Toxic chemicals in an abandoned phenolic waste site

The nature and extent of pollution was determined at the site of a former pinetar manufacturer. Compound distributions at various areas about the site revealed that, in addition to groundwater leaching of soluble phenolics, insoluble contaminants were spread by a dike-breach incident and subsequent construction activities. Differences in the patterns of chemicals in various wells suggested that more than one source of pollution occurred. The distribution of compounds about the site indicated that a general clean-up would not be cost-effective. Placement of an interceptor to collect groundwater seepage that contaminates surface water is being considered as an alternative.
