PFAS in Ladinhac's tap water: under 13 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 13 ng/L, 26 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 Lapeyrugue, on the same distribution network as Ladinhac (LADINHAC PAR LAPEYRUGUE). 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 to 5 ng/L upward. None reached that limit, so their total is below 13 ng/L rather than zero.

In Ladinhac, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 6 July 2026. The total is below 13 ng/L, the sum of the detection limits and 26 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,0895 µg/L, below the EU legal limit (100 ng/L). Sampled in Lapeyrugue, on the same network. 9 checks since 2 September 2025: PFAS-4 up to 50 ng/L, sometimes below the detection limit, averaging at least 12.5 ng/L over 12 months (non-detects as 0).

What the latest check found
At the latest check, the water was within every limit tested.
Values to watch
These results are close to their legal limit, or over it.
Outside a reference value: pH 6.4 unité pH on 20 May 2026 (reference 6.5–9 unité pH), Electrical conductivity 80 µS/cm on 20 May 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits.

Frequently asked questions
Is tap water in Ladinhac safe to drink?
At the latest check, the water was over at least one limit. “Eau de qualité sanitaire satisfaisante. Surveiller le taux de nitrates.”
How high are PFAS levels in Ladinhac's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 89.5 ng/L. The EU limit is 100 ng/L, so this water is under 89 % of the limit. (below the EU limit)
Does the water in Ladinhac 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 13 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 Ladinhac's tap water?
Too few quantified checks to say (1 since 2 September 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Ladinhac?
The water hardness in Ladinhac is 1.6 °f (soft). 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 21 September 2026.
