Well Driller Groundwater Quality Analysis

A highly recommended suite for groundwater quality assessment, specifically designed for well drilling and water supply development.

Why is this suite important?

When drilling a new well or assessing an existing bore, understanding the chemical composition of the groundwater is essential. Metals, nutrients, and other dissolved components can affect the safety, taste, and suitability of the water for drinking and treatment system design.

This analysis ensures that the water meets drinking water guidelines and highlights any potential issues such as heavy metal contamination, excessive hardness, or chemical imbalances that may require treatment.

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

  • Arsenic: 0.01 mg/L
  • Ammonia: 1.5 mg/L
  • Bromine: Not specified under MAV, but monitored due to potential disinfection by-products
  • Calcium & Hardness: No MAV, but hardness >200 mg/L can cause scaling issues
  • Chloride: 250 mg/L (Aesthetic value due to taste issues)
  • Iron: 0.2 mg/L (Aesthetic guideline, staining at high levels)
  • Magnesium: No MAV, but high levels contribute to hardness
  • Manganese: 0.04 mg/L (Aesthetic), 0.4 mg/L (Health-based limit)
  • Nitrate-N: 11.3 mg/L as NO₃-N (to prevent Blue Baby Syndrome in infants)
  • pH: 7.0 – 8.5 (Recommended for drinking water)
  • Silica: No MAV, but scaling potential at high levels
  • Sulphate: 250 mg/L (Aesthetic, due to taste and potential laxative effects)
  • 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.

Is the water sample for a domestic dwelling that has it's own water supply?
If the water sample is from a shared water supply, what is the name (or registration number) of the water supply?
What is the sampling point the sample is being collected from?

Please fill in your details and we'll be in touch shortly about a trial.
