PFAS in Boussac-Bourg'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 Saint-Silvain-Bas-le-Roc, on the same distribution network as Boussac-Bourg (BUSSIERE ST GEORGES - LAVAUFRANCHE). 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 Boussac-Bourg, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 22 June 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: <SEUIL µg/L, below the EU legal limit (100 ng/L). Sampled in Saint-Silvain-Bas-le-Roc, on the same network. 6 checks since 22 September 2025, sum of 20 PFAS always below the detection limit.

PFAS over time in Boussac-Bourg
6 PFAS checks since 22 September 2025, from the published measurements. Samples from 4 communes on the same network: it's the same water, so each one applies to Boussac-Bourg. Samples come from 3 distribution networks. The trend refers to the network “BOUSSAC SOUMANS LEYRAT”.
“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 Boussac-Bourg safe to drink?
Yes. At the check on 22 June 2026, the tap water in Boussac-Bourg was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité définies par le Code de la Santé Publique, pour les paramètres mesurés au moment du prélèvement, à l’exception de l'équilibre calco-carbonique. Eau agressive qui nécessite une optimisation du traitement de reminéralisation. A noter la présence de métabolites non pertinents de pesticides, le chlorothalonil R471811, l'ESA métolachlore et l'ESA métazachlore, à des teneurs cependant inférieures à la valeur indicative fixée à 0,9 µg/L. Un programme renforcé de suivi de la qualité de l'eau est en cours.”
How high are PFAS levels in Boussac-Bourg's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at –. The EU limit is 100 ng/L, so this water is at – of the limit. (below the EU limit)
Does the water in Boussac-Bourg 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 Boussac-Bourg's tap water?
Calculated PFAS-4 values are listed in the table. The chart uses laboratory-published sum-of-20 results; there are too few laboratory-published PFAS-4 sums for the existing trend calculation.
How hard is the water in Boussac-Bourg?
The water hardness in Boussac-Bourg is 9.8 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
