Our waste water testing capabilities range from influent characterisation through to the final effluent quality testing, and includes sludge and air quality tests.

Influent and final effluent characterisation

We analyse process samples for a range of different parameters, including:

• Biochemical oxygen demand (BOD)
• Chemical oxygen demand (COD)
• Dissolved oxygen
• Metals
• Nitrate
• Nutrients to check the efficiency of a nutrient removal plant
• Oil and grease to check for saponification
• Sludge volume index
• Suspended solids
• Volatile solids
• Sludge analysis

We analyse sludge for:

• Arsenic
• Cadmium
• Chromium
• Copper
• Cryptosporidium
• Enteric viruses
• Faecal coliforms
• Giardia
• Helminth ova
• Iron
• Lead
• Mercury
• Nickel
• Nitrogen
• Organo-chlorine pesticides
• pH
• Phosphorus
• Potassium
• Salmonella
• Zinc

Landfill testing

Landfill operators are required to monitor sludge parameters in order to minimise their effect on the landfill environment. We operate a wide range of equipment and test methodologies to cover Ministry for the Environment landfill testing criteria.

Land disposal testing

In some areas of New Zealand, land disposal remains the only alternative to effluent discharge. We offer a nutrients analysis service for foliage and piezometers to monitor the effect of discharge on ground and surface waterways.

Data reporting

We are able to provide data in multiple formats to integrate with our customers’ systems. Automation of this process allows for simplification and minimisation of transcription errors, and ensures data is readily available for a range of consent conditions.
