In December 2020, the EPA commenced investigations into site contamination from tetrachloroethene (PCE), trichloroethene (TCE) and other chemicals in groundwater and soil vapour (the air spaces between soil particles) at a former dyers and dry cleaners site.
The results of the Stages 1 and 2 work to date confirm groundwater within the assessment area should not be used for any purpose.
Soil vapour contaminated with PCE and TCE may have the potential to enter into indoor air in one home at low concentrations. Testing of indoor air was undertaken at 1 property that recorded concentrations within safe levels and this resident has been contacted directly.
The work undertaken in September 2021 involved the installation and sampling of additional groundwater and soil vapour bores.
Residents have been advised that further seasonal testing of soil vapour and groundwater will commence in the streets around the former dry cleaner site in January 2022. The results from the September 2021 testing will be combined with the work to be undertaken in January 2022, to produce a comprehensive Stage 2 report.
At the conclusion of its environmental assessments the EPA is likely to recommend that a Groundwater Prohibition Area be established.
