Testing frequency and reading levels

We monitor water quality at Wherowhero Lagoon every month throughout the year.

Soluble nutrient pollutants from fertiliser applications on surrounding farmland and animal manure, along with the dumping of rubbish into the lagoon and septic tank overflows have left the lagoon area in a poor state of health.

Thankfully an ecological restoration project has been established to enhance this invaluable wetland environment.
