Routine Environmental Monitoring
Orica has been conducting routine monitoring of groundwater and soil vapour emission around the Car Park Waste Encapsulation (CPWE) since 1997 as part of its management program.
Soil Vapour Emission Monitoring
At the request of the NSW Department of Environment, Climate Change and Water, (now the Office of Environment and Heritage, OEH), soil vapour emission monitoring around the CPWE is reported together with the Air Emissions Sampling Program for Botany Industrial Park (BIP) and surrounding areas under Orica's Botany Groundwater Cleanup Project. Sampling is scheduled on a 15-month cycle.
During the sampling round that commenced in December 2010, sampling was not undertaken in the vicinity of the CPWE as its remediation was underway and the surface of the CPWE had been removed. The remediation of this emission source will mean that further sampling at the site of the CPWE should not be required.

Groundwater Quality Monitoring
Orica conducts a groundwater monitoring program around the perimeter of the CPWE. The program is consistent with instructions of the Australian and New Zealand Environmental and Conservation Council's (ANZECC) Hexachlorobenzene Waste Management Plan. It also satisfies Orica's requirement under its Environmental Protection Licence (No. 2148).
Groundwater quality monitoring is currently required on a six-monthly basis and is related to the identification of hexachlorobutadiene (HCBD) and related compounds within groundwater in the vicinity of the CPWE. The tables section of the reports listed below contains all monitored data since 1997.
N.B. - Older reports are available upon request. Please note that Tables from each report provide a summary of all historical monitored data.
