Recreational Water Quality Criteria: Report of the Experts Scientific Workshop

Report of the Experts Scientific Workshop on Critical Research Needs for the Development of New or Revised Recreational Water Quality Criteria (EPA 823-R-07-006; June 2007)

EPA 823-R-07-006; June 2007

The March 2007 Experts Scientific Workshop was a forum for discussion of critical research and science needs for developing new or revised recreational ambient water quality criteria in the near-term. Forty-three U.S. and international experts from academia, numerous states, public interest groups, EPA, and other federal agencies met to talk about the state-of-the-science on recreational water quality research and implementation.

This report summarizes the discussion of the scientific and technical panel in the following topic areas:

• Approaches to criteria development
• Implementation realities
• Pathogens, pathogen indicators and indicators of fecal contamination
• Methods development
• Comparing risk (to humans) from different sources
• Acceptable risk
• Modeling applications
