PFAS in Porquéricourt's tap water: 3 ng/L, 6x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
6× above our health benchmark
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 Noyon, on the same distribution network as Porquéricourt (L'OUEST NOYONNAIS). 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.
Substances below the detection limit count as 0, so the real total may be higher.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Porquéricourt, the 4 most closely watched PFAS (PFAS-4) add up to 3 ng/L (0.003 µg/L) at the latest PFAS check on 16 March 2026. That's 6 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 13 ng/L (0.013 µg/L), below the EU legal limit (100 ng/L). Sampled in Noyon, on the same network. 3 checks since 5 December 2025: PFAS-4 from 3 ng/L to 3 ng/L, averaging 3 ng/L over 12 months. No clear trend.

Yes. At the check on 2 June 2026, the tap water in Porquéricourt 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 Porquéricourt's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 13 ng/L. The EU limit is 100 ng/L, so this water is at 13 % of the limit. (below the EU limit)
Does the water in Porquéricourt also meet the strictest limits in Europe?
Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 3 ng/L stays below.
Are PFAS levels rising in Porquéricourt's tap water?
No clear trend. Since 5 December 2025, 3 checks have been published; on the main network the PFAS-4 sum ranged between 3 ng/L and 3 ng/L (3 quantified values), at times below the detection limit. pfasnearme only reports a trend from a change of at least 25 % and 1 ng/L.
How hard is the water in Porquéricourt?
The water hardness in Porquéricourt is 21.8 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
