The presence of pathogen indicators is the leading cause of water body impairment in the United States, accounting for over 15% of the waters currently requiring TMDL development (USEPA, 2005). Contributions of nonpoint sources of contamination (stormwater) to these receiving waters are of particular concern. Recent studies have indicated that indicator organism and/or pathogen concentrations often increase substantially following runoff-producing storm events (Atherholt et al. 1998;Characklis et al. 2005; Dai and Boll, 2003; Jamieson et al. 2005; Jeng et al. 2005;Krometis et al.). Additionally, heavy precipitation events have also been linked to elevated prevalence of waterborne disease (Curriero et al. 2001; Rose et al. 2001). Identification of stormwater events posing a threat to public health and remediation of waters currently listed as contaminated is limited by current models of microbial transport.
