The U.S. Geological Survey, In cooperation with the City of Seward, Nebraska, conducted a study of ground-water age and quality to improve understanding of: (1) travel-times from recharge areas to public-supply wells, (2) the effects of geochemical reactions in the aquifer on water quality, and (3) how water quality has changed historically in response to land-use practices. Samples were collected from four supply wells in the Seward west well field and from nine monitoring wells along two approximate ground-water flow paths leading the well field.
