| The purpose of this paper is to convey useful information gained from approximately 10 years of development and deployment of in situ thermal treatment (ISTT) technologies. This paper is the result of a series of in‐depth interviews with U.S. EPA Remedial Project Managers (RPMs) and On‐Scene Coordinators (OSCs) and with ISTT vendors whose experience extends beyond federal response action sites to include state‐regulated cleanups and Brownfields/voluntary cleanups, as well as international projects. While the focus is on federally funded cleanup sites, many of the lessons learned will be of interest to RPMs and OSCs who are overseeing potentially responsible party (PRP)-lead cleanups. |
