This collaborative project between RMIT University and Melbourne Water will develop ecological tools for assessing pollution risks and impacts in freshwater streams around Melbourne. Pollutants in waterways that are impacted by untreated sewage and stormwater inputs will be screened and then tested in the laboratory using standardised ecotoxicological tests. Field microcosms and caging experiments will be used to assess in situ impacts. It is envisaged that this project will lead to the development of new biological tools for pollution assessment, including but not limited to microbial indicators, fish and macroinvertebrate indicators and plant function indicators.
