Eurofins New Zealand is experienced and with the analytical requirements for all stages of the delivery of potable/drinking water, having been closely involved in the New Zealand Water Sector for over 20 years. These range from Sampling to extensive testing suites for councils and manufacturers of bottled water right down to farm and householder water supplies.

Private Drinking Water Testing 

Our Domestic Water Suite has proven particularly popular with homeowners looking to test their drinking water quality. Our clear report format details how sample results compare to standard limits and what these results mean. This takes the guesswork and confusion out of the process and provides peace of mind.

This suite of tests is one which homeowners can use to determine the quality of their water supply by measuring a wide range of likely contaminants including:

  •          E. coli (and Total Coliforms)
  •          Chloride, Sulphate and Nitrate
  •          Arsenic, Boron, Calcium, Copper, Iron, Magnesium, Manganese, Potassium, Silica, Sodium and Zinc
  •          Total Hardness
  •          pH, Conductivity, Turbidity and Alkalinity

Public Water Supply Testing

Water quality must be assessed at source and monitored throughout the source, treatment, reticulation, and distribution systems in order to guarantee its quality and to comply with current and proposed New Zealand legislation.

We work with a number of councils around New Zealand to sample, test and report data; we currently export thousands of data per month into WINZ, the national Water Information New Zealand database, on behalf of all our regular potable water clients. This is an automated system that reduces errors and maximises time-saving. Our clients are able to report this data directly from WINZ in their own office enabling considerable savings of time and resources.

We also provide electronic data files for direct download into other client databases. Once again, this process is automatic and involves no manual manipulation.

We analyse source water, treatment plants and reticulated water supplies for a wide range of analytes, including:

  • E. coli
  • Metals
  • Fluoride and other anions
  • Semi-Volatile and Volatile Organic Compounds
  • Pesticide residues
  • Protozoa such as cryptosporidium and giarida
  • Taste and Odour compounds such as geosmin, 2-Methylisoborneol and 2,4,6-Trichloroanisole

Other Potable Water Testing

For companies and individuals looking to investigate the quality of their water supply, we offer three different suites of tests as recommended by expert panel of the New Zealand Drinking Water Standards (NZDWS). The suites have been established by laboratory and water treatment experts and are designed to test surface and groundwater to provide water quality information for clients not intending to treat their supply, through to more comprehensive suites that provide the information necessary to set-up treatment systems.

This includes laboratory testing of the following:

  •          Bottled water
  •          Farmhouses with bore water sources
  •          Holiday homes using roof water collection
  •          Ice
  •          Mineral Water Used for Bottling
  •          Rural supplies receiving tankered water
  •          Small Community and Individual Drinking Water Supplies
  •          Urban reticulation systems
  •          Water Tankers
  •          Workplaces
