PFAS in drinking water

No PFAS detected

Amount found in the water < 6 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, none found
Our health benchmark 0.5 ng/L

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 Paulhiac, on the same distribution network as Laussou (NORD DU LOT - PAULHIAC). 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 1.5 ng/L upward. None reached that limit, so their total is below 6 ng/L rather than zero.

None found. The lab sees nothing below 6 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Laussou, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 9 September 2025. 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: <0,044 µg/L, below the EU legal limit (100 ng/L). Sampled in Paulhiac, on the same network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Values to watch

These results are close to their legal limit, or over it.

Outside a reference value: Turbidity 5.1 NFU on 12 February 2026 (reference ≤ 2 NFU). These are indicator parameters with reference values, not legal limits.

Frequently asked questions

Is tap water in Laussou safe to drink?

Yes. At the check on 12 February 2026, the tap water in Laussou was within every limit tested. Outside a reference value: Turbidity 5.1 NFU on 12 February 2026 (reference ≤ 2 NFU). 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 Laussou's drinking water?

At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 44 ng/L. The EU limit is 100 ng/L, so this water is under 44 % of the limit. (below the EU limit)

Does the water in Laussou 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.

How hard is the water in Laussou?

The water hardness in Laussou is 27.3 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?

All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 12 September 2026.

Same water network

Same distribution network as Laussou, so in principle the same water.
