  During the year a sample failed the legal limit, but only in isolation (a single sample, or under 5% of samples). The rating reflects the water supplied to the zone rather than one sample; every failure is counted in the compliance line at the top of this report and shown in the full parameter list.

  PFAS are regulated by the Swedish Food Agency (LIVSFS 2022:12). From 2026 the limit is 4 ng/l for the sum of four PFAS (PFAS 4) and 100 ng/l for 21 PFAS (PFAS 21). The card rates PFAS 4 where it is reported, otherwise PFAS 21. Where no value appears, the water utility has not reported one.

The "Filtered" column shows the estimated result after filtering with TAPP Water EcoPro filters.

During the report period, a small number of water samples did not meet drinking water standards. This may be due to old pipes or local plumbing in the neighbourhood. View all parameters
