Norovirus in Recreational Waters in Arizona
… of norovirus following exposure to contaminated recreational water have been documented, as swimmers and others engaged in water recreation often consume recreational water, either purposefully or accidentally, during their activities. In Arizona there have been several outbreaks of norovirus …

Bacteria Prediction For Recreational Waters Through The Use Of Artificial Neural Networks
… may also be present. These bacteria in recreational water bodies pose a health threat to people if ingested during activities such as swimming or from the consumption of marine life. The most commonly tested FIBs are total coliforms, Fecal coliforms, Escherichia coli, Fecal streptococci, …

Coliforms, Salmonella, and Shigella in the James River Basin
… the 200 CFU/100 mL EPA established limit for recreational waters. The median E. coli levels for 4 locations were above the 126 CFU/100 mL EPA established limit for recreational waters. Correlation analysis indicated bacterial levels are influenced by the flow rate and stormwater runoff, but …

Pathogen Indicator Monitoring In The Ross Barnett Reservoir
… million people visit the Reservoir each year for recreational purposes, including boating, fishing, water-skiing, and swimming. Protecting the water quality in the Reservoir is important for these visitors and inhabitants along the shoreline, and for these reasons, the U.S. Environmental …

Resin-based method for concentration of enteric viruses and F-RNA coliphages from water samples
Fecal contamination of source and recreational waters represents a public health concern due to potential content of human pathogens, and the variety of sources from which an individual may be exposed to such contamination. Enteric viruses such as noroviruses, rotaviruses, adenoviruses and …

Phenotypic and Genotypic Characteristics for Escherichia coli strains responsible for bacterial bloom events in Australia
… of recent faecal contamination of drinking and recreational waters. However, evidence suggests that E. coli can proliferate in the environment outside a host, confounding its use as a faecal indicator. E. coli strains that produce significantly elevated counts of 10,000 - 100,000 cells/100 ml of …

Evaluation, Development and Improvement of Genotypic, Phenotypic and Chemical Microbial Source Tracking Methods and Application to Fecal Pollution at Virginia's Public Beaches
… of fluorometry proved difficult in opens waters due to high levels of dilution, but showed potential for use in storm drains. An additional study developed and tested a new library-based MST approach based on the pattern of DNA band lengths produced by the amplification of the 16S-23S rDNA …

Microbial Source Tracking in a Mixed Use Watershed in Northern Virginia
… developing Northern Virginia region, contains watersheds of mixed rural and urban/suburban uses. As part of Virginia regulations, recreational waters must be tested and remain under a certain standard for levels of fecal indicator bacteria (FIB). The sources of fecal pollution in neighboring …
