PFAS in Pordic's tap water: 2.9 ng/L, 5.8x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
5.8× 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 Plérin, on the same distribution network as Pordic (PAR RESERVOIR DU SEPULCRE). 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).
More PFAS than in 88% of the cities we track

In Pordic, the 4 most closely watched PFAS (PFAS-4) add up to 2.9 ng/L (0.0029 µg/L) at the latest PFAS check on 26 May 2026. That's 5.8 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 18 ng/L (0.018 µg/L), below the EU legal limit (100 ng/L). Sampled in Plérin, on the same network. 4 checks since 14 May 2025: PFAS-4 up to 6.7 ng/L, sometimes below the detection limit, averaging at least 3.2 ng/L over 12 months (non-detects as 0).

PFAS over time in Pordic
4 PFAS checks since 14 May 2025, values as published. Samples from 3 communes on the same network: it's the same water, so each one applies to Pordic. Samples come from 2 distribution networks. The trend refers to the network “PAR RESERVOIR DU SEPULCRE”.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at | Network |
|---|---|---|---|---|
| 2.9 ng/L | 18 ng/L | Plérin | PAR RESERVOIR DU SEPULCRE | |
| 6.7 ng/L | 6.7 ng/L | Plouha | PORDIC (HORS ZONE SUD), PAR RESERVOIR DU SEPULCRE | |

Frequently asked questions
Is tap water in Pordic safe to drink?
Yes. At the check on 2 July 2026, the tap water in Pordic was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés. Cependant, les analyses réalisées montrent la présence de germes indésirables, pouvant être accidentelle, et la quasi absence de désinfectant résiduel (objectif : 0,1 mg/l de chlore libre). Ces résultats étaient signalés à l'exploitant (message du 06/07), pour vérifications d'usage, dès connaissance de ceux-ci par mes services. Il convient de vérifier les installations de désinfection afin d'assurer la présence de désinfectant en tout point du réseau. Un nouveau prélèvement de contrôle a été programmé.”
How high are PFAS levels in Pordic's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 18 ng/L. The EU limit is 100 ng/L, so this water is at 18 % of the limit. (below the EU limit)
Does the water in Pordic 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 2.9 ng/L stays below.
Are PFAS levels rising in Pordic's tap water?
Too few quantified checks to say (2 since 14 May 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Pordic?
The water hardness in Pordic is 12 °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.
