ABSTRACT
I. SPILLS AT THE DEALERS' FACILITIES In this chapter we deal only with facilities that have been in operation for a number of years and where past practices probably have resulted in site contamination or in relatively new sites that have experienced a significant spill. It is assumed that minor spills at relatively new sites were cleaned up before any contamination left the site. Before deciding on a remediation procedure, the type and extent of contamination must be determined. To evaluate the type or types of contamination present will probably require a thorough site assessment to determine which raw materials have been used and products produced at the facility. All potential contaminants need to be identified. If more than one business had been at the site, this could require a more extensive investigation. Sampling of the soil and groundwater can then determine which chemicals are actually present, their concentration, and the extent to which they have penetrated the soil and groundwater. Selection of a suitable cleanup procedure can then be made from a number of options, such as (1) land farming, (2) pump-and-treat procedures, (3) soil washing, and (4) bioremediation, to mention a few. The proper cleanup procedure is generally designed specifically for each site and should be engineered by a knowledgeable remediation consultant in cooperation with regulatory authorities who have control over the particular situation. A list of environmental engineering companies is presented in World Environmental Directory (ISBN 0-9167 -4205-9).
