EPA Superfund Program: UNION PACIFIC RAILROAD CO., POCATELLO, ID

Superfund Site Profile

The 1-acre Union Pacific Railroad Co. (UPRR) site is located in Pocatello, Idaho. The site is also known as the UPRR Sludge Pit site. From 1961 until 1983, UPRR dumped sludge from its wastewater treatment plant into a 1-acre unlined sludge pit. Site operations contaminated soil and groundwater with heavy metals and organic compounds. Contamination has been addressed and Amtrak currently operates a train station on site. EPA took the site off the Superfund program’s National Priorities List (NPL) in 1997.
