Introduction This lecture and field seminar will focus on natural attenuation surveys, degradation of chlorinated compounds, RBCA sampling and enhanced passive remediation technologies. Natural attenuation consists of microbial degradation processes that destroy petroleum hydrocarbons aerobically and anaerobically.
Degradation is frequently limited due to insufficient electron acceptors.
The presence or absence of electron acceptors and nutrients, water quality trends, the presence of petroleum hydrocarbons through time, the existence of hydrocarbon degraders will be evaluated to determine natural attenuation potential for hydrocarbon degradation. New in-situ technologies relating to chlorinated compounds will also be discussed. In addition, several compounds will be discussed to enhance natural attenuation. Instructors James A. Jacobs is the Chief Hydrogeologist for FAST-TEK Engineering Support Services, a firm which specializes in rapid site characterization and passive remediation systems. He has managed hunderds of site investigations.
