The high percentage of agricultural land use in the Upper Wapsipinicon River Watershed intensifies ground and surface water quality issues in the watershed. The interactions between surface and groundwater and the vulnerability of groundwater is demonstrated in a survey of state well test results associated with thousands of private wells in Iowa. Data is provided by the Private Well Tracking System organized by the Iowa DNR through a public records request. The survey, conducted by the Environmental Working Group and the Iowa Environmental Council found that nitrate, coliform bacteria and fecal coliform bacteria were confirmed in thousands of wells across Iowa between 2002 and 2017. The study notes that both contaminants have serious impacts on public health and that not all wells are tested. A map developed through the research shows that the Upper Wapsipinicon  River Watershed is located in an area of Iowa that has documented significant numbers of contaminated wells, particularly by bacteria.

The Upper Wapsipinicon River Watershed is fairly new to surface water quality monitoring at the whole watershed scale. The Upper Wapsipinicon River Watershed Management Authority started water sampling with the help from partner organizations in 2015. Since then, samples were gathered in 2016, 2017, and currently in 2019. Due to lack of funding and volunteers no samples were collected during the 2018 season. Currently in 2019, samples are collected twice a month during May and June (on the first and third Monday of the month) and once a month (on the third Monday) from July to October. Samples are gathered from 22 locations across the UWRW. This data provides a snapshot of the entire watershed on a given day each month and allows the comparison of one stream/watershed to the next. For example, watersheds of streams in Howard County can then be compared and contrasted with similarly-sized watersheds that empty into the Upper Wapsipinicon 100-miles downstream in Jones County. Water samples are collected on the same day by 7 public and private organizations including, Buchanan SWCD, Buchanan County Conservation, Iowa State Extension, NRCS, Linn County Conservation, Black Hawk County Health Department, and Chickasaw County Conservation. Once samples are gathered they are packed on ice, and sent to the Coe College laboratory for analysis. The samples are analyzed for concentrations of E. coli Bacteria, Nitrate, Total Phosphate as P, Chloride, Sulfate, and Total Suspended Solids.

Continued data collection over a wide spatial area of the UWR Watershed allows for a better understanding of the water quality problems in the Watershed, and allows landowners, citizens and organizations to find ways to solve the issues related to poor water quality. Extensive water monitoring data can result in increased funding for effective watershed projects, bringing tens of millions of dollars in state and federal cost share to help private landowners implement voluntary conservation practices, as well as funding for SWCDs and other organizations to hire conservation professionals, including technicians and engineers, to provide free technical assistance to watershed residents.
