PFAS in Louroux-Bourbonnais's tap water: 27 ng/L, 54x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
54× 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 Hérisson, on the same distribution network as Louroux-Bourbonnais (RESEAU NORD RIVE DROITE CHER). 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).

In Louroux-Bourbonnais, the 4 most closely watched PFAS (PFAS-4) add up to 27 ng/L (0.027 µg/L) at the latest PFAS check on 7 July 2026. That's 54 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 40 ng/L (0.04 µg/L), below the EU legal limit (100 ng/L). Sampled in Hérisson, on the same network. 7 checks since 8 September 2025: PFAS-4 from 19 ng/L to 27 ng/L, averaging 22.86 ng/L over 12 months. No clear trend.

Frequently asked questions
Is tap water in Louroux-Bourbonnais safe to drink?
Yes. At the check on 7 July 2026, the tap water in Louroux-Bourbonnais was within every limit tested. “Eau d'alimentation conforme aux limites de qualité pour ce qui concerne les paramètres mesurés. La référence de qualité du paramètre carbone organique total n'est pas satisfaite.”
How high are PFAS levels in Louroux-Bourbonnais's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 40 ng/L. The EU limit is 100 ng/L, so this water is at 40 % of the limit. (below the EU limit)
Does the water in Louroux-Bourbonnais also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 27 ng/L. That is 6.8 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 Louroux-Bourbonnais's tap water?
No clear trend. Since 30 May 2024, 7 checks have been published; on the main network the PFAS-4 sum ranged between 19 ng/L and 27 ng/L (7 quantified values), at times below the detection limit. pfasnearme only reports a trend from a change of at least 25 % and 1 ng/L. These history statistics use laboratory-published sums only.
How hard is the water in Louroux-Bourbonnais?
The water hardness in Louroux-Bourbonnais is 8.2 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
