Groundwater Embargo Area Management Zones

Main contaminants What are Chlorinated Hydrocarbons? Chlorinated hydrocarbon (CHC) is a generic term given to chemical compounds containing chlorine, carbon and hydrogen. The term can be used to describe pesticides such as lindane and DDT, industrial chemicals such as polychlorinated biphenyls (PCB), chlorine waste products such as dioxins and furans, and dry-cleaning products such as PCE. How did CHCs contaminate the Botany Groundwater? It is suspected that they came from: –The former Solvent Plant –The former EDC storage tanks –The former TCE Plant –The former CTC/PCE storage tanks –The former Open Heavy Ends Drums Storage Area –The former Effluent Treatment Plant Overflow Area –The former re-drumming areas adjacent to the Heavy Ends Drums Storage Area.
