Groundwater Contamination by Trichloroethene (TCE) in a Residential Area of Perth: Distribution, Mobility, and Implications for Management

摘要: Substantial TCE and ammonia contamination was detected in groundwater beneath a residential area Perth. Investigation has successfully determined broad aspects of the extent plume its impact. The extends approximately 900 m downgradient an industrial area. is about 300 wide 6 - 8 thick. A peak concentration 2000 ugL{-1} measured. mobility residence time for sand aquifer are estimated based on velocities retardation factors. Biological or chemical transformation cannot be excluded, although no products have been found small portion plume. Currently remediation contaminated site planned. An approach managing presented important issues future options sites Perth discussed.
