英文摘要	The potential cumulative water quality impacts of expanded future coal use in the United States was investigated under the National Energy Plan (NEP). The NEP calls for nearly doubling of coal production and use over the next ten years. A surface water quality model was developed to estimate regional water quality impacts. The quantity of pollutants expected to be discharged as a result of coal extraction, coal-fired steam electric power generation, and industrial coal use was characterized in detail for individual sources with specific control requirements that take into account regional differences. From the pollutant loadings, the model calculates the incremental impacts based on dilution capacity of streams. It is concluded that, although water quality impacts from industrial coal use are expected to be greatly reduced due to the enactment of recent environmental laws, intense development of coal mining and coal-burning facilities may cause water quality problems in a few areas, notably the Upper Ohio River Basin, the Northern Great Plains, and the Upper Colorado River Basin. Judicious siting of coal mines and coal-burning facilities is needed to avoid adverse water quality impacts in areas where stream assimilative capacity is limited. Improved mine-sealing techniques for reducing acid mine drainage from underground mines in the East are also required. Additional critical water quality issues demanding close attention are: (1) leaching and migration of trace elements contained in uncombusted coal residuals; (2) acidification of water resources resulting from increased emissions and deposition of sulfur dioxide and nitrogen oxide; and (3) local and regional water quality problems resulting from reduced surface water dilution capacity due to increased water consumption.
