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 Mérenvielle, on the same distribution network as Bellegarde-Sainte-Marie (SIE GIROU HERS SAVE CADOURS). 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).

In Bellegarde-Sainte-Marie, the 4 most closely watched PFAS (PFAS-4) add up to 21 ng/L (0.021 µg/L) at the latest PFAS check on 18 June 2026. That's 42 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 26 ng/L (0.026 µg/L), below the EU legal limit (100 ng/L). Sampled in Mérenvielle, on the same network. 3 checks since 9 February 2026: PFAS-4 up to 21 ng/L, sometimes below the detection limit, averaging at least 7 ng/L over 12 months (non-detects as 0).

PFAS over time in Bellegarde-Sainte-Marie

6 PFAS checks since 5 August 2025, from the published measurements. Samples from 4 communes on the same network: it's the same water, so each one applies to Bellegarde-Sainte-Marie.

“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions

Is tap water in Bellegarde-Sainte-Marie safe to drink?

Yes. At the check on 18 June 2026, the tap water in Bellegarde-Sainte-Marie was within every limit tested. “Eau d'alimentation non conforme aux exigences de qualité en vigueur. E au incrustante.”

How high are PFAS levels in Bellegarde-Sainte-Marie's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 26 ng/L. The EU limit is 100 ng/L, so this water is at 26 % of the limit. (below the EU limit)

Does the water in Bellegarde-Sainte-Marie also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 21 ng/L. That is 5.3 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The water still passes the current EU legal limit (100 ng/L for the total of 20 PFAS).

Are PFAS levels rising in Bellegarde-Sainte-Marie's tap water?

Too few quantified checks to say (1 since 5 August 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.

How hard is the water in Bellegarde-Sainte-Marie?

The water hardness in Bellegarde-Sainte-Marie is 15.4 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?

All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 21 September 2026.
