PFAS in drinking water

None of the 4 most harmful PFAS detected

Amount found in the water < 4 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, 2 ng/L found in total
Our health benchmark 0.5 ng/L

The lab sees nothing below 4 ng/L, 8 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 Parcy-et-Tigny, on the same distribution network as Ambrief (UDI DE PARCY TIGNY). 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 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

None found. The lab sees nothing below 4 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Ambrief, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 23 January 2025. The total is below 4 ng/L, the sum of the detection limits and 8 times our 0.5 ng/L benchmark. Sum of 20 PFAS: 2 ng/L (0.002 µg/L), below the EU legal limit (100 ng/L). Sampled in Parcy-et-Tigny, on the same network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions

Is tap water in Ambrief safe to drink?

Yes. At the check on 22 January 2026, the tap water in Ambrief was within every limit tested. “Eau d’alimentation conforme aux limites de qualité en vigueur mais non satisfaisante à la référence de qualité pour le paramètre Carbone Organique Total. Il est demandé de remédier à la situation de non-conformité constatée. En attendant, l'eau reste consommable.”

How high are PFAS levels in Ambrief's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 2 ng/L. The EU limit is 100 ng/L, so this water is at 2 % of the limit. (below the EU limit)

Does the water in Ambrief also meet the strictest limits in Europe?

As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 4 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.

How hard is the water in Ambrief?

The water hardness in Ambrief is 53.2 °f (hard). 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 12 September 2026.

Same water network

Same distribution network as Ambrief, so in principle the same water.
