PFAS in drinking water

No PFAS detected

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.

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.

None found. The lab sees nothing below 4 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Marzy, 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 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). 4 checks since 16 September 2025: PFAS-4 up to 8 ng/L, sometimes below the detection limit.

PFAS over time in Marzy

4 PFAS checks since 16 September 2025, values as published. Samples from 2 communes on the same network: it's the same water, so each one applies to Marzy. Samples come from 2 distribution networks. The trend refers to the network “FOURCHAMBAULT”.

Frequently asked questions

Is tap water in Marzy safe to drink?

Yes. At the check on 23 July 2026, the tap water in Marzy was within every limit tested. “La teneur en chlore est insuffisante pour garantir une désinfection ef ficace de l’eau distribuée sur l’ensemble du réseau. Il est recommandé de maintenir au moins 0,1 mg/L en tout point du réseau. Les autres p aramètres mesurés répondent aux normes de potabilité.”

How high are PFAS levels in Marzy'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 Marzy 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 Marzy's tap water?

Too few quantified checks to say (2 since 16 September 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.

How hard is the water in Marzy?

The water hardness in Marzy is 34.4 °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 Marzy, so in principle the same water.
