PFAS in drinking water

No PFAS detected

Amount found in the water < 6 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, none found
Our health benchmark 0.5 ng/L

The lab sees nothing below 6 ng/L, 12 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 Boé, on the same distribution network as Agen (AGGLOMERATION AGEN -LACAPELETTE). 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 ng/L upward. None reached that limit, so their total is below 6 ng/L rather than zero.

None found. The lab sees nothing below 6 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Agen, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 13 April 2026. The total is below 6 ng/L, the sum of the detection limits and 12 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). Sampled in Boé, on the same network. 4 checks since 14 August 2025, sum of 20 PFAS always below the detection limit (44 ng/L).

PFAS over time in Agen

4 PFAS checks since 14 August 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Agen. Samples come from 2 distribution networks. The trend refers to the network “AGGLOMERATION AGEN -LACAPELETTE”.

“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 Agen safe to drink?

All the values shown here (24 July 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”

How high are PFAS levels in Agen'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 Agen 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 6 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 Agen'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 Agen?

The water hardness in Agen is 12.3 °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.
