Explained
What these numbers mean
Soft (53 mg/L)
Water Hardness
Your water is classified as soft, which means minimal limescale buildup on fixtures and appliances. Soap and shampoo will lather easily, and you should notice no drying effects on skin or hair. Hot water systems and kettles are unlikely to suffer scale-related efficiency losses.
Outside Range
pH Level
pH of 21.2 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 0.81 mg/L. Within the recommended 0.6–1.1 mg/L range for dental health.
Chlorine
Disinfection
Chlorine measured at 0.4 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
Armstrong Creek'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.
