General Roof Water Chemistry (Annual Monitoring – No Chimney or Open Fire)

For roof water supplies collected from properties without chimneys or open fires, ensuring annual monitoring to assess the impact of roofing materials on water quality and safety.

Why This Suite Is Important

Roof-collected rainwater can accumulate heavy metals from roofing materials, gutters, and atmospheric deposition, affecting the quality of your drinking water.

  • Lead and cadmium may leach from roofing components, especially older structures.
  • Copper and zinc can dissolve from roof flashings, coatings, or tank linings.
  • Regular monitoring helps ensure that your water remains suitable for drinking and household use.

 

The Maximum Acceptable Values (MAVs) and treatment limits for these determinands are:

Chemical & Physical Contaminants:

  • Cadmium: 0.004 mg/L
  • Copper: 2.0 mg/L
  • Lead: 0.01 mg/L
  • Zinc: 1.5 mg/L (Aesthetic guideline only)
  • 📌 If you have a Safe Supply Online Drinking Water Safety Plan, your test results can be automatically shared with the online tool, made available to members of your water supply, and scheduled for submission to the regulator as required.
  • 📌 Results must be retained for at least 5 years and made available to all members of the water supply.
