_potable/resultats_dis?code_prelevement=02200245937&size=2000","networks":["022000779"],"sum20":{"value":0.0044,"valueText":"0,0044","unit":"µg/L","nonDetect":false,"lowerBound":false},"pfas4":{"value":0.0017,"valueText":"0,0017","unit":"µg/L","nonDetect":false,"lowerBound":false},"revision":"c0e700d765dfd9444b06ab4ddd0eaafe66043bb54655338ca519192d9d7c0d7e"},{"id":"02200244567","date":"2026-04-09","commune":"22325","communeName":"Saint-Quay-Portrieux","sourceUrl":"https://hubeau.eaufrance.fr/api/v1/qualite_eau_potable/resultats_dis?code_prelevement=02200244567&size=2000","networks":["022000779"],"sum20":{"value":0.0062,"valueText":"0,0062","unit":"µg/L","nonDetect":false,"lowerBound":false},"pfas4":{"value":0.0062,"valueText":"0,0062","unit":"µg/L","nonDetect":false,"lowerBound":false},"revision":"337f7beb49dd52edeb42dadab97d1f26f3dbb7aa4a83b1f8e980eec04c2f4ef8"},{"id":"02200241874","date":"2025-09-24","commune":"22222","communeName":"Plouha","sourceUrl":"https://hubeau.eaufrance.fr/api/v1/qualite_eau_potable/resultats_dis?code_prelevement=02200241874&size=2000","networks":["022000779"],"sum20":{"value":0.0067,"valueText":"0,0067","unit":"µg/L","nonDetect":false,"lowerBound":false},"pfas4":{"value":0.0067,"valueText":"0,0067","unit":"µg/L","nonDetect":false,"lowerBound":false},"revision":"95bb1f280dfd80001d0fc47ccd74c56a782c513cdf27e51bba8835f1c85db36e"},{"id":"02200240151","date":"2025-06-16","commune":"22177","communeName":"Pléguien","sourceUrl":"https://hubeau.eaufrance.fr/api/v1/qualite_eau_potable/resultats_dis?code_prelevement=02200240151&size=2000","networks":["022000779"],"sum20":{"value":null,"valueText":"
