PFAS in drinking water

28× above our health benchmark

Amount found in the water 14 ng/L 0.014 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

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.

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).

In Bourges, the 4 most closely watched PFAS (PFAS-4) add up to 14 ng/L (0.014 µg/L) at the latest PFAS check on 3 July 2026. That's 28 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 33 ng/L (0.033 µg/L), below the EU legal limit (100 ng/L). 12 checks since 11 September 2024: sum of 20 PFAS from 1 ng/L to 33 ng/L.

PFAS over time in Bourges

12 PFAS checks since 11 September 2024, from the published measurements. Samples come from 2 distribution networks. The trend refers to the network “MÉLANGE SAINT 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 Bourges safe to drink?

Yes. At the check on 24 July 2026, the tap water in Bourges was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”

How high are PFAS levels in Bourges'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 Bourges 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 Bourges'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 Bourges?

The water hardness in Bourges is 24 °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.
