Active remediation or "active remedy" means the remedial activities taken to reduce the mass, toxicity, mobility or concentration of a chemical of concern. Active remediation includes but is not limited to the removal of the hazardous substances or petroleum from the property or the design and installation of the following: air sparging; soil washing; pump and treat; steam stripping; soil vapor extraction; and enhancement of bioremediation. Active remediation may include short-term activities, such as soil removal and proper disposal, the construction of an engineering control, such as a cap, or ground water gradient reversal. Alternately, active remediation may involve long-term activities such as ground water pump-and-treat systems.
