Homeowners in this mid-size Missouri city receive their tap water from a network of multiple local systems that maintain a generally favorable quality profile.

While the city's overall water quality is solid, residents should keep in mind that runoff from the surrounding agricultural heartland is a constant factor for local water managers to address.
