National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Research on the Hydrology and Water Quality of Watersheds Subjected to Surface Mining. Phase I: Premining Hydrologic and Water Quality Conditions.

PB80159510

Publication Date	1979
Personal Author	McIntosh, G. E.; Harmon, W. R.
Page Count	40
Abstract	Five watersheds, ranging in size from 29 to 52 acres, were selected in east-central Ohio for the purpose of investigating the hydrologic and water quality conditions occurring before, during, and after surface mining. The average concentrations of the water quality parameters for all watersheds were as low as or lower than the Environmental Protection Agency recommended maximum allowable concentrations in drinking water except for suspended solids. Before mining the average concentration of suspended solids in storm runoff ranged from 118 to 1,100 micrograms/l, and for base flow the range was from 44 to 247 micrograms/l; the higher concentrations were associated with the watersheds exhibiting the greatest premining disturbance. Iron ranged from an average of less than 3 to 228 micrograms/l. Manganese ranged from less than 41 to 334 micrograms/l. Premining ground water systems for each watershed had two major perched aquifers within the top 250 ft.
