Stage 1 assessment results


Groundwater is contaminated

The results of the first stage of work has confirmed that the groundwater is contaminated with trichloroethene (TCE) in the assessment area and should not be used for any purpose (see the map available from the document library). TCE was widely used historically for metal cleaning and other purposes, and past chemical handling instructions were to tip it out onto the ground.

Indoor air may contain low concentrations in a small number of homes

There are no results confirming indoor air contamination, but a computer model has been used to predict which houses might need further testing. In a small number of homes, the EPA has asked residents if testing can occur on their property.

A copy of the report is available from the document library, and includes maps and figures showing the extent of the groundwater and vapour contamination. The full report is approximately 1,000 pages long, so if you would like a copy please contact the EPA:
