The published numbers

What's in Sydney's tap water?

Sydney's water is chloraminated mains-wide — and every limit on it is a guideline, not a law.

Sydney's supply is chloraminated mains-wide and fluoridated to a 1.0 mg/L target (NSW Health permits up to 1.5). None of this breaks any law here — because Australia's drinking water limits aren't laws. They're recommendations. And Sydney Water publishes no city-wide lead figures: past your meter, nobody is testing what your own pipes add.

Chlorine & chloramine Both dosed mains-wide — in every shower and glass
Fluoride Added · ~1.01 mg/L average — dosed to a 1.0 target
Heavy metals ~0.0001–0.0004 mg/L at the plant · the mains to your door are untested
PFAS ("forever chemicals") Trace levels detected — within guidelines at all 9 plants
Sodium ~13–18 mg/L typical
Water hardness ~57 mg/L · soft
E. coli 100% clean — 0 of 1,260 samples this year

Every figure comes from Sydney Water's published reporting — Quarterly Drinking Water Quality Report, year to 30 June 2025. Measured where the water leaves the plant — the mains to your door are never tested.
