EPA assessment area
The EPA commenced environmental assessments in Brighton in February 2018, after soil vapour contamination from tetrachloroethene (PCE) was identified during the redevelopment of a commercial site.
The work found PCE in soil vapour across the assessment area (please see map below). The work also found that the source of the PCE contamination is likely to be a dry cleaning premises on Brighton Road. As a result the person who caused the contamination is responsible for future work.
In order to assess whether there is any risk of PCE entering into residential properties, further work is required. The EPA is regulating the liable person to undertake this work. The EPA has recently issued a site contamination assessment order (SCAO) to the liable person to require further assessment work. The issue of a SCAO is consistent with the Environment Protection Act 1993. The order requires soil, soil vapour and groundwater assessment work to commence in September with reporting expected in December 2018. Engagement of an Site Contamination Auditor to undertake a site contamination audit report (SCAR) is also a requirement of the order. The audit system provides for the highest possible assurance for the community in relation to the protection of human health and the environment where site contamination exists or may exist. Failure to comply with an order is an offence under the Environment Protection Act 1993. The EPA will ensure residents are kept informed as this work progresses.
Groundwater (bore water) in this area may be contaminated and should not be used for any purpose. Mains water supplied by SA Water is not affected by this issue. Home grown fruit and vegetables are safe to consume, provided they are not watered with bore water.
