Surface water and sediment were sampled in a snapshot study at six sites in four industrial drains in the Perth area for a range of contaminants. The sites monitored in this study were all in drains from catchments that are dominated by industrial land uses.
There is a diverse range of industries in each catchment, with different waste and stormwater management practices making it difficult to determine the source(s) of contamination. Potential sources, other than industry, include septics, road runoff, bushfires and fertiliser application on residential properties, parks and reserves.
