TS22 tap water: what's in it?

Northumbrian, Essex and Suffolk Water group (figures include Northumbrian Water): at least 36 tests failed UK drinking-water standards in 2025 (DWI, company-wide).

Some published DWI figures don't reconcile or identify a company, so we've left them out; the true number may be higher. England overall: 99.97% of tests met standards.
