Surface Water Reports 2013

Surface Water Quality - SoE Report

This report presents the 2010 - 2012 results of the monitoring carried out in rivers and stream across Marlborough. A new Water Quality Index has been used for the analysis of monthly measurement results. Five of the sites monitored have good water quality, but most sites have fair or marginal water quality. Some of the poor water quality is caused by the natural geology in the catchment, however, for the majority of sites the sources of deterioration in water quality are related to land use.
