The EPA commenced an environmental assessment in Somerton Park in June 2023.
Information provided to the EPA identified chemicals (chlorinated hydrocarbons) in the groundwater and soil vapour (the air spaces within the soil) at a nearby site.
The EPA is undertaking an environmental assessment to understand if there is a risk that contaminated groundwater or soil vapour is impacting nearby residential properties.
More assessment is needed to understand the extent and potential health risks associated with this contamination, including from vapour intrusion.
Vapour intrusion occurs when chemicals in the soil or groundwater migrate to the indoor air above. The EPA will be undertaking additional assessment in March 2024.
