Chlorinated Degreasing Solvents: Physical-Chemical Properties Affecting Aquifer Contamination and Remediation

Many chlorinated degreasing agents have been formulated as multicomponent liquids that contain chlorinated hydrocarbons (such as trichloroethylene, perchloroethylene, or 1,1,1-trichloroethane) and a range of organic additives that serve as corrosion inhibitors and antioxidants. These additives are c...

Description
Summary:Many chlorinated degreasing agents have been formulated as multicomponent liquids that contain chlorinated hydrocarbons (such as trichloroethylene, perchloroethylene, or 1,1,1-trichloroethane) and a range of organic additives that serve as corrosion inhibitors and antioxidants. These additives are considered a public health concern with respect to groundwater contamination due to their high toxicity, solubility, and mobility. Following use, such chlorinated degreasing solvents may also contain some 25% of solubilized oil and grease. Several behavioral phenomena that may result from differences in the physico-chemical characteristics of the diverse contaminants contained in used chlorinated degreasing agents are highlighted. Recommendations for remediation planning are proposed.
