PFAS in the tap water of Rivarennes (Indre-et-Loire): under 10 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
No PFAS detected
The lab sees nothing below 10 ng/L, 20 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 Saint-Benoît-la-Forêt, on the same distribution network as Rivarennes (SAINT BENOIT). 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 2 to 4 ng/L upward. None reached that limit, so their total is below 10 ng/L rather than zero.

Frequently asked questions
Is tap water in Rivarennes safe to drink?
Yes. At the check on 22 April 2026, the tap water in Rivarennes was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés. A noter la présence de traces de métabolites de pesticides (Atrazine déséthyl, Atrazine déséthyl déisopropyl) à des teneurs inférieures à la valeur limite de 0,10 µg/l.”
How high are PFAS levels in Rivarennes's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at –. The EU limit is 100 ng/L, so this water is at – of the limit. (below the EU limit)
Does the water in Rivarennes also meet the strictest limits in Europe?
The check cannot say. None of the four compounds was quantified, but the laboratory's detection limits add up to 10 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.
How hard is the water in Rivarennes?
The water hardness in Rivarennes is 27.5 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
