Amount found in the water 1.9 ng/L 0.0019 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 Lussac-les-Châteaux, on the same distribution network as Mazerolles (LUSSAC LE PONT). 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 Mazerolles, the 4 most closely watched PFAS (PFAS-4) add up to 1.9 ng/L (0.0019 µg/L) at the latest PFAS check on 24 July 2026. That's 3.8 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 13.7 ng/L (0.0137 µg/L), below the EU legal limit (100 ng/L). Sampled in Lussac-les-Châteaux, on the same network. 12 checks since 14 April 2025: PFAS-4 up to 4.2 ng/L, sometimes below the detection limit, averaging 2.59 ng/L over 12 months. No clear trend.

Frequently asked questions

Is tap water in Mazerolles safe to drink?

Yes. At the check on 24 July 2026, the tap water in Mazerolles was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”

How high are PFAS levels in Mazerolles's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 13.7 ng/L. The EU limit is 100 ng/L, so this water is at 14 % of the limit. (below the EU limit)

Does the water in Mazerolles also meet the strictest limits in Europe?

Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 1.9 ng/L stays below.

Are PFAS levels rising in Mazerolles's tap water?

No clear trend. Since 14 April 2025, 12 checks have been published; on the main network the PFAS-4 sum ranged between 1.1 ng/L and 4.2 ng/L (9 quantified values), at times below the detection limit. pfasnearme only reports a trend from a change of at least 25 % and 1 ng/L.

How hard is the water in Mazerolles?

The water hardness in Mazerolles is 34 °f (hard). 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 28 September 2026.
