What is Water Testing?

Water is at the core of our business. Not only are we responsible for testing drinking water for more than one third of New Zealand’s population, but we are a division of Watercare Services – the fifth largest company in New Zealand by asset value. Watercare provides high quality drinking water and efficient wastewater services to 1.7 million customers every day. 

Our expert team provide water service providers, local government authorities, businesses, and residential customers with comprehensive testing of drinking water, wastewater, stormwater, trade waste, environmental and recreational waters. Our testing is carried out to the highest international standards by experienced professionals working right here in New Zealand.

Water Testing Capabilities

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.

Nutrients

Nutrients—especially nitrogen and phosphorus—are key water quality parameters in environmental water. They can have significant direct or indirect impacts on plant growth, oxygen concentrations, water clarity, and sedimentation rates. 

Inorganics

Inorganic chemistry deals with synthesis and behaviour of inorganic and organometallic compounds. This field covers chemical compounds that are not carbon-based. 

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.

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). 

PFAS

PFAS is an emerging organic contaminant and is an increasing area of focus in environmental management given it’s link to adverse health effects.

Continuous Water Monitoring

Online monitoring is a major improvement in many types of water monitoring, the ability to view real time trends and changes over time gives a much more detailed view than discrete (grab) sampling.
