What this means for your tap water

Important context: the Environment Agency data shown here is from environmental monitoring of rivers and groundwater — not treated tap water. PFAS detected in source water does not necessarily mean the same levels are present in the water that comes out of your tap.

Water treatment processes can reduce PFAS concentrations, though the effectiveness varies by treatment method and PFAS compound. UK water companies are not required to publish PFAS removal rates. If you are concerned, a reverse osmosis filter offers the most reliable protection at home.

How to reduce PFAS exposure

A reverse osmosis system is the most effective way to remove PFAS from your drinking water at home, eliminating over 95% of forever chemicals.

Frequently asked questions

Has PFAS been found in Norwich water?

Yes. Environment Agency monitoring has detected 18 PFAS compounds across 11 sampling points in water sources near Norwich. The highest recorded level is 0.025 µg/L (PFOS). Note that this is environmental monitoring of rivers and groundwater, not treated tap water.

What PFAS compounds were found in Norwich?

The following PFAS compounds have been detected near Norwich: PFOA, PFOS, PFHxS (linear), PFOS (branched), PFHxS (branched), PFPeA, PFHxA, PFOS (linear), PFHpA, PFBA, PFBS, FBSA, PFHxSA, PFPeS, PFHpS, 5:3 FTCA, 6:2 FtSAB, PFOS (total). PFOS was recorded at the highest level of 0.025 µg/L.

Is Norwich tap water safe to drink despite PFAS?

Norwich tap water meets all current UK legal standards. However, the UK has no legal limit for PFAS in drinking water. The Environment Agency data shows PFAS in source water (rivers and groundwater), not in treated tap water. Water treatment may reduce PFAS levels, but the extent of removal is not publicly reported.

How can I remove PFAS from my water in Norwich?

The most effective method is a reverse osmosis (RO) filtration system, which removes over 95% of PFAS compounds. Standard carbon filters and jug filters like BRITA do not effectively remove PFAS. An under-sink RO system is recommended for Norwich households concerned about PFAS exposure.
