PFAS in Bains's tap water: under 8 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 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 Bains, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 6 July 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). 2 checks since 16 December 2025, PFAS-4 always below the detection limit (2 ng/L).

What the latest check found
At the latest check, the water was within every limit tested.
Values to watch
These results are close to their legal limit, or over it.
Outside a reference value: Turbidity 3 NFU on 6 July 2026 (reference ≤ 2 NFU). These are indicator parameters with reference values, not legal limits.
| What was tested | Value | Limit | Status |
|---|---|---|---|
| Nitrate | 37 mg/L | ≤ 50 mg/L | within the limit |

Frequently asked questions
Is tap water in Bains safe to drink?
Yes. At the check on 6 July 2026, the tap water in Bains was within every limit tested. Outside a reference value: Turbidity 3 NFU on 6 July 2026 (reference ≤ 2 NFU). 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 Bains'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 Bains 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 Bains's tap water?
Too few quantified checks to say (0 since 16 December 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Bains?
The water hardness in Bains is 10.4 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
