Summary

Site-specific multiple linear regression models were developed for one beach in Ohio (three discrete sampling sites) and one beach in Pennsylvania to estimate concentrations of Escherichia coli (E. coli) or the probability of exceeding the bathing-water standard for E. coli in recreational waters used by the public. Traditional culture-based methods are commonly used to estimate concentrations of fecal indicator bacteria, such as E. coli; however, results are obtained 18 to 24 hours post sampling and do not accurately reflect current water-quality conditions. Beach-specific mathematical models use environmental and water-quality variables that are easily and quickly measured as surrogates to estimate concentrations of fecal-indicator [...]

Purpose

Site-specific models for two beach sites are provided in this data report to be used for management decisions through the Great Lakes NowCast to quickly estimate concentrations of E. coli or the probability of exceeding the State bathing-water standard in recreational waters used by the public. In addition, data used to develop the models are provided. Performance of models to estimate water-quality conditions during an independent year (2019) are presented. All measured and calculated variables initially considered in developing the models are provided in a model archive.
