WATER TESTING

All Clear’s analytical suites have been selected based on our experience and knowledge of the common contaminants associated with your specific water supply. Results will be assessed against relevant guidelines set out by the Ministry of Health (Drinking Water Standards New Zealand 2018 and Household Water Supplies 2019). Please contact us to request a quote and a full list of the parameters we will test for. We do have the ability to include a range of other parameters and contaminants for an additional cost at your request also.

All Clear’s water quality assessment includes the collection of samples from one location, typically where you are most likely to obtain water from (e.g. kitchen tap). From this location we will collect 3 samples for the different parameters we test for (Microbiological analysis, Basic Water Chemistry Analysis and Metals and Minerals analysis).

Additional sample locations can be requested during the assessment for an additional cost.

Regular testing is important to:

• Identify any existing contaminants.
• Ensure water it potable and suitable for intended use.
• Track changes over time. The quality of a water source may change over time, even suddenly. Changes may go unnoticed, as many contaminants are odourless and colourless.
• Determine the effectiveness of a treatment system.

We can test all types of drinking water supplies including bore water, spring water, rainwater or mains supplied water. There is also additional suites designed for recreational water usage such as our spa pool / swimming pool suite and pond water suite.

Drinking water contaminants are often colourless and odourless and can go undetected until consumers begin to feel unwell. Poor water quality may cause diseases particularly gastrointestinal related with symptoms such as diarrhoea and vomiting. In more severe cases nervous system, reproductive issues or chronic diseases such as cancer may result from contaminated water. Self-supplied water is often untreated and could become contaminated at any point in time so regular monitoring and a good treatment plan is essential to ensure your drinking water is safe.

If you are a registered drinking water supplier with Taumata Arowai you have obligations under the Water Services Act 2021 to regularly test your water and prepare a drinking water safety plan. All Clear can assist with carrying out your drinking water tests to meet these requirements.

The current safe level for Nitrates outlined in the New Zealand Drinking Water Standards, as mandated by the World Health Organization (WHO) is, 11.3mg/L but many think this is too high! Research completed by Dr Tim Chambers from the Department of Public Health at the University of Otago, Wellington indicates that nitrates in drinking water could be causing up to 100 bowel cancer cases and 40 deaths in New Zealand every year and that many New Zealanders are regularly drinking water containing levels of nitrate which may put them at increased risk of bowel cancer. Nitrate cannot be detected in water by taste or smell so it is important to test your water supply especially if you have a self-supplied water system.
