PFAS in Remilly-sur-Tille's tap water: between 0.5 and 2.5 ng/L
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
PFAS-4 found at a low level
0.5 ng/L of PFAS-4 was found. The other substances were below the lab's detection limit, so the true total sits between 0.5 ng/L and 2.5 ng/L. Our benchmark of 0.5 ng/L falls inside that range, so the check cannot settle it.
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 Arc-sur-Tille, on the same distribution network as Remilly-sur-Tille (SINOTIVEAU, R. SECONDAIRE SECTEUR ARC). 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 Remilly-sur-Tille, the 4 most closely watched PFAS (PFAS-4) add up to between 0.5 ng/L and 2.5 ng/L at the latest PFAS check on 18 March 2026, because some were below the detection limit. Our 0.5 ng/L benchmark falls inside that range, so there's no verdict. Sum of 20 PFAS: 0.5 ng/L (0.0005 µg/L), below the EU legal limit (100 ng/L). Sampled in Arc-sur-Tille, on the same network. 2 checks since 24 March 2025: sum of 20 PFAS from 0.5 ng/L to 0.52 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

PFAS over time in Remilly-sur-Tille
2 PFAS checks since 24 March 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Remilly-sur-Tille.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at |
|---|---|---|---|
| 0.5 ng/L | 0.5 ng/L | Arc-sur-Tille | |
| < 2.5 ng/L · calculated | 0.52 ng/L | Remilly-sur-Tille |
Calculated values: “<” is an upper bound from published thresholds, “≥” a lower bound, “–” means no published sum or complete measurement. How to read a PFAS result

Frequently asked questions
Is tap water in Remilly-sur-Tille safe to drink?
Yes. At the check on 20 May 2026, the tap water in Remilly-sur-Tille 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 Remilly-sur-Tille's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.5 ng/L. The EU limit is 100 ng/L, so this water is at 0.5 % of the limit. (below the EU limit)
Does the water in Remilly-sur-Tille also meet the strictest limits in Europe?
Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 0.5 ng/L stays below.
Are PFAS levels rising in Remilly-sur-Tille'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 Remilly-sur-Tille?
The water hardness in Remilly-sur-Tille is 23.4 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
