PFAS in Saint-Jean-de-Verges'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 Loubières, on the same distribution network as Saint-Jean-de-Verges (CRAMPAGNA LOUBIERES SAINT JEAN). 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.

In Saint-Jean-de-Verges, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 3 March 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 Loubières, on the same network. 2 checks since 10 February 2026, PFAS-4 always below the detection limit (2 ng/L).

PFAS over time in Saint-Jean-de-Verges
5 PFAS checks since 25 August 2025, from the published measurements. Samples from 4 communes on the same network: it's the same water, so each one applies to Saint-Jean-de-Verges. Samples come from 3 distribution networks. The trend refers to the network “BASSE VALLEE DE L'ARIEGE”.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions
Is tap water in Saint-Jean-de-Verges safe to drink?
At the latest check, the water was over at least one limit. “Présence de chlorure de vinyle monomère (CVM) à une concentration supérieure à la limite de qualité réglementaire ( 0,5 µg/l). L'interdiction de consommation prononcée sur ce réseau suite à la présence récurrente de cet élément est maintenue. Des actions doivent être réalisées pour permettre de distribuer une eau conforme à la réglementation.”
How high are PFAS levels in Saint-Jean-de-Verges'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 Saint-Jean-de-Verges 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 Saint-Jean-de-Verges's tap water?
Too few quantified checks to say (0 since 25 August 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.
How hard is the water in Saint-Jean-de-Verges?
The water hardness in Saint-Jean-de-Verges is 17.9 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
