Water quality measurements at 3 beach sites in the Great Lakes from the summer of 2015: Edgewater Beach, OH; Grant Park, WI; Washington Park, MI. Data include associated environmental parameters (meteorological and hydrologic). Microbial data include cultured fecal indicator bacteria, coliphage, and molecular marker (qPCR) measurements. Detailed description of data collection activities can be found in Wanjugi et al. 2018: https://www.sciencedirect.com/science/article/pii/S004313541830349X.

Data consists of health and survey data from epidemiological studies at beach sites and water quality measurements. This dataset is not publicly accessible because: EPA cannot release personally identifiable information regarding living individuals, according to the Privacy Act and the Freedom of Information Act (FOIA). This dataset contains information about human research subjects. Because there is potential to identify individual participants and disclose personal information, either alone or in combination with other datasets, individual level data are not appropriate to post for public access. Restricted access may be granted to authorized persons by contacting the party listed. It can be accessed through the following means: Data can be accessed by request to Tim Wade: wade.tim@epa.gov. Format: Data are stored in comma delimited text files with codebooks in MS Word. This dataset is associated with the following publication: Benjamin-Chung, J., B. Arnold, T. Wade, K. Schiff, J. Griffith, A. Dufour, S. Weisberg, and J. Colford. Coliphages and gastrointestinal illness in recreational waters: pooled analysis of six coastal beach cohorts. EPIDEMIOLOGY.

Data were collected as part of a study to identify sources of E. coli contamination at several beaches located in the Grand Calumet River Areas of Concern, located in northern Indiana on Lake Michigan, as well as in Illinois and Wisconsin on Lake Michigan. Water samples were collected at each site in Indiana three times a week for thirteen weeks and at each site in Illinois and Wisconsin. All samples were analyzed for E. coli bacteria (an indicator bacteria for fecal contamination) and species-specific molecular markers (microbial source tracking, MST), including human, gull, and dog. Presence of MST markers indicates a fecal source at that location associated with the target animal. Field conditions were recorded during each site visit (e.g., including air and water temp, wind speed and direction, rainfall, wave height, currents, observations). Water samples were analyzed in the laboratory for E. coli using defined substrate technology and for MST markers using quantitative polymerase chain reaction (qPCR) methods and also turbidity. Lat_long_v2 file includes information regarding sampling locations and their corresponding latitude and longitudes. The E coli_turbidity_v2 data include E. coli densities and turbidity measurements. Data from the qpcr_v4 file includes results from quantitative polymerase chain reaction (qPCR) method for detection of host-specific microbial source tracking markers. Data from SanitarySurvey includes ambient conditions measured in the field: water and air temperature, current speed and direction (eastward, westward, float method), wind direction and speed, wave height, rainfall, and cloud cover. Data from SanitarySurvey_birds included number of birds (gulls, geese, ducks, cormorants, etc.) counted on the beach and in the water.
