Adelaide's south-west residents have received a warning from The Environment Protection Authority (EPA) against using toxic bore water.
Tests have revealed the water in the 30 registered bores in the region has been contaminated with chemicals from fuels including vinyl chloride and industrial solvents that had been once used to clean metals and as degreasers. A former industrial site that had used the then-existing waste disposal methods is thought to be responsible for this contamination.
The toxic levels were found to be above Australian Drinking Water Guideline values.
The Environment Protection Authority (EPA) had written to the more than 2200 residents of South Plympton and Edwardstown. It was carrying out further tests to identify the extent of the problem.
Chief executive Helen Fulcher said that every step is being taken to protect the health of the community.
