Broad-scale assessment of urban stormwater issues in the Waikato Region

To identify and assess the importance of potential adverse effects of urban stormwater in a range of receiving waters in the Waikato Region, including urban streams, small lakes, the Waikato River at Hamilton and estuarine embayments (at Raglan and Tairua). Purpose: To identify and assess the importance of potential adverse effects of urban stormwater in a range of receiving waters in the Waikato Region.

Modelled estimates of the future rate of accumulation of heavy metals (Pb, Zn, Cu) in assessed embayments in Raglan and Tairua Harbours, and assessment of the environmental effects of such accumulation.

inland sites plus sites at Raglan and Tairua Harbours.
