Evaluation of soil washing process to remove mixed ...

Abstract Soil washing is a remediation process which is primarily used to treat soils and sludges which are contaminated with only one or two groups of contaminants (e.g., metals and/or volatile organic compounds). This process, however, has not been extensively employed on soils that are contaminated with pesticides in addition to metals and volatile organic compounds.
