Federal regulators have approved a Nebraska list that raises the number of impaired waters to 330 in the state.
The Environmental Protection Agency said Monday that the Nebraska Department of Environmental Quality submitted a list that removed 21 bodies of water and added 92, bringing the total to 330.
The list is required of each state by the federal Clean Water Act.
The act requires the EPA to review the state lists to determine whether the states reasonably considered available water quality data.
The EPA says the lists set priorities for reducing sources of water pollution.
A Nebraska water body is placed on the list when pollutants prevent the lake, river or stream from being used for recreation, agricultural water supply and maintaining aquatic life.
