PFAS in La Chapelle-Saint-Luc's tap water: 18 ng/L, 36x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
36× 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.
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 La Chapelle-Saint-Luc, the 4 most closely watched PFAS (PFAS-4) add up to 18 ng/L (0.018 µg/L) at the latest PFAS check on 28 May 2026. That's 36 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 21 ng/L (0.021 µg/L), below the EU legal limit (100 ng/L). 5 checks since 13 March 2025: PFAS-4 up to 12 ng/L, sometimes below the detection limit, averaging at least 7.4 ng/L over 12 months (non-detects as 0). No clear trend. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions
Is tap water in La Chapelle-Saint-Luc safe to drink?
Yes. At the check on 29 July 2026, the tap water in La Chapelle-Saint-Luc was within every limit tested. “Compte tenu des paramètres contrôlés, cette eau est conforme aux limites et références de qualité des eaux destinées à la consommation humaine, définies par l'arrêté du 11 janvier 2007, pour l'ensemble des paramètres mesurés. Néanmoins, la teneur en nitrates est élevée mais conforme à la limite de qualité fixée à 50 mg/l. Il convient de maintenir une surveillance particulière de ce paramètre. Il est à noter une teneur en chlore libre trop élevée. La teneur en chlore libre sur le réseau de distribution doit être de l'ordre de 0,1 mg/l.”
How high are PFAS levels in La Chapelle-Saint-Luc's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 21 ng/L. The EU limit is 100 ng/L, so this water is at 21 % of the limit. (below the EU limit)
Does the water in La Chapelle-Saint-Luc also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 18 ng/L. That is 4.5 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 La Chapelle-Saint-Luc's tap water?
No clear trend. Since 13 February 2025, 5 checks have been published; on the main network the PFAS-4 sum ranged between 7 ng/L and 12 ng/L (4 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 La Chapelle-Saint-Luc?
The water hardness in La Chapelle-Saint-Luc is 24.4 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
