PFAS in Belin-Béliet's tap water: under 6 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 6 ng/L, 12 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 Le Barp, on the same distribution network as Belin-Béliet (LE BARP). 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 1 to 2 ng/L upward. None reached that limit, so their total is below 6 ng/L rather than zero.

In Belin-Béliet, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 24 June 2026. The total is below 6 ng/L, the sum of the detection limits and 12 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). Sampled in Le Barp, on the same network. 6 checks since 10 April 2025, sum of 20 PFAS always below the detection limit. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).
Details and sources
PFAS over time in Belin-Béliet
6 PFAS checks since 10 April 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Belin-Béliet. Samples come from 2 distribution networks. The trend refers to the network “LE BARP”.
“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 | Network |
|---|---|---|---|---|
| < 6 ng/L · calculated | < detection limit | Le Barp | LE BARP | |
| < 6 ng/L · calculated | < detection limit | Le Barp | LE BARP | |
| < 6 ng/L · calculated | 0 ng/L | Le Barp | LE BARP | |

Frequently asked questions
Is tap water in Belin-Béliet safe to drink?
Yes. At the check on 30 June 2026, the tap water in Belin-Béliet was within every limit tested. “Eau conforme aux limites réglementaires de qualité des eaux destinées à la consommation humaine pour les paramètres mesurés mais ne satisfaisant pas aux références de qualité pour le paramètre de la température de l'eau.”
How high are PFAS levels in Belin-Béliet'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 Belin-Béliet 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 6 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.
Are PFAS levels rising in Belin-Béliet'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 Belin-Béliet?
The water hardness in Belin-Béliet is 13.5 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
