Over recent years, the use of in situ thermal technologies such as electrical resistance heating, thermal conductive heating, and steam enhanced extraction to remediate contaminated sites has notably increased. The U.S. EPA's latest (13th) green remediation "BMP fact sheet" describes processes, equipment, and analytical tools that can be used to reduce the environmental footprint of applying these technologies, which typically involves significant energy consumption. The best management practices (BMPs) address other core elements of a greener cleanup: reducing air pollutants and greenhouse gas emissions, reducing water use and negative impacts on water resources, improving materials management and waste reduction efforts, and protecting ecosystem services. The BMPS may be used during design, construction, operation and maintenance, and/or monitoring of an in situ thermal project.
