PFAS in Saint-Mary-le-Plain's tap water: under 4 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
No PFAS detected
The lab sees nothing below 4 ng/L, 8 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 1 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

In Saint-Mary-le-Plain, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 27 October 2025. The total is below 4 ng/L, the sum of the detection limits and 8 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,071 µg/L, below the EU legal limit (100 ng/L). 2 checks since 9 July 2025, PFAS-4 always below the detection limit (4 ng/L).

“<” means not detected, the figure being the detection limit. “–” means not published. Labs have only reported the PFAS-4 sum (SANDRE code 9268) since autumn 2025. How to read a PFAS result
What the latest check found
At the latest check, the water was over at least one limit.
Values to watch
These results are close to their legal limit, or over it.
Outside a reference value: Coliform bacteria 2 n/(100mL) on 27 April 2026 (reference ≤ 0 mL)). These are indicator parameters with reference values, not legal limits.

Frequently asked questions
Is tap water in Saint-Mary-le-Plain safe to drink?
At the latest check, the water was over at least one limit. “Bactériologie non conforme. Eau de qualité sanitaire non satisfaisante. La mise en oeuvre de mesures correctives a été immédiatement demandée au responsable de la distribution.”
How high are PFAS levels in Saint-Mary-le-Plain's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 71 ng/L. The EU limit is 100 ng/L, so this water is under 71 % of the limit. (below the EU limit)
Does the water in Saint-Mary-le-Plain 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 4 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 Saint-Mary-le-Plain's tap water?
Too few quantified checks to say (0 since 9 July 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Saint-Mary-le-Plain?
The water hardness in Saint-Mary-le-Plain is 10.5 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
