Risk Assessment studies that rely on mean exposure levels and ignore dynamic environmental features such as source water pathogen concentration and drinking water treatment levels, may not provide accurate risk estimates. In this study, we developed a methodology to characterize the fluctuations in source water quality due to rainfall driven norovirus loadings, applied to a river case study modeled on the Ohio River. Two important dynamic processes which affect the exposure to human enteric viruses are investigated: rainfall driven Combined Sewer Overflows (CSO); and drinking water treatment.
