Beverley and Woodville South
Since 2015, the EPA has been assessing groundwater and soil vapour in Beverley for historically used chemicals including trichloroethene (TCE). Beverley has a proud manufacturing history and some past chemical handling practices have contaminated the groundwater in this assessment area.
The EPA last wrote to residents in October 2017 providing results of the testing completed at that time. Previous correspondence, maps and reports are available from the links below.
Further testing is being undertaken in 2019 to understand the status of the contamination within the assessment area. Where vapour intrusion is affecting residential properties and subject to owner agreement, work will be undertaken to make indoor air at residential properties safe.
The EPA reminds residents that groundwater (bore water) in this area is contaminated and should not be used for any purpose. Contaminated groundwater generally does not contaminate the soil above it, unless it is a source site. Soil, rainwater, and mains water are not affected. Home-grown vegetables are safe to consume, provided you are not watering them with bore water.

In 2006, the EPA was advised of site contamination from TCE in groundwater at a former industrial site in Beverley. In 2007–08, the EPA and SA Health tested groundwater to determine the nature and extent of contamination in the surrounding area. Residents, landowners and businesses were contacted during this time.
In June 2008, the EPA in consultation with SA Health letterbox dropped approximately 3,000 properties including residents and businesses, advising them that bore water should not be used for any purpose in the assessment area.
Following a review in August 2014 the EPA and SA Health agreed that further testing of groundwater and soil vapour was required. In 2015, the EPA outlined a testing program which included soil vapour and groundwater testing.
Environmental testing confirmed the presence of trichloroethene (TCE) in groundwater and soil vapour at a number of locations within the assessment area.
Further, targeted soil vapour testing in a reduced area of interest was undertaken to better define the nature and extent of soil vapour contamination.
The EPA announced another round of soil vapour testing in two smaller, defined areas. This testing involved the installation of a series of permanent soil vapour bores at varying depths on public and commercial land along with the re-sampling of some existing locations to validate previous results.
Work in the area close to a source in Pope Street was undertaken to determine if there is a risk to human health from vapour intrusion into specific homes. This involved testing for vapour in yards, beneath homes and within the air inside homes at a number of residential properties in the assessment area. Work in the broader Beverley area was undertaken concurrently to the site specific works, to determine the extent of the contaminated groundwater plume and possible sources.
The most recent results are from October 2017, from the broader Beverley area. They are generally consistent with or lower than the previous risk assessment, which is considered to be due to seasonal moisture in the soil preventing vapour from migrating through the soil. The computer modelling predicted 16 additional properties in the 'investigation' range of the indoor air level response range (TCE), and 34 additional properties in the 'validation' range in the vinicity of new soil vapour bores.
All other properties in the investigation and intervention ranges have been previously identified and, where permission was granted, have had site-specific testing and/or mitigation work undertaken.
