Owens, D.W., Hunt, R.J., Firnstahl, A.D., Muldoon, M.A., and Borchardt, M.A., 2019, Water-quality data collected for Kewaunee County, Wisconsin: U.S. Geological Survey data release,


We deployed a sampler to characterize water quality from a household well tapping a shallow fractured dolomite aquifer in northeast Wisconsin. The sampler was deployed from January to May 2017, and monitored temperature, nitrate, chloride, specific conductance, and fluorescent dissolved organic matter on a minute time step; water was directed to sequential microbial filters during three recharge periods that ranged from 5 to 20 days. Results from the automated sampler demonstrate the dynamic nature of the household water quality, especially with regard to microbial targets, which were shown to vary 1 to 2 orders of magnitude during a single sampling event. We believe assessments of pathogen occurrence and concentration, and related [...]

The purpose of this study was to design, construct, and test an automated sampler suited for hydrogeologically and chemically dynamic groundwater systems. Pathogen occurrence in groundwater varies considerably in space and time, which can be difficult to characterize as sampling typically requires hundreds of liters of water to be passed through a filter. Water moving through the sampler was monitored using water-quality sensors, including temperature, specific conductance, pH, nitrate, chloride, fluorescent dissolved organic matter (FDOM), and turbidity using a multi-probe water-quality sonde and a flow-through chamber to characterize the dynamics and conditions of the household system during time periods when pathogen samples were taken. The purpose of this data release is to make the chemistry and microbial data collected during this study available to interested readers.
