PFAS in Saint-Doulchard's tap water: 14 ng/L, 28x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
28× 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 Bourges, on the same distribution network as Saint-Doulchard (MÉLANGE SAINT URSIN/HERRY). 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).

PFAS over time in Saint-Doulchard
22 PFAS checks since 11 July 2024, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Saint-Doulchard. Samples come from 2 distribution networks. The trend refers to the network “ST DOULCHARD PRÉDÉ/ST URSIN/HERRY”.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions
Is tap water in Saint-Doulchard safe to drink?
Yes. At the check on 3 July 2026, the tap water in Saint-Doulchard was within every limit tested. “Eau conforme aux limites de qualité, mais dépassant la référence de qualité des eaux destinées à l'alimentation humaine en ce qui concerne la numération des germes totaux et la température de l'eau.”
How high are PFAS levels in Saint-Doulchard's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 33 ng/L. The EU limit is 100 ng/L, so this water is at 33 % of the limit. (below the EU limit)
Does the water in Saint-Doulchard also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 14 ng/L. That is 3.5 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 Saint-Doulchard'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 Saint-Doulchard?
The water hardness in Saint-Doulchard is 25.4 °f (medium). 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.
