Drinking water: probably a private well

No community water system’s service area covers the center of ZIP 68642, and no system lists it. In rural areas that usually means private wells. The EPA does not regulate private wells: owners should test once a year for coliform bacteria and nitrate, and every few years for arsenic, lead, uranium and other local concerns. Your county health department can recommend a certified lab.
