PFAS in drinking water

No PFAS detected

Amount found in the water < 4 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, none found
Our health benchmark 0.5 ng/L

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.

Sample taken in Carrépuis, on the same distribution network as Crémery (GRUNY UDI). 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 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

In Crémery, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 16 February 2026. 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: <0,029 µg/L, below the EU legal limit (100 ng/L). Sampled in Carrépuis, on the same network. 2 checks since 18 February 2025, sum of 20 PFAS always below the detection limit (29 ng/L).

PFAS over time in Crémery

2 PFAS checks since 18 February 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Crémery.

“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Calculated values: “<” is an upper bound from published thresholds, “≥” a lower bound, “–” means no published sum or complete measurement. How to read a PFAS result

Frequently asked questions

Is tap water in Crémery safe to drink?

At the latest check, the water was over at least one limit. “Eau d’alimentation non conforme aux limites de qualité en vigueur pour le paramètre nitrates. Il est demandé de remédier à la situation de non-conformité constatée. En attendant, cette eau est déconseillée aux populations sensibles (femmes enceintes, nourrissons) pour des usages alimentaires. Un suivi renforcé est mis en place.”

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

At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 29 ng/L. The EU limit is 100 ng/L, so this water is under 29 % of the limit. (below the EU limit)

Does the water in Crémery 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 Crémery's tap water?

Calculated PFAS-4 values are listed in the table. The chart uses laboratory-published sum-of-20 results; there are too few laboratory-published PFAS-4 sums for the existing trend calculation.

How hard is the water in Crémery?

The water hardness in Crémery is 41.8 °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 Crémery, so in principle the same water.
