PFAS in drinking water

None of the 4 most harmful PFAS detected

Amount found in the water < 4 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, 12 ng/L found in total
Our health benchmark 0.5 ng/L

The lab sees nothing below 4 ng/L, 8 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.

How we chose 0.5 ng/L

Sample taken in Grigny-sur-Rhône, on the same distribution network as Loire-sur-Rhône (LOIRE SUR RHONE). The health authority samples one tap per network; a network carries the same treated water everywhere.

The US also limits PFOA and PFOS to 4 ng/L each, per substance.

The lab detects each of the four substances from 1 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

In Loire-sur-Rhône, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 4 June 2026. The total is below 4 ng/L, the sum of the detection limits and 8 times our 0.5 ng/L benchmark. Sum of 20 PFAS: 12 ng/L (0.012 µg/L), below the EU legal limit (100 ng/L). Sampled in Grigny-sur-Rhône, on the same network. 11 checks since 11 September 2025: PFAS-4 up to 36 ng/L, sometimes below the detection limit, averaging 19.6 ng/L over 12 months. Rising on the main network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

PFAS over time in Loire-sur-Rhône

52 PFAS checks since 3 February 2023, from the published measurements. Samples from 18 communes on the same network: it's the same water, so each one applies to Loire-sur-Rhône. Samples come from 2 distribution networks. The trend refers to the network “MONTS DU LYONNAIS”.

“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 Loire-sur-Rhône safe to drink?

Yes. At the check on 7 July 2026, the tap water in Loire-sur-Rhône was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”

How high are PFAS levels in Loire-sur-Rhône's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 12 ng/L. The EU limit is 100 ng/L, so this water is at 12 % of the limit. (below the EU limit)

Does the water in Loire-sur-Rhône also meet the strictest limits in Europe?

As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 4 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.

Are PFAS levels rising in Loire-sur-Rhône's tap water?

Yes. On the main network, the PFAS-4 sum rose from 15 ng/L (11 September 2025) to 22 ng/L (22 May 2026) across 5 quantified checks. pfasnearme's benchmark is 0.5 ng/L as an annual mean. These history statistics use laboratory-published sums only.

How hard is the water in Loire-sur-Rhône?

The water hardness in Loire-sur-Rhône is 24.8 °f (medium). 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.
