In 1991, members of local, State, and Federal governments, as well as industry and interest groups, formed the Ground-water and Pesticide Strategy Committee to prepare the State of Wyoming’s generic Management Plan for Pesticides in Ground Water. Part of this management plan is to sample and analyze Wyoming’s ground water for pesticides. In 1995, the U.S. Geological Survey, in cooperation with the Ground-water and Pesticide Strategy Committee, began statewide implementation of the sampling component of the State of Wyoming’s generic Management Plan for Pesticides in Ground Water. During 2005–2006, baseline monitoring was conducted in Niobrara and Weston Counties. This Fact Sheet describes and summarizes results of the baseline monitoring in Niobrara and Weston Counties.
