Green River, Wyoming

Located in the southwestern part of Wyoming, Green River serves as the county seat of Sweetwater County and has a population of approximately 13,000. Green River was originally part of the Dakota Territory, and was the starting point of John Wesley Powell’s famous expeditions of the Green River, Colorado River, and Grand Canyon. On May 5, 1891, Green River was officially incorporated as a city.

Green River did not experience much growth until the turn of the 20th century, when the railroad was forced to move a division point into Green River’s center. The population grew and in 1938, trona ore was discovered in the city’s Green River Basin. Trona is mined as a hydrated ore and processed to produce sodium carbonate, an important industrial chemical. Industry took advantage of Green River’s abundance of trona and capitalized on its availability. FMC (Food Machinery and Chemical Corp) opened a production facility and mine in Green River, and maintains operations there today. Other companies attracted to the city’s plethora of trona include Allied Chemical Station and Stauffer Chemical Company. The mining of trona remains the most economical means of obtaining sodium carbonate in the United States, although most international companies have transferred to a synthetic process.

Green River’s longstanding industrial and manufacturing history places the city in a high risk category for asbestos exposure. If you were exposed to asbestos in Green River, Wyoming, you may benefit by seeking counsel from an asbestos lawyer.
