The 33.5-acre Muscatine Power and Water (MPW) Coal Combustion Residue (CCR) Landfill has been in operation since 1985 and is located about 7 miles west of the Mississippi River. The landfill stores a mixture of gypsum, fly ash, bottom ash, and slag from MPW's three coal-fired electric generating units.
