Mal Green (SEL) and Chris Cornelisen from Cawthron Institute reviewed ecologically relevant thresholds for informing marine water-quality standards to support the review of the Waikato Regional Coastal Plan. The standards related to a number of areas including eutrophication, water-column sediments, water temperature, microbial contaminantion, toxicants, emerging contaminants; oil, grease, litter and other gross pollutants. It also identified options for defining standards and requirments for assessment options.
