EPA assessment area
The EPA is undertaking environmental assessments in Brighton, where soil vapour contamination from tetrachloroethene (PCE) was identified during the redevelopment of a commercial site.
The source of the contamination has not yet been found. However the contamination is believed to be the result of past industrial or commercial activities. Chemical disposal and handling practices that were considered appropriate decades ago, are no longer acceptable by today’s environmental standards.
These chemicals, once released into the environment, move down through the soil and into groundwater (bore water). The chemicals then dissolve into the water and also become a vapour above the water. The presence of the chemical vapour in soils is called ‘soil vapour’.
Over time, the chemicals move naturally with the groundwater, sometimes over very long distance.
The movement of soil vapour occurs when the chemical vapour moves up through air spaces in the soil. The vapour can then enter into buildings through a process known as ‘vapour intrusion’. In order to determine whether soil vapour intrusion is occurring in the Brighton assessment area, the EPA is undertaking work to gather more data to understand the composition of the soil vapour, the possible source of the contamination and whether any additional assessment work is required.
The EPA is planning to install up to 20 temporary soil vapour bores, which will be drilled on street verges within the assessment area. These bores are used to measure soil vapour.
Groundwater (bore water) in this area is likely to be contaminated and should not be used for any purpose. Mains water and rainwater are not affected by this issue and home grown fruit and vegetables are safe to eat providing they are not watered with contaminated bore water.
