AS Mixed-use Rural 3-monthly Pre-treatment Water Quality Monitoring

For drinking water supplies using the Acceptable Solution for Mixed-Use Rural Water Supplies (AS-MR), this suite provides regular 3-monthly monitoring of raw water quality before treatment, ensuring that microbial and chemical parameters remain within acceptable limits.

Why This Suite Is Important

Frequent monitoring of microbiological contaminants, nitrate levels, pH, and turbidity is essential for ensuring that pre-treatment systems are functioning correctly. High levels of E. coli or turbidity can indicate treatment inefficiencies or contamination risks, while nitrate levels and pH changes could suggest issues with source water or treatment effectiveness. Regular testing helps identify early warning signs of system failure and ensures compliance with drinking water regulations.

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

  • E. coli: Must not be detected in 100 mL samples
  • Nitrate: 50 mg/L as NO₃
  • pH: 7.0 – 8.5 (recommended for drinking water)
  • Turbidity: <1.0 NTU for effective disinfection
  • 📌 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.
  • 💬 Need Help?
  • Once you receive your results, we can introduce you to a water quality expert with knowledge of drinking water and treatment options to assist in understanding the results and developing a drinking water supply strategy.
