In November 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 Stage 1 work confirm groundwater within the assessment area should not be used for any purpose. At the conclusion of its environmental assessments the EPA is likely to recommend that a Groundwater Prohibition Area be established. Soil vapour contaminated with PCE and TCE may have the potential to enter into indoor air in one home at low concentrations. This property owner has been contacted to seek permission to undertake further testing. Should this indicate indoor air concentrations are present, the EPA will work with the residents to make their home safe.
Stage 2 work will involve installation and sampling of additional groundwater and soil vapour bores, and includes an expansion of the assessment area to the west, to determine the boundary of the contaminated groundwater and soil vapour plumes.
