PFAS in drinking water

None of the 4 most harmful PFAS detected

Amount found in the water < 3 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, 5.8 ng/L found in total
Our health benchmark 0.5 ng/L

The lab sees nothing below 3 ng/L, 6 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.

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.

More about this result

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

The lab detects each of the four substances from 0.5 to 1.5 ng/L upward. None reached that limit, so their total is below 3 ng/L rather than zero.

None found. The lab sees nothing below 3 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Ploërmel, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 26 May 2026. The total is below 3 ng/L, the sum of the detection limits and 6 times our 0.5 ng/L benchmark. Sum of 20 PFAS: 5.8 ng/L (0.0058 µg/L), below the EU legal limit (100 ng/L). 10 checks since 24 February 2025: PFAS-4 up to 1.3 ng/L, sometimes below the detection limit, averaging at least 0.26 ng/L over 12 months (non-detects as 0).

Frequently asked questions

Is tap water in Ploërmel safe to drink?

All the values shown here (18 June 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”

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

The total of 20 PFAS ("forever chemicals") was last measured at 5.8 ng/L. The EU limit is 100 ng/L, so this water is at 6 % of the limit. (below the EU limit)

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

As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 3 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.

Are PFAS levels rising in Ploërmel's tap water?

Too few quantified checks to say (2 since 24 February 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.

How hard is the water in Ploërmel?

The water hardness in Ploërmel is 13.8 °f (soft). 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.
