PFAS in Saint-Jean-de-Ceyrargues's tap water: 5 ng/L, 10x our 0.5 ng/L benchmark

PFAS in drinking water

10× above our health benchmark

Amount found in the water 5 ng/L 0.005 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

0.5 ng/L is our benchmark, not an official limit. Same EFSA method as Sweden, Denmark and the Netherlands, but stricter. It's a yearly average, compared here with the latest check.

Sample taken in Saint-Césaire-de-Gauzignan, on the same distribution network as Saint-Jean-de-Ceyrargues (EUZET-MARTIGNAR-NERS-STCESAIRE-STETIENNEOM-STHIPPOCAT-STJEANCEY STMAURICECA). The health authority samples one tap per network; a network carries the same treated water everywhere.

More about this result

The US also limits PFOA and PFOS to 4 ng/L each, per substance.

Substances below the detection limit count as 0, so the real total may be higher.

One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).
