In decades long since passed by, when industrial practices and regulatory oversight were a long way from being as advanced as they are today, chemical plumes within the groundwater under the industrial area were formed. These legacy plumes are an unfortunate part of our industrial history.
Much attention has been focused on managing the plumes over the past 20 or more years. In many cases it was deemed better to contain the plumes within their existing locations while biological processes reduced their extent, so that over time they may be fully eliminated. Other plumes require physical extraction and this is done via continuously pumping bores to extract the contaminated groundwater, and clean it up.
The overall purpose of remediation, whichever method is used, is to ensure that plumes do not reach Cockburn Sound via the normal groundwater flows.
