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 Larochemillay, on the same distribution network as Millay (RESEAU DE LUZY). 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.

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

In Millay, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 26 January 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 Larochemillay, on the same network. 2 checks since 26 January 2026, PFAS-4 always below the detection limit (4 ng/L).

PFAS over time in Millay

4 PFAS checks since 5 May 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Millay.

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

Frequently asked questions

Is tap water in Millay safe to drink?

Yes. At the check on 20 March 2026, the tap water in Millay was within every limit tested. Outside a reference value: pH 9.7 unité pH on 20 March 2026 (reference 6.5–9 unité pH), Electrical conductivity 90 µS/cm on 20 March 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “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. Le PH est inf érieur à la référence réglementaire de 6.5 unité pH. Il favorise la di ssolution des métaux des canalisations et des robinets. Les autres par amètres mesurés répondent aux normes de potabilité, excepté la conduct ivité.”

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

Too few quantified checks to say (0 since 5 May 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.

How hard is the water in Millay?

The water hardness in Millay is 3.3 °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 12 September 2026.

Same water network

Same distribution network as Millay, so in principle the same water.
