Drinking water quality in Lewarde

Region: Hauts-de-France Population: 2,353 Water supplier: SIDEN-SIAN NOREADE PECQUENCOURT Latest sample: 19 May 2026
Passes the EU legal limit and below the health limit

PFAS in drinking water

EU legal limit
<0,001 µg/L Limit: 0.1 µg/L within limit

The total of 20 PFAS ("forever chemicals") was last measured at <0,001 µg/L. The EU limit is 0.1 µg/L, so this water is at 0 % of the limit. (12 February 2026)

Health limit (used in Sweden)
0 µg/L the 4 most harmful PFAS (PFAS-4) · Limit: 0.004 µg/L below health limit

The four most harmful PFAS add up to 0 µg/L, below the health limit of 0.004 µg/L used in Sweden since 2026.

Substances too small to measure count as 0, so the real total may be higher.

Frequently asked questions

Is tap water in Lewarde safe to drink?

Yes. The latest official test (19 May 2026) checked the tap water in Lewarde and it passed every requirement.

How high are PFAS levels in Lewarde's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at <0,001 µg/L. The EU limit is 0.1 µg/L, so this water is at 0 % of the limit. (below the EU limit)

Does the water in Lewarde also meet the strictest limits in Europe?

Yes. Even against Europe's strictest limit, the health limit of 0.004 µg/L used in Sweden since 2026, the measured value of 0 µg/L stays below.

How hard is the water in Lewarde?

The water hardness in Lewarde is 39.83 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
