PFAS in drinking water

No PFAS detected

Amount found in the water < 10 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 10 ng/L, 20 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 Ancenis-Saint-Géréon, on the same distribution network as Ingrandes-le-Fresne-sur-Loire (INGRANDES_LE FRESNE). 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 4 ng/L upward. None reached that limit, so their total is below 10 ng/L rather than zero.

In Ingrandes-le-Fresne-sur-Loire, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 23 July 2025. The total is below 10 ng/L, the sum of the detection limits and 20 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). Sampled in Ancenis-Saint-Géréon, on the same network. 2 checks since 23 January 2025, sum of 20 PFAS always below the detection limit.

Frequently asked questions

Is tap water in Ingrandes-le-Fresne-sur-Loire safe to drink?

All the values shown here (29 July 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité.”

How high are PFAS levels in Ingrandes-le-Fresne-sur-Loire'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 Ingrandes-le-Fresne-sur-Loire 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 10 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 Ingrandes-le-Fresne-sur-Loire'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 Ingrandes-le-Fresne-sur-Loire?

The water hardness in Ingrandes-le-Fresne-sur-Loire is 18.7 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
