PFAS in drinking water

No PFAS detected

Amount found in the water < 6 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 6 ng/L, 12 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 Crocq, on the same distribution network as Saint-Oradoux-près-Crocq (CROCQ BASVILLE). 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 to 2 ng/L upward. None reached that limit, so their total is below 6 ng/L rather than zero.

None found. The lab sees nothing below 6 ng/L, so our 0.5 ng/L benchmark cannot be checked.

Frequently asked questions

Is tap water in Saint-Oradoux-près-Crocq safe to drink?

Yes. At the check on 19 March 2026, the tap water in Saint-Oradoux-près-Crocq was within every limit tested. Outside a reference value: pH 5.9 unité pH on 19 March 2026 (reference 6.5–9 unité pH), Electrical conductivity 52 µS/cm on 19 March 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau d'alimentation conforme aux exigences de qualité définies par le Code de la Santé Publique, pour les paramètres mesurés au moment du prélèvement, à l’exception du paramètre conductivité. Cette eau très peu minéralisée, corrosive pour les métaux, nécessite un traitement de neutralisation.”

How high are PFAS levels in Saint-Oradoux-près-Crocq's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at –. The EU limit is 100 ng/L, so this water is at – of the limit. (below the EU limit)

Does the water in Saint-Oradoux-près-Crocq also meet the strictest limits in Europe?

The check cannot say. None of the four compounds was quantified, but the laboratory's detection limits add up to 6 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.

How hard is the water in Saint-Oradoux-près-Crocq?

The water hardness in Saint-Oradoux-près-Crocq is 1.3 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
