Lowest to highest results, 12 months to August 2026, Gold Coast zone (Seqwater monthly water quality report, PDF). Your tap can differ.
Where Gold Coast water comes from
Mostly Hinze and Little Nerang dams, treated at the Molendinar and Mudgeeraba water treatment plants. Parts of the city can also get water from Wivenhoe and Somerset dams through the Southern Regional Pipeline (Seqwater, PDF). The Gold Coast Desalination Plant at Tugun can produce up to 133 million litres a day for the Gold Coast, Logan and Brisbane (Seqwater, PDF).
Disinfectant
Chlorine. Seqwater's Gold Coast results average about 1.7 mg/L free chlorine over 12 months, within the 5 mg/L health guideline (Seqwater, PDF). Many people taste or smell chlorine above about 0.6 mg/L, and a hot shower releases it into the steam.
Rain, sediment and taste
Seqwater says earthy, musty tastes from MIB and geosmin are more likely after hot and rainy weather, and are safe to drink (Seqwater). Its 12-month Gold Coast results show turbidity averaging 0.2 NTU, with one of 284 samples at 5.2 NTU, just over the 5 NTU aesthetic guideline. That's the kind of event a sediment stage is for.
Hardness
Soft. The 12-month average is about 40 mg/L as calcium carbonate, against an aesthetic guideline of 200 mg/L. Most Gold Coast homes don't need a scale conditioner.

Why does Gold Coast water sometimes taste earthy?
Seqwater says earthy or musty tastes come from naturally occurring MIB and geosmin in the raw water, are more likely after hot and rainy weather, and are safe to drink. Carbon filtration reduces them.
Is there PFAS in Gold Coast water?
Seqwater tests the bulk supply against the Australian Drinking Water Guidelines and publishes its results. The only way to know your own tap is a NATA-accredited lab test; ask your Water Specialist at your free water test.

Whole Home, or Whole Home + Mineral for a better-tasting kitchen tap. Carbon handles the chlorine; scale control usually isn't needed. Hinterland homes on rainwater add UV.
