With appropriate monitoring, intrinsic bioremediation can be a successful treatment strategy if the rate of contaminant destruction outpaces contaminant migration such that the contaminant plume shrinks over time without causing a significant threat of exposure. Thus, it is considered appropriate for the USGS to participate in We identification and solution of problems associated with remediation of contaminated land and water resources.

The range of options that has become available includes emerging concepts with bench-scale testing, field demonstrations, and techniques approved for full-scale use and commercialization. For example, the state of technology development for options applicable to soils, sediments, ground waters, and other matrices (Table 4.

Growing out of these integrations will be the need to understand the complex responses resulting from multiple processes, in order to more confidently evaluate the overall effectiveness of complex remediation schemes. OPPORTUNITIES FOR THE USGS The research challenges associated with remedial technologies represent an important avenue of opportunity for the USGS, because the experience and expertise required to assess and characterize the nation's water resources as impacted by hazardous materials are the same as those needed to successfully engage in the assessment of He effectiveness of remediation.

The Federal-State Cooperative Program supports specific site-related studies that are short term and may include site characterization and monitoring as well as the evaluation of remedial technologies. The evaluation of more broadly applicable field methods and techniques may be funded by the Department of Defense Environmental Contamination Program, whereas the Core Hydrologic Research and Toxic Substances Hydrology Programs provide long-term funding that supports scientific work with more prospective potential.
