PFAS in Sammeron's tap water: 4 ng/L, 8x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
8× above our health benchmark
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 Chamigny, on the same distribution network as Sammeron (FERTE-SOUS-JOUARRE - CDA CPB). 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.
Substances below the detection limit count as 0, so the real total may be higher.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Sammeron, the 4 most closely watched PFAS (PFAS-4) add up to 4 ng/L (0.004 µg/L) at the latest PFAS check on 25 June 2026. That's 8 times our 0.5 ng/L health benchmark, exactly at Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 7 ng/L (0.007 µg/L), below the EU legal limit (100 ng/L). Sampled in Chamigny, on the same network. 4 checks since 11 February 2026: PFAS-4 up to 4 ng/L, sometimes below the detection limit.

Details and sources
PFAS over time in Sammeron
8 PFAS checks since 23 May 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Sammeron. Samples come from 5 distribution networks. The trend refers to the network “FERTE-SOUS-JOUARRE - CDA CPB”.
“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 Sammeron safe to drink?
At the latest check, the water was over at least one limit. “Eau d’alimentation non-conforme aux limites de qualité pour les paramètres chlorothalonil R417888, chloridazone desphényl, chloridazone méthyl desphényl et la somme totale des pesticides sans dépassement des seuils sanitaires. Eau d’alimentation présentant un dépassement de la valeur indicative pour le paramètre chlorothalonil R471811 (métabolite non pertinent). En l’état actuel des connaissances scientifiques, aucune restriction d’usage n’est nécessaire. Un suivi renforcé est mis en place pour surveiller l’évolution de la situation. La personne responsable de la distribution de l’eau doit engager un programme d’actions visant à réduire les teneurs des paramètres concernés. Les autres paramètres recherchés dans le cadre du contrôle sanitaire sont conformes aux exigences du code de la santé publique.”
How high are PFAS levels in Sammeron's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 7 ng/L. The EU limit is 100 ng/L, so this water is at 7 % of the limit. (below the EU limit)
Does the water in Sammeron also meet the strictest limits in Europe?
Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 4 ng/L stays below.
Are PFAS levels rising in Sammeron's tap water?
Too few quantified checks to say (2 since 23 May 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.
How hard is the water in Sammeron?
The water hardness in Sammeron is 31 °f (hard). 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.
Same water network
Same distribution network as Sammeron, so in principle the same water.
