As a result of the drinking water standards for viruses established by the United States Environmental Protection Agency in 1985, mandatory groundwater disinfection requirements were recently proposed. A variance from this requirement might be granted if the community meets several criteria, including conducting a vulnerability assessment of the source water. The purpose of the vulnerability assessment will be to determine whether there are potential sources of microbial contamination located in the area that may negatively impact the microbiological quality of the groundwater. This paper discusses the factors that affect the fate and transport of microorganisms in soil and groundwater. Models that have been developed to predict the potential for microbial contamination of groundwater are presented.
