PFAS in Anctoville-sur-Boscq's tap water: 4.4 ng/L, 8.8x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
8.8× 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 Saint-Planchers, on the same distribution network as Anctoville-sur-Boscq (GRANVILLE ST NICOLAS). 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 Anctoville-sur-Boscq, the 4 most closely watched PFAS (PFAS-4) add up to 4.4 ng/L (0.0044 µg/L) at the latest PFAS check on 29 April 2026. That's 8.8 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 5.4 ng/L (0.0054 µg/L), below the EU legal limit (100 ng/L). Sampled in Saint-Planchers, on the same network. 4 checks since 16 April 2025: sum of 20 PFAS up to 5.4 ng/L, sometimes below the detection limit.

Details and sources
PFAS over time in Anctoville-sur-Boscq
4 PFAS checks since 16 April 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Anctoville-sur-Boscq.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at |
|---|---|---|---|
| 4.4 ng/L – < 7.4 ng/L · calculated | 5.4 ng/L | Saint-Planchers | |
| < 4 ng/L · calculated | 1.4 ng/L | Granville | |
| < 4 ng/L · calculated | < detection limit | Granville | |
| < 6 ng/L · calculated | < detection limit | Granville |
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 Anctoville-sur-Boscq safe to drink?
Yes. At the check on 29 April 2026, the tap water in Anctoville-sur-Boscq was within every limit tested. “Eau d'alimentation conforme aux limites et références de qualité pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in Anctoville-sur-Boscq's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 5.4 ng/L. The EU limit is 100 ng/L, so this water is at 5 % of the limit. (below the EU limit)
Does the water in Anctoville-sur-Boscq also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 4.4 ng/L. That is 1.1 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The water still passes the current EU legal limit (100 ng/L for the total of 20 PFAS).
Are PFAS levels rising in Anctoville-sur-Boscq'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 Anctoville-sur-Boscq?
The water hardness in Anctoville-sur-Boscq is 14.2 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
