Marlborough region
River Quality
Water quality is monitored on a monthly basis at 34 sites as part of the region’s state of the environment (SoE) monitoring of surface water
Two of these sites, on the Wairau River, are monitored by NIWA. Sites are located at the bottom of catchments where possible in order to take account of the cumulative effects of land-use within the catchment. Land-use pressures in the region include dairying and exotic forestry in North Marlborough and viticulture and dry land pastoral farming in South Marlborough, particularly along the Wairau plains and east coast.
During the summer there is weekly monitoring at some sites. See the Marlborough District Council website for details.
