Bellevue web 2016Bellevue—on site remediation is about
to begin.

Background

On 15 February 2001, fire destroyed a liquid waste treatment and recycling facility at 1 Bulbey Street, Bellevue. The facility operator, Waste Control Pty Ltd, subsequently went into receivership and the State is now the registered owner of the site.

Soil and groundwater investigations have found a broad range of contaminants including petroleum hydrocarbons and chlorinated solvents, which can be attributed to historical site operations, the fire and fire-fighting water runoff.

A second source of trichloroethene, a chlorinated solvent, was also identified between the site and the Helena River.

In the first phase of remediation, a permeable reactive barrier (PRB) was installed in 2010, to intercept and treat contaminated groundwater before it reaches the Helena River.

 

LandCorp has been appointed by the Department of Water and Environmental Regulation (DWER)* to manage the contamination at Bellevue’s former Waste Control site and restore it for future industrial land use consistent with City of Swan zoning (general industrial use). For updates on the Bellevue Remediation project, visit LandCorp’s website.

* The former Department of Environment Regulation amalgamated on 1 July 2017 with the Department of Water and the Office of the Environmental Protection Authority, forming the Department of Water and Environmental Regulation.

What Is Happening Now?

The clean-up of the offsite source of trichloroethene near Stanley Street, commenced in June 2016. The technology being used is a form of enhanced in-situ bioremediation in which emulsified vegetable oil and specialised bacteria are injected into the soil to break down the contaminants. The success of the bioremediation will be determined by performance monitoring over three years.

On the Bellevue site itself, work has begun on removing the concrete slabs and services from the site and will be followed by excavating affected soils where necessary and transporting them for disposal at an appropriate landfill. An Environmental Management Plan will be in place throughout the works and includes dust monitoring during the excavation work.

The clean-up works are overseen by an independent Contaminated Sites Auditor and will be subject to extensive monitoring to ensure the safety of workers and the environment.
