Trichloroethylene and methyl chloroform in groundwater: A problem assessment

The national effort of past decades to reduce pollution has made great strides on some fronts, while practically ignoring potential disasters on others. Billions of dollars have been expended to equip and operate air pollution control systems, such as electrostatic precipitators, SO, scrubbers, and catalytic converters. Similarly, water pollution control has seen tremendous investment in both the industrial and municipal sectors, including advanced waste treatment practices for phosphorus removal, nitrification and denitrification facilities, and tertiary organic removal via carbon adsorption. Groundwater pollution remains a problem of immense importance, and only recently have methods been developed to help decontaminate polluted wells. With the advent of environmental awareness, giant leaps have been made in analytical techniques for the detection of compounds in air and water at very
