PFAS in drinking water

No PFAS detected

Amount found in the water < 8 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 8 ng/L, 16 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.

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 ng/L upward. None reached that limit, so their total is below 8 ng/L rather than zero.

None found. The lab sees nothing below 8 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Bonneval, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 7 April 2026. The total is below 8 ng/L, the sum of the detection limits and 16 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,005 µg/L, below the EU legal limit (100 ng/L). 3 checks since 17 February 2026, PFAS-4 always below the detection limit (2 ng/L).

Frequently asked questions

Is tap water in Bonneval safe to drink?

Yes. At the check on 22 June 2026, the tap water in Bonneval was within every limit tested. Outside a reference value: pH 5.9 unité pH on 22 June 2026 (reference 6.5–9 unité pH), Electrical conductivity 74 µS/cm on 22 June 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité.”

How high are PFAS levels in Bonneval's drinking water?

At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 5 ng/L. The EU limit is 100 ng/L, so this water is under 5 % of the limit. (below the EU limit)

Does the water in Bonneval 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 8 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 Bonneval's tap water?

Too few quantified checks to say (0 since 17 February 2026). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.

How hard is the water in Bonneval?

The water hardness in Bonneval is 1.6 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?
