Organic contamination of the Birmingham aquifer, U.K.

摘要: Abstract A survey of the organic-water quality Birmingham Triassic Sandstone aquifer was conducted using 59 supply boreholes. Additional shallow-groundwater data were obtained from 15 monitoring wells. Chlorinated solvents are widespread, in particular trichloroethylene which is detected 78% Trichloroethylene frequently observed at high levels with 40% boreholes contaminated above 30 μg/l to a maximum 5500 μg/l. Occasional values also found for 1,1,1-trichloroethane and perchloroethylene. The distribution shown be controlled by land use hydrogeological factors. Contamination organic chemicals other than chlorinated low When contamination does occur it usually form petrogenic hump unresolved contaminants chromatogram. source such probably (degraded) lubricating oils. Greater general seen shallow groundwater samples, reverse trend results.
