PRECIOUS METAL REFINERY, Newburn, Swan Coastal Plain, Western Australia, WA Investigation, risk assessment, remedial design, groundwater contamination


A phased groundwater investigation was undertaken of impacts from leakage of gold refinery effluent at the Perth Airport. An initial hydrogeological audit reviewed site operations, historical spillages & existing monitoring data, leading to the development of a phased
investigation program.

An EM34 geophysical survey broadly defined anomalous areas of contrasting electrical conductivity. A bore investigation & sampling
program identified the extent of a groundwater contaminant plume comprising excess electrical conducitvityEC, acidic pH and a variety of metals in particulate & dissolved forms extending approximately 400m west from the refinery.

The plume was impacting a surface water & groundwater flood control drain. Sampling of surface waters & sediments in conjunction with
consultants ERS at regular intervals identified an impact zone over an approximate 250m length, where metal concentrations exceeded applicable environmental guidelines.

A detailed groundwater & surface water monitoring program was initiated, together with a risk assessment study, including:

-Ecological assessment of the impact zone & downstream areas
surrounding the drain
-Sampling exercise to determine downstream surface water
-A surface water management plan to prevent or minimise
effluent discharges
-A numerical groundwater modeling and contaminant transport simulation exercise to assess the significance of plume
-contribution to surface water quality and the potential for natural
-A metal ecotoxicology assessment in conjunction with CSIRO

The risk assessment program will identify the
requirements for the implementation of a future
remedial action plan.
