The published numbers

What's in Adelaide's tap water?

Adelaide's AVERAGE tap water — not the peaks, the average — would be illegal to supply in the European Union.

Adelaide's average trihalomethane level runs ~103–123 µg/L against the EU's legally binding limit of 100. That makes Adelaide the only Australian capital whose everyday water — not a bad day, the average — exceeds what European law permits. It's fully legal here, because Australia's 250 µg/L figure is a guideline nobody has to obey. Add moderate hardness and dosed fluoride, and Adelaide is the strongest case for home filtration in the country.

Trihalomethanes (THMs) ~103–123 µg/L average · EU legal limit is 100

Fluoride Added · ~0.5–0.8 mg/L

Water hardness ~99–137 mg/L · scaling kettles and hot-water systems now

Chlorine ~0.3–0.5 mg/L residual — in every shower and glass

Sodium ~55 mg/L average · River Murray influence

Dissolved solids (TDS) ~311 mg/L average — you can taste this

E. coli 100% health compliance — zero detections

Every figure comes from SA Water's published reporting — Water Quality Performance Results, data.sa.gov.au. Measured where the water leaves the plant — the mains to your door are never tested.
