PFAS in La Côte-Saint-André's tap water: 2 ng/L, 4x our 0.5 ng/L benchmark

PFAS in drinking water

4× above our health benchmark

Amount found in the water 2 ng/L 0.002 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 Penol, on the same distribution network as La Côte-Saint-André (LA COTE ST ANDRE SERVICE OUEST). 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 La Côte-Saint-André, the 4 most closely watched PFAS (PFAS-4) add up to 2 ng/L (0.002 µg/L) at the latest PFAS check on 22 July 2026. That's 4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 5 ng/L (0.005 µg/L), below the EU legal limit (100 ng/L). Sampled in Penol, on the same network. 2 checks since 27 May 2026: PFAS-4 from 1 ng/L to 2 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

PFAS over time in La Côte-Saint-André

6 PFAS checks since 5 May 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to La Côte-Saint-André. Samples come from 4 distribution networks. The trend refers to the network “LA COTE ST ANDRE SERVICE EST”.

“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 La Côte-Saint-André safe to drink?

Yes. At the check on 24 July 2026, the tap water in La Côte-Saint-André 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 La Côte-Saint-André's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 5 ng/L. The EU limit is 100 ng/L, so this water is at 5 % of the limit. (below the EU limit)

Does the water in La Côte-Saint-André 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 2 ng/L stays below.

Are PFAS levels rising in La Côte-Saint-André's tap water?

Too few quantified checks to say (1 since 5 May 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 La Côte-Saint-André?

The water hardness in La Côte-Saint-André is 30.1 °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 21 September 2026.

Same water network

Same distribution network as La Côte-Saint-André, so in principle the same water.
