Preface The In Situ Remediation Integrated Program (ISRIP), instituted by the U.S. Department of Energy's Office of Technology Development, focuses research and development on the in-place treatment of contaminated environmental media, such as soil and groundwater, and the containment of contaminants to prevent them from spreading through the environment. Using in situ technologies to clean up DOE sites minimizes adverse health effects to workers and the public by reducing contact exposure. The technologies also significantly reduce the costs for cleanup by eliminating the need for waste excavation, transport, and disposal; and enable the remediation of relatively inaccessible areas, such as the deep subsurface and areas beneath structures. This document was prepared under the ISNP and describes technologies in one of four program areas within the ISRIP. The four program areas are in situ physicalkhemical treatment technologies, bioremediation, containment technologies, and in situ manipulation/enabling technologies. In situ physicalkhemical treatment technologies address processes that will remove or extract, destroy, and immobilize contaminants. The bioremediation area includes biological processes to destroy organic contaminants and mobilize or immobilize heavy metals and radionuclides. Containment technologies encompass both surface and subsurface barriers, as well as sorbent or permeable barriers and drainage systems. The in situ manipulation/enabling technologies include those technologies that will enable the addition, mixing, and transfer of reagents or energy into the subsurface, and those that can be used to monitor and measure the performance of in situ technologies. These documents summarize the current state-of-the-art for each program area and the research and development requirements to advance the technologies to the point of demonstration and deployment. These documents will be used by the ISRIP as planning guides and will be revised and updated annually.
