PFAS in Roggenhouse's tap water: 7 ng/L, 14x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
14× 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 Munchhouse, on the same distribution network as Roggenhouse (S.I.A.E.P. MUNCHHOUSE ET ENV). 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 Roggenhouse, the 4 most closely watched PFAS (PFAS-4) add up to 7 ng/L (0.007 µg/L) at the latest PFAS check on 2 July 2025. That's 14 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 7 ng/L (0.007 µg/L), below the EU legal limit (100 ng/L). Sampled in Munchhouse, on the same network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions
Is tap water in Roggenhouse safe to drink?
At the latest check, the water was over at least one limit. “Eau d'alimentation non-conforme aux exigences de qualité. Eau d'alimentation ne répondant pas à la limite de qualité réglementaire pour un ou plusieurs paramètres bactériologiques analysés. Faible contamination microbiologique. Il appartient au distributeur d'eau de mettre en place les mesures correctives nécessaires afin de rétablir la qualité de l'eau. Des analyses de recontrôle sont commandées pour vérifier le retour à une situation normale. La température de l'eau dépasse la référence de qualité.”
How high are PFAS levels in Roggenhouse's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 7 ng/L. The EU limit is 100 ng/L, so this water is at 7 % of the limit. (below the EU limit)
Does the water in Roggenhouse also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 7 ng/L. That is 1.75 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).
How hard is the water in Roggenhouse?
The water hardness in Roggenhouse is 19.7 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
