A spatially intensive approach to water quality monitoring in the Rous River catchment, NSW, Australia
- Southern Cross Univ., Lismore, New South Wales (Australia). Centre for Coastal Management
The Rous River catchment northern NSW, Australia was used as a case study to evaluate a spatially intensive approach to water quality monitoring, which involved the collection of water quality data from a large number of sample sites over a short period of time. Despite a few potential limitations, the spatially intensive water quality monitoring methodology should allow environmental managers to rapidly and cost-effectively (in the long term) identify point and non-point source impacts on water quality. Three point sources, the Murwillumbah Sewage Treatment Plant, a dairy shed and horse stables had the largest impact on water quality in the Rous River catchment during baseflow conditions. The poorest water quality in the Rous River catchment, due to non-point source inputs, was associated with cane land, which had evaluated total nitrogen, total particulate nitrogen, and dissolved organic nitrogen concentrations and temperatures that were significantly greater (Kruskai-Wallis, {proportional_to} {gt}0.05) than other land uses.
