PFAS in Bourg-Saint-Andéol's tap water: 1 ng/L, 2x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
2× above our health benchmark
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 Saint-Marcel-d'Ardèche, on the same distribution network as Bourg-Saint-Andéol (CCDRAGA BSABIDON). 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.
Substances below the detection limit count as 0, so the real total may be higher.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Bourg-Saint-Andéol, the 4 most closely watched PFAS (PFAS-4) add up to 1 ng/L (0.001 µg/L) at the latest PFAS check on 8 July 2026. That's 2 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 16 ng/L (0.016 µg/L), below the EU legal limit (100 ng/L). Sampled in Saint-Marcel-d'Ardèche, on the same network. 5 checks since 29 September 2025: PFAS-4 up to 1 ng/L, sometimes below the detection limit.

PFAS over time in Bourg-Saint-Andéol
24 PFAS checks since 19 January 2023, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Bourg-Saint-Andéol. Samples come from 4 distribution networks. The trend refers to the network “CCDRAGA PRINCIPAL”.
“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 Bourg-Saint-Andéol safe to drink?
Yes. At the check on 8 July 2026, the tap water in Bourg-Saint-Andéol was within every limit tested. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité.”
How high are PFAS levels in Bourg-Saint-Andéol's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 16 ng/L. The EU limit is 100 ng/L, so this water is at 16 % of the limit. (below the EU limit)
Does the water in Bourg-Saint-Andéol also meet the strictest limits in Europe?
Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 1 ng/L stays below.
Are PFAS levels rising in Bourg-Saint-Andéol's tap water?
Too few quantified checks to say (2 since 19 January 2023). 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 Bourg-Saint-Andéol?
The water hardness in Bourg-Saint-Andéol is 33.4 °f (hard). 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.
