Full Description

The American Water Works Association Research Foundation and US Environmental Protection Agency have jointly funded a study of pathogen variation in US souce water. This paper describes the rationale and recommendations for the monitoring program design to be used in this study. The source water monitoring program is intended to support the following overall study objectives: evaluate the temporal variability of pathogens in source water, and those factors most strongly affecting this variability for a range of watershed conditions; assess monitoring program designs for various source waters to reliably generate high quality estimates of pathogen concentrations for key endpoints (mean, 90%ile, etc.); and, evaluate, at appropriate proof-of-concept levels, the use of hydrologic and watershed modeling tools to assist in the prediction of source water vulnerability to pathogens within a temporal framework. Includes 4 references, tables, figures.
