Other figures worth knowing
Chlorine by-products (THMs)0.058mg/L
pH8
Dissolved solids405mg/L
Sodium100mg/L
Perth's water is disinfected with free chlorine at roughly 0.4–1.0 mg/L network-wide. The figure above is trihalomethanes (THMs) — by-products of chlorination that a catalytic carbon filter reduces. In Hamilton Hill they run at about 23% of the safety guideline.
