This OTA background paper evaluates the current state of knowledge and assesses the potential of bioremediation for responding to marine oil spills. Our basic message is a dual one: we caution that there are still many uncertainties about the use of bioremediation as a practical oil spill response technology; nevertheless, it could be appropriate in certain circumstances, and further research and development of bioremediation technologies could lead to enhancing the Nation’s capability to fight marine oil spills.

This report describes, documents, and analyzes available data about two key waste management problems at the Department of Energy Weapons Complex—those of high-level radioactive waste and transuranic waste. The paper is organized in two chapters—” Chapter 1: Managing High Level Waste’ and ‘Chapter 2: Managing Transuranic Waste. ” Each chapter contains a summary overview followed by a discussion and analysis of important areas in the waste management problem that the DOE faces at present and in its future operations.
