PFAS in Saillagouse's tap water: under 24 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 24 ng/L, 48 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 Err, on the same distribution network as Saillagouse (ERR - SAILLAGOUSE ZA - VÉDRIGNANS). 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 10 ng/L upward. None reached that limit, so their total is below 24 ng/L rather than zero.

None found. The lab sees nothing below 24 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Saillagouse, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 30 June 2026. The total is below 24 ng/L, the sum of the detection limits and 48 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,002 µg/L, below the EU legal limit (100 ng/L). Sampled in Err, on the same network. 3 checks since 25 March 2026, PFAS-4 always below the detection limit (2 ng/L). Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).
Details and sources
PFAS over time in Saillagouse
4 PFAS checks since 22 October 2025, from the published measurements. Samples from 4 communes on the same network: it's the same water, so each one applies to Saillagouse. Samples come from 3 distribution networks. The trend refers to the network “SAILLAGOUSE BAS SERVICE”.
“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 |
|---|---|---|---|---|
| < 2 ng/L | < 2 ng/L | Err | ERR - SAILLAGOUSE ZA - VÉDRIGNANS, SAILLAGOUSE BAS SERVICE | |
| < 2 ng/L | < 2 ng/L | Saillagouse | SAILLAGOUSE BAS SERVICE | |

| < 24 ng/L · calculated | < 2 ng/L | Eyne | EYNE- SAILLAGOUSE HT- ESTAVAR |
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 Saillagouse safe to drink?
Yes. At the check on 30 June 2026, the tap water in Saillagouse was within every limit tested. Outside a reference value: Electrical conductivity 138 µS/cm on 30 June 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité.”
How high are PFAS levels in Saillagouse's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 2 ng/L. The EU limit is 100 ng/L, so this water is under 2 % of the limit. (below the EU limit)
Does the water in Saillagouse 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 24 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 Saillagouse's tap water?
No. Since 22 October 2025, 3 checks have been published and the PFAS-4 sum stayed below the laboratory's detection limit (2 ng/L) every time. These history statistics use laboratory-published sums only.
How hard is the water in Saillagouse?
The water hardness in Saillagouse is 6.4 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
