(1) The City of Cockburn, on request by the Department of Environmental Protection (DEP), have engaged a suitably qualified consultant to consolidate and analyse historical monitoring data collected at the site as part of its operating licence. The report is to be submitted to the DEP to determine whether the landfill is having any impact on the environment or off-site. Comments made by the City of Cockburn on previous monitoring reports indicate that salt water intrusion has been identified at bore MP2. This may explain the elevated levels of chloride and total soluble salts. This will be the subject of further analysis by the City of Cockburn in its report to DEP. (2) No, there is no correspondence relating to exceedences of Environmental Protection Authority Drinking Water Guidelines. However, the DEP has met with representatives of the City of Cockburn to discuss issues relating to annual monitoring requirements.
