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 Ham, on the same distribution network as Sancourt (SANCOURT UDI). 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.

In Sancourt, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 16 June 2026. 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).

Frequently asked questions

Is tap water in Sancourt safe to drink?

At the latest check, the water was over at least one limit. “Eau d'alimentation non conforme aux limites de qualité en vigueur pour le paramètre pesticide chlorothalonil R417888. Toutefois, cette eau est propre à la consommation humaine car la concentration du pesticide reste inférieure aux valeurs sanitaires. Un contrôle renforcé est mis en place.”

How high are PFAS levels in Sancourt'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 Sancourt 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 Sancourt?

The water hardness in Sancourt is 43.4 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
