Safety, Health and Environmental Management Plan for Works within the Botany Basin Groundwater Extraction Exclusion Area

From time to time, Orica receives enquiries about undertaking subsurface works (e.g. dewatering or excavation of site) in areas around the Botany Industrial Park, and the management of Orica-related contamination found in soil or groundwater on the properties. Orica has prepared a generic document that contains some safety, health and environmental (SH&E) information to assist owners/operators of properties within the Botany Basin Groundwater Extraction Exclusion Area (GEEA) (or Zone 1 of Botany Sands Aquifer Management Area as set out by the NSW Office of Water) in undertaking such works. As this is a generic document only, it must be customised and updated by the user to meet the needs and constraints of specific works to be undertaken at the specific location, associated hazards and risks, as well as any changes in legislation and knowledge related to contamination.

Distribution of Contamination Plumes in Shallow Groundwater

For images of the inferred distribution of contaminated shallow groundwater in the Botany Basin GEEA, refer to below. These figures are extracted from the quarterly Groundwater Cleanup Plan Progress Report. Each of these figures shows the concentration of a particular contaminant measured at the shallowest well screen/port of each of the sampled monitoring locations (the figures are updated annually; the most recent figures are derived from the groundwater monitoring event in June 2009):

• Distribution of chlorinated hydrocarbons in shallow aquifer  (751 KB)
• Fig 5.2 - 1,2-Dichloroethane (EDC) 
• Fig 5.3 - Tetrachloroethene (PCE) 
• Fig 5.4 - Trichloroethene (TCE)
• Fig 5.5 - Vinyl Chloride (VC)
• Fig 5.6 - Carbon Tetrachloride (CTC)
• Fig 5.7 -Chloroform (CFM)
