PFAS in Squiffiec's tap water: 2.3 ng/L, 4.6x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
4.6× 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 Cavan, on the same distribution network as Squiffiec (PAR RESERVOIR ENTERRE DE LA JUSTICE). 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 Squiffiec, the 4 most closely watched PFAS (PFAS-4) add up to 2.3 ng/L (0.0023 µg/L) at the latest PFAS check on 26 June 2026. That's 4.6 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 4.1 ng/L (0.0041 µg/L), below the EU legal limit (100 ng/L). Sampled in Cavan, on the same network. 4 checks since 14 May 2025: PFAS-4 up to 5.3 ng/L, sometimes below the detection limit, averaging 3.2 ng/L over 12 months. No clear trend.

Frequently asked questions
Is tap water in Squiffiec safe to drink?
Yes. At the check on 26 June 2026, the tap water in Squiffiec was within every limit tested. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité pour le parmaètre équilibre calco carbonique. L'étude de l'équilibre calco-carbonique met en évidence une eau agressive. L'agressivité de l'eau peut entraîner une corrosion de certaines canalisations ainsi que des appareils ménagers (donc leur vieillissement prématuré). D'un point de vue sanitaire, cette agressivité peut présenter un risque en cas de canalisations ou de branchements en plomb.”
How high are PFAS levels in Squiffiec's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 4.1 ng/L. The EU limit is 100 ng/L, so this water is at 4 % of the limit. (below the EU limit)
Does the water in Squiffiec 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 2.3 ng/L stays below.
Are PFAS levels rising in Squiffiec's tap water?
No clear trend. Since 14 May 2025, 4 checks have been published; on the main network the PFAS-4 sum ranged between 2 ng/L and 5.3 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 Squiffiec?
The water hardness in Squiffiec is 11 °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 21 September 2026.
