DEVELOPING MATHEMATICAL MODELS FOR PREDICTING Escherichia coli CONCENTRATIONS AT WISCONSIN BEACHES USING REGRESSIONS
The traditional methods to quantitatively determine Escherichia coli concentrations in beach water are the membrane filtration and defined substrate methods. These methods take 18-24 hours for enumeration of E. coli ...
Comprehensive sanitary survey evaluation of high risk beaches in northern Wisconsin
In 2008 13% of Great Lakes beaches exceeded health standards; approximately 90% of those exceedances were attributed to unknown pollution sources. In this project, sanitary surveys were conducted at all impaired beaches ...
MATHEMATICAL MODELS TO PREDICT Escherichia coli CONCENTRATIONS AT WISCONSIN BEACHES (MULTIPLE YEAR COMPARISIONS)
Beach water quality is determined using Escherichia coli as an indicator organism for fecal contamination. Traditional methods may result in improper beach closures and openings, as they base their decisions on previous ...
Cladophora promotes escherichia coli growth and contamination of recreational waters in Lake Michigan
In recent years, thick mats of the green alga, Cladophora, have washed onto beaches along Lake Michigan. These mats become stranded on the shoreline, begin to rot, and are malodorous. The rotting mats are a nuisance to ...
Detection of escherichia coli in northern Lake Michigan waters using qpcr method c
The defined substrate method, Colilert® (IDEXX, Westbrook, ME), is currently the most widely used method approved by the United States Environmental Protection Agency (US EPA) to detect Escherichia coli and total coliforms ...
