PFAS in Juillan's tap water: under 17 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 17 ng/L, 34 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 Azereix, on the same distribution network as Juillan (MARQUISAT JUILLAN). 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 5 ng/L upward. None reached that limit, so their total is below 17 ng/L rather than zero.

None found. The lab sees nothing below 17 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Juillan, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 9 June 2026. The total is below 17 ng/L, the sum of the detection limits and 34 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,1 µg/L, below the EU legal limit (100 ng/L). Sampled in Azereix, on the same network. 2 checks since 14 April 2026, PFAS-4 always below the detection limit (17 ng/L).

PFAS over time in Juillan
2 PFAS checks since 14 April 2026, values as published. Samples from 2 communes on the same network: it's the same water, so each one applies to Juillan.
| Date | PFAS-4 | Sum of 20 PFAS | Sampled at |
|---|---|---|---|
| < 17 ng/L | < 100 ng/L | Azereix | |
| < 17 ng/L | < 100 ng/L | Arcizac-ez-Angles |
“<” means not detected, the figure being the detection limit. “–” means not published. Labs have only reported the PFAS-4 sum (SANDRE code 9268) since autumn 2025. How to read a PFAS result

Frequently asked questions
Is tap water in Juillan safe to drink?
Yes. At the check on 21 July 2026, the tap water in Juillan was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in Juillan's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 100 ng/L. The EU limit is 100 ng/L, so this water is under 100 % of the limit. (below the EU limit)
Does the water in Juillan 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 17 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 Juillan's tap water?
Too few quantified checks to say (0 since 14 April 2026). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Juillan?
The water hardness in Juillan is 9.3 °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.
