Maintain a healthy water supply with comprehensive water testing

Safe, clean drinking water is essential for good health. When it comes to testing drinking water, we are experienced and trusted in the field. In fact, we test drinking water for more than a third of the population of New Zealand. Our laboratories are registered with Taumata Arowai and internationally accredited, which means our testing is comprehensive and reliable. We have been testing drinking water for more than 50 years, and we pride ourselves on being a New Zealand owned and operated laboratory service testing drinking water for New Zealand. 

We can test drinking water from the following sources: ground, bore, spring, lake, creek, rain, mains network.

What do we test for?

Metals

Our inorganic trace metals department uses the latest ICP-MS technologies to detect trace metals in waters, soils, dust filters, and shellfish biota. Working out of a custom-built laboratory that has separate areas for sample preparation, instrumental analysis, and administration, the site provides optimum conditions for low level analysis of metals.

Drinking water suites

Our laboratory offers a general suite of tests based on your water supply (bore, rain, tank, spring, creek etc.) this includes a mixture of general chemistry, microbiological and metals tests. These suites have been designed to give you an overview of your current water quality.

Microbiology

Microbial testing is necessary where human health is at risk of being adversely affected by biological pathogens, disease-causing bacteria, and other toxins.

Anions

Using an ion chromatograph, our general chemistry department can detect an extended range of anions at low detection limits. Flow analysis instruments also allow the team to offer customers anion testing across both saline and environmental samples.

Organics

Organic chemistry deals with the structure, properties, composition, reactions, and preparation of carbon-containing compounds. Most organic compounds contain carbon and hydrogen, but they may also include any number of other elements (e.g., nitrogen, oxygen, halogens, phosphorus, silicon and sulfur).
