What's in your water
Key parameters explained in plain English
Water Hardness
At 129 mg/L, Evanston's water is classified as hard. You may notice some limescale buildup in kettles and appliances. The ADWG aesthetic guideline is 200 mg/L.
pH Level
pH of 0.05 is outside the recommended range of 6.5–8.5. Water outside this range may taste metallic or cause pipe corrosion.
Fluoride
Fluoride measured at 0.6 mg/L. Within the recommended 0.6–1.1 mg/L range for dental health.
Chlorine (Disinfection)
Chlorine at 0.4 mg/L (ADWG limit: 5 mg/L). Used to kill harmful bacteria and ensure water stays safe in the pipes. May affect taste — a carbon filter or refrigerating water can reduce chlorine.
E. coli
No E. coli detected — the water meets the ADWG standard of zero E. coli per 100 mL. This indicates effective disinfection.

Utility reports average the grid — not your home
Evanston'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.
