Data were collected to evaluate the efficacy of quantitative polymerase chain reaction (qPCR) as a rapid, alternative method for monitoring recreational water at select beaches and rivers of Sleeping Bear Dunes National Lakeshore (SLBE), in Empire, Michigan. Water samples were collected between August 4 and September 18, 2014 (N=297) from four locations (Esch Rd, Otter Creek, Platte Bay, and Platte River). The samples were analyzed for indicator bacteria, E. coli and enterococci, by both culture-based (membrane filtration, MF; traditional method) and non-culture based (qPCR; rapid method). Recreational water quality standards (RWQS) and beach action values (BAV) were used as indices to compare water quality standard exceedances for MF and qPCR methods; for enterococci: 70 colony-forming units (MF) and 1,000 calibrator cell equivalents and for E. coli: 235 colony-forming units (MF); currently, there are no established RWQS based for qPCR (i.e., CCE) results. The CultureBasedData data include E. coli and enterococci culture-based bacterial counts. Data from the qpcr_v3 file includes results from quantitative polymerase chain reaction (qPCR) method for estimation of E. coli and enterococci counts by DNA-based methods. The Lat_Long file includes information regarding sampling sites at each of the four locations and their corresponding latitude and longitudes.

In 2016, a multidisciplinary team from the U.S. Geological Survey Wyoming-Montana Water Science Center, National Park Service, The Centers for Disease Control and Prevention, and Montana State University’s Department of Microbiology and Immunology in cooperation with the Teton Conservation District, initiated a small study to document the presence or absence of Naegleria fowleri at several hot springs in Grand Teton National Park/John D. Rockefeller, Jr. Memorial Parkway. Over four sampling events in 2016-2017, Naegleria fowleri was detected in several of the Grand Teton National Park/John D. Rockefeller, Jr. Memorial Parkway hot springs for the first time. Additionally, the team found that the prevalence of Naegleria fowleri may be subject to seasonal fluctuations.

This data set is a comma-separated values (CSV) file containing continuous hourly water quality observations of the Salmon River in Glacier Bay National Park and Preserve for monitoring years 2010-2022. The core parameters collected are water temperature, dissolved oxygen, pH, and conductivity, obtained from multiparameter sondes during the ice-free season. Using the Aquarius Time-Series application, data have been quality controlled, graded against formal criteria specified in the protocol (SOP 7, Data Evaluation and Grading in Aquarius), drift corrected where appropriate, and certified for publication. The data set (CSV) and associated metadata are zipped into a site-specific archive (ZIP file), identified as the FQ_Q deliverable in the water quality protocol.
