Course Reviews (4.8/5): 
Overview: This course provides participants with an improved and updated understanding of petroleum hydrocarbon remediation science and effective technologies for soil, vapor, and groundwater. Topics covered include new science, key principles, and lessons learned in the field to establish a modern paradigm for petroleum site assessment and remediation. The course includes an in-depth discussion of practical and effective remediation technologies and their appropriate implementation. The applicability, strengths, and weaknesses of each remediation technology will be discussed. The primary focus of the training is the cleanup of gasoline releases. However, information presented will be applicable to other petroleum fuels and release types. Case studies will be presented to illustrate key concepts and potential challenges associated with petroleum remediation. A brief overview of less common remediation technologies is also included in the course material for additional reference.
