Drinking water quality in Gouville-sur-Mer
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at <SEUIL µg/L. The EU limit is 0.1 µg/L, so this water is at 0 % of the limit. (19 February 2025)
This source does not list each PFAS substance separately, so we cannot compare this water with the health limit.
5 PFAS (see each substance)
| Acide perfluorododécanoique (PFDoDA) | <0,0020 µg/L |
| Acide perfluorobutanoïque (PFBA) | <0,0050 µg/L |
| Acide perfluorodecane sulfonique (PFDS) | <0,0010 µg/L |
| Acide perfluoropentane sulfonique (PFPS) | <0,0010 µg/L |
| Acide perfluoropentanoïque (PFPEA) | <0,0020 µg/L |

Official assessment
The latest official test passed all quality requirements.
„L'eau s'est révélée conforme aux limites et références de qualité pour l'ensemble des paramètres phycico-chimiques mesurés. Sur le plan microbiologique, il est à noter la présence de germes aérobies revivifiables à 22°C et à 36°C en grand nombre. Par ailleurs, certains paramètres (E.Coli et coliformestotaux) n'ont pu être lus en raison d'une flore interférente importante. L'exploitant a été informé du problème bactériologique rencontré. Un nouveau prélèvement a été réalisé afin de vérifier la qualité de l'eau distribuée.“
