Oils, bacteria, mud, heavy metals and litter. These are some of the pollutants identified in the 2010/11 Stormwater and Rivulet Monitoring Program as washing into the Derwent estuary via urban rivulets and pipes. The program explored specific stormwater issues in each municipality and assessed the performance of stormwater management strategies to improve water quality for the protection of rivulets and the estuary. The results from this monitoring program were compared to previous years (2002 - 2005) to track changes in pollutant levels over time.
