Modeling and source-tracking tools for understanding fecal contamination and predicting recreational water quality at Ohio beaches

This project will be done at three Lake Erie beaches. Models   developed for Edgewater and Villa Angela, in Cleveland, during a   previous study need further refinement and testing. At a third   beach, Lakeshore Park in Ashtabula, beach advisories based on   elevated E. coli concentrations are often posted. The sources of E.   coli at Edgewater and Lakeshore are largely unknown. The application   of source-tracking techniques may help in identifying sources as   well as enhancing the development of predictive models.    The overall goal of the proposed work is to improve the science of   recreational water-quality monitoring and prediction. Specific   objectives to accomplish this overall goal are to:  - Refine and test existing MLR models for Edgewater and Villa   Angela, develop a new model for Lakeshore, and investigate the use   of ANNs for predicting E. coli concentrations at all three beaches.  - Identify the spatial distribution of E. coli at Edgewater and   Lakeshore so that possible sources of fecal contamination can be   identified.  - Test the use of source-tracking techniques, such as identification   of human enteric viruses and genotyping of F-specific coliphage, to   determine whether humans and (or) animals are significant sources of   fecal contamination at Edgewater and Lakeshore.  - Determine the relations between concentrations of E. coli in   sediments and interstitial waters collected from near the swash zone   to those in bathing waters at Edgewater.    (microbial source tracking); (MST); (bacterial source tracking);   (BST)
