Overview: This course provides a practical overview of contaminant behavior in soil and groundwater with an emphasis on petroleum, chlorinated hydrocarbons, and metals. The material is intended for consultants and regulators managing contaminated sites. The course begins with an overview of contaminant transport and fate, chemical partitioning, and hydrogeology; and concludes with focused sections on the fate and transport of petroleum hydrocarbons, chlorinated solvents, and metals.
