PFAS in Plémy's tap water: under 6 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
None of the 4 most harmful PFAS detected
The lab sees nothing below 6 ng/L, 12 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.
Sample taken in Plœuc-L'Hermitage, on the same distribution network as Plémy (PLOEUC PAR RESERVOIR BOURG). 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.
The lab detects each of the four substances from 1 to 2 ng/L upward. None reached that limit, so their total is below 6 ng/L rather than zero.

None found. The lab sees nothing below 6 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Plémy, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 11 May 2026. The total is below 6 ng/L, the sum of the detection limits and 12 times our 0.5 ng/L benchmark. Sum of 20 PFAS: 2.4 ng/L (0.0024 µg/L), below the EU legal limit (100 ng/L). Sampled in Plœuc-L'Hermitage, on the same network. 9 checks since 2 April 2025: PFAS-4 up to 1.8 ng/L, sometimes below the detection limit, averaging at least 0.45 ng/L over 12 months (non-detects as 0).

Frequently asked questions
Is tap water in Plémy safe to drink?
Yes. At the check on 29 July 2026, the tap water in Plémy 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 Plémy's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 2.4 ng/L. The EU limit is 100 ng/L, so this water is at 2 % of the limit. (below the EU limit)
Does the water in Plémy also meet the strictest limits in Europe?
The check cannot say. None of the four compounds was quantified, but the laboratory's detection limits add up to 6 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.
Are PFAS levels rising in Plémy's tap water?
Too few quantified checks to say (1 since 2 April 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Plémy?
The water hardness in Plémy is 13 °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.
Same water network
Same distribution network as Plémy, so in principle the same water.
