Ecological Systems Approach to Protect and Restore Sustainable Water Quality and Water Quantity on a Watershed Basis.
                    Science for Environmental Protection: The Road Ahead
 The National Research Council was recently tasked by EPA to assess the agency's capabilities to develop, obtain, and use the best available scientific and
 technological information and tools to meet persistent, emerging, and future mission challenges and opportunities. The NRC was also asked to identify
 and assess transitional options to strengthen the agency's capability to pursue and use scientific information and tools.
 The Ground Work Is In Place: The committee concludes that EPA is well equipped to take advantage of many scientific and technological advances, and,
   in fact, its scientists and engineers are leaders in some fields.
 The Road Ahead: Though the NRC Committee on Science does not have a crystal ball, it identified some common drivers and characteristics of problems
   that are likely to occur in the future. The report outlines key research to address current and future needs, such as research to understand: persistent
   and future environmental challenges with complex feedback loops; the effects of low-level exposures to numerous stressors (as opposed to high-level
   exposures to individual stressors); and, social, economic, and environmental drivers. The report also highlights the importance of systems thinking for
   devising optimal solutions. The report underscores the growing need for cross-disciplinary training and the need to expand capacity in social and
   information sciences. The report concludes that EPA will continue to need leadership in traditional core disciplines (statistics, chemistry, economics,
   environmental engineering, ecology, toxicology, etc.). EPA's future success will depend on its ability to address long-standing environmental problems;
   to recognize and respond to emerging challenges; to link broader problem characterization with solutions; and to meet the scientific needs of policy-
   makers and the American public.
