PFAS in drinking water

No 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, none found
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.

Sample taken in Vavray-le-Grand, on the same distribution network as Saint-Lumier-en-Champagne (SMVU DE SAINT AMAND EST). 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 1 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

In Saint-Lumier-en-Champagne, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 16 January 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: <0,029 µg/L, below the EU legal limit (100 ng/L). Sampled in Vavray-le-Grand, on the same network. 2 checks since 2 April 2025, sum of 20 PFAS always below the detection limit (29 ng/L).

PFAS over time in Saint-Lumier-en-Champagne

2 PFAS checks since 2 April 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Saint-Lumier-en-Champagne.

“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 Saint-Lumier-en-Champagne safe to drink?

At the latest check, the water was over at least one limit. “Eau NON CONFORME pour les paramètres physico-chimiques contrôlés. Teneur en NITRATES supérieure à la limite de qualité fixée à 50 mg/l. L'eau peut être utilisée pour les usages sanitaires courants mais ne doit pas être consommée par les nourrissons et les femmes enceintes. Par ailleurs, on note une valeur de CHLORE LIBRE élevée. La concentration en chlore devra être maintenue inférieure à 0,5 mg/l sur le réseau de distribution.”

How high are PFAS levels in Saint-Lumier-en-Champagne's drinking water?

At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 29 ng/L. The EU limit is 100 ng/L, so this water is under 29 % of the limit. (below the EU limit)

Does the water in Saint-Lumier-en-Champagne 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 Saint-Lumier-en-Champagne'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 Saint-Lumier-en-Champagne?

No hardness value is available for Saint-Lumier-en-Champagne in this source.
