Predicting recreational water quality advisories: A comparison of statistical methods Predicting recreational water quality advisories: A comparison of statistical methods
Epidemiological studies indicate that fecal indicator bacteria (FIB) in beach water are associated with illnesses among people having contact with the water. In order to mitigate public health impacts, many beaches are posted with an advisory when the concentration of FIB exceeds a beach action value. The most commonly used method of measuring FIB concentration takes 18–24 h before...

Human and bovine viruses and bacteria at three Great Lakes beaches: Environmental variable associations and health risk Human and bovine viruses and bacteria at three Great Lakes beaches: Environmental variable associations and health risk
Waterborne pathogens were measured at three beaches in Lake Michigan, environmental factors for predicting pathogen concentrations were identified, and the risk of swimmer infection and illness was estimated. Waterborne pathogens were detected in 96% of samples collected at three Lake Michigan beaches in summer, 2010. Samples were quantified for 22 pathogens in four microbial categories...

Organic waste compounds as contaminants in Milwaukee-area streams Organic waste compounds as contaminants in Milwaukee-area streams
Organic waste compounds (OWCs) are ingredients and by-products of common agricultural, industrial, and household substances that can contaminate our streams through sources like urban runoff, sewage overflows, and leaking septic systems. To better understand how OWCs are affecting Milwaukee-area streams, the U.S. Geological Survey, in cooperation with the Milwaukee Metropolitan Sewerage...

River chloride trends in snow-affected urban watersheds: increasing concentrations outpace urban growth rate and are common among all seasons River chloride trends in snow-affected urban watersheds: increasing concentrations outpace urban growth rate and are common among all seasons
Chloride concentrations in northern U.S. included in this study have increased substantially over time with average concentrations approximately doubling from 1990 to 2011, outpacing the rate of urbanization in the northern U.S. Historical data were examined for 30 monitoring sites on 19 streams that had chloride concentration and flow records of 18 to 49 years. Chloride concentrations...

Human and bovine viruses in the Milwaukee River Watershed: hydrologically relevant representation and relations with environmental variables Human and bovine viruses in the Milwaukee River Watershed: hydrologically relevant representation and relations with environmental variables
To examine the occurrence, hydrologic variability, and seasonal variability of human and bovine viruses in surface water, three stream locations were monitored in the Milwaukee River watershed in Wisconsin, USA, from February 2007 through June 2008. Monitoring sites included an urban subwatershed, a rural subwatershed, and the Milwaukee River at the mouth. To collect samples that...

From streets to streams: Assessing the toxicity potential of urban sediment by particle size From streets to streams: Assessing the toxicity potential of urban sediment by particle size
Urban sediment can act as a transport mechanism for a variety of pollutants to move towards a receiving water body. The concentrations of these pollutants oftentimes exceed levels that are toxic to aquatic organisms. Many treatment structures are designed to capture coarse sediment but do not work well to similarly capture the fines. This study measured concentrations of select trace...
