Roger Young: Cawthron Institute scientist on New Zealand's freshwater quality report

It's thought New Zealand's achievement of water quality targets hinges on every Kiwi getting behind efforts. 

A new report has evaluated four contaminants —nitrogen, phosphorus, E. coli, and sediment— in rivers, lakes, and estuaries nationwide. 

Every region needs a substantial reduction in at least one to meet freshwater standards. 

75% of land is contributing more E. coli to water than is allowed. 

Cawthron Institute scientist, Roger Young, told Tim Dower that achieving targets could require land-use changes in some areas and mitigation work in others. 

He says in those cases, fencing and wetlands enhancements and protections could be enough.
