Groundwater contamination - EPA assessment area

Results from the groundwater monitoring network have now been published and the report is available in the Reports section on this page. The results show that groundwater (bore water) in parts of the EPA assessment area is contaminated with PFAS, arsenic and copper, and should not be used for any purpose. The EPA is planning to undertake additional assessment to further understand the extent of this contamination.

An environmental assessment is planned for early 2021, and until the contamination is better understood groundwater should not be used for any purpose. Most properties do not have access to groundwater.

At the conclusion of the environmental assessment the EPA is likely to propose that a groundwater prohibition area should be established.
