Explained
What these numbers mean
Very hard (575 mg/L)
Water Hardness
Your water is very hard, meaning significant limescale buildup is likely on appliances, fixtures, and heating elements. Soap will struggle to lather, and you may notice dry skin or dull hair after washing. Regular descaling of kettles, dishwashers, and hot water systems is strongly recommended.
Outside Range
pH Level
pH of 0.05 is outside the ideal range of 6.5–8.5. The ADWG recommends pH between 6.5 and 8.5 for drinking water.
Fluoridated
Fluoride
Fluoride at 1 mg/L. Within the recommended 0.6–1.1 mg/L range for dental health.
Chlorine
Disinfection
Chlorine measured at 1.3 mg/L, well within the ADWG guideline of 5 mg/L. Used for disinfection to keep water safe. May affect taste slightly — refrigerating water or using a carbon filter can help.

Utility reports average the grid — not your home
Netherton's water meets ADWG standards at the source, but old pipes, roof tanks, and ageing plumbing can add lead, copper or bacteria before the water reaches your tap. These won't show up in your utility report.
Check your own tap before buying a filter or assuming the suburb average matches your home.
