Our health benchmark 0.5 ng/L

The lab sees nothing below 3 ng/L, 6 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 0.5 to 1.5 ng/L upward. None reached that limit, so their total is below 3 ng/L rather than zero.

In Ploemeur, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 9 July 2026. The total is below 3 ng/L, the sum of the detection limits and 6 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). 8 checks since 24 February 2025: PFAS-4 up to 13 ng/L, sometimes below the detection limit, averaging at least 3.65 ng/L over 12 months (non-detects as 0). No clear trend. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

PFAS over time in Ploemeur

8 PFAS checks since 24 February 2025, values as published. Samples from 2 communes on the same network: it's the same water, so each one applies to Ploemeur. Samples come from 2 distribution networks. The trend refers to the network “PLOEMEUR EST”.

Frequently asked questions

Is tap water in Ploemeur safe to drink?

Yes. At the check on 9 July 2026, the tap water in Ploemeur was within every limit tested. “Eau d'alimentation conforme aux limites de qualité et satisfaisant aux références de qualité pour les paramètres analysés à l'exception d'une température ne satisfaisant pas à la référence de qualité fixée à 25°C, en lien avec les fortes chaleurs observées et à l’exception d'une teneur en chlorates supérieure à 250 µg/L. Pour ce paramètre, la valeur la plus faible possible doit être visée sans pour autant compromettre la désinfection. Une concentration en chlorates supérieure à 250 µg/L et inférieure à 700 µg/L peut être tolérée de manière temporaire, uniquement lorsque la présence de chlorates s'explique par le procédé de désinfection mis en œuvre. Un suivi renforcé sera mis en place sur ce paramètre.”

How high are PFAS levels in Ploemeur'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 Ploemeur 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 3 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 Ploemeur's tap water?

No clear trend. Since 24 February 2025, 8 checks have been published; on the main network the PFAS-4 sum ranged between 0.9 ng/L and 13 ng/L (3 quantified values), at times below the detection limit. pfasnearme only reports a trend from a change of at least 25 % and 1 ng/L.

How hard is the water in Ploemeur?

The water hardness in Ploemeur is 21.1 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
