A groundwater contamination plume with peak concentrations of the herbicides 2,4-D and 2,4,5-T of up to 180 mg/ L and 60 mg/L, respectively, occurs in the Kwinana industrial area near Perth, Western Australia. Drilling and sampling in 1989 and 1990 have indicated that contamination is largely restricted to a shallow sand aquifer, and that the underlying limestone aquifer is mostly unaffected. Contaminants may be undergoing microbial degradation at the margins of the contamination plume in the sand aquifer. This groundwater contamination incident occurred before the current Western Australian Environmental Act came into force, and responsibility for investigating and managing such contamination is vested in several Western Australian State Government agencies. There is currently no centralised resource pool in Western Australia to carry out investigations of groundwater contamination .
