Literature review of the risks and adverse effects from waterborne contaminants in Otago

Streamlined Environmental (SEL) undertook a review of existing information to identify contaminants present in discharges from stormwater, human wastewater, industrial and trade waste, and other potentially hazardous activities (such as agricultural and mining practices) in the Otago Region. An SEL team, including Freeman Environmental (Trade Wastes), worked collaboratively with ORC staff to provide this first step in a risk assessment process to assess the potential impact these discharges may have on sensitive receiving environments in the Otago region and inform future changes to Regional Plans (Water, and Coast).
