Research Supporting Development of the 2012 Recreational Water Quality Criteria

Critical Path Science Plan

The Critical Science Plan describes the overall research goals, key science questions associated with data gaps in the existing science, and the studies that EPA intends to conduct or support to develop new or revised water quality criteria for pathogens and pathogen indicators.

The Critical Path Science Plan was informed, in part, by the input on the essential research and science needs identified by 43 international and U.S. experts from academia, States, public interest groups, EPA and other federal agencies who attended a scientific workshop held by EPA in March 2007. EPA sponsored the workshop to get individual input from the greater scientific and technical community on the near-term research and science needs to develop new or revised Clean Water Act Section 304(a) criteria. All of the research activities included in the Critical Path Science Plan were identified in the Experts Report as high priority. EPA further prioritized the research activities identified by the experts so as to focus on only the studies that EPA believed could be designed, conducted and effectively incorporated into the development and publication of new or revised criteria within a reasonable time frame.

The projects and activities below represent high priority research and science that EPA conducted to establish the scientific foundation for the development of new or revised recreational water quality criteria recommendations. Full descriptions of each project and others can be found in the Critical Path Science Plan.

Epidemiological studies below were part of the National Epidemiological and Environmental Assessment of Recreational Water (NEEAR).

* Projects were not completed due to contingencies identified in the Settlement Agreement.
