Recreational Water Quality Criteria
Report of the Experts Scientific Workshop
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
