What these numbers mean
Moderately hard (85.2 mg/L)
Water Hardness
Your water is moderately hard. You may notice light limescale deposits on kettle elements and taps over time. Soap lathers reasonably well, though slightly more product may be needed. Skin and hair are generally unaffected, and appliance lifespan should not be significantly reduced at this level.
Outside Range
pH Level
pH of 27.9 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 0.83 mg/L. Within the recommended 0.6–1.1 mg/L range for dental health.
Chlorine
Disinfection
Chlorine measured at 1.1 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
Gumdale'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.
