The report provides an evaluation of the water resources in a Wyoming Creek basin before the start of large-scale coal mining. It contains maps, graphs, and tables.

From introduction: The objective of this study are to (1) determine the areal extent and thickness of the Buffalo aquifer and the general occurrence of deeply buried aquifers, (2) determine the potential for development of water supplies from wells in the Buffalo aquifer, (3) investigate and discuss annual recharge to the Buffalo aquifer and the potential for artificially recharging the aquifer, (4) determine the chemical quality of water in the aquifer and in area streams, (5) establish a network of observation wells for monitoring water levels and water quality in the aquifer, (6) determine the relationship between the aquifer and the adjacent streams, and (7) update the information on the flow characteristics of the streams. The main focus of this study is on water in the Buffalo aquifer and on flow characteristics of streams.

From introduction: The specific objectives of the study were to: (1) Determine the premining hydrologic and geochemical conditions in the 28 mi2 area; (2) provide a premining data base from which to measure the magnitude of change in the hydrologic system due to coal mining; and (3) determine the probable effects of mining on the water resources in the area.

Purpose and scope: The purpose of this report is to describe and make preliminary interpretations of: (1) Limnological characteristics of Williams Lake, based on physical, chemical, and biological data collected in 6 days in 6 different months in 1979; (2) chemical quality of ground water near the lake, based on samples collected during the summer of 1979; and (3) mineralogy of the lake sediment cores obtained in February 1978. The period of study extended from March, when the lake was covered by ice, through the period of open water, to December, when it was again covered by ice.

From abstract: This report provides water users with detailed information on the location, quantity, and quality of water available from underground coal mines in the Breathitt Formation of Pennsylvanian age in part of eastern Kentucky. The principal coal seams mined are the Van Lear in Johnson County and the Alma in Martin County. Coal mines that contained water were located by field inventory and coal-mine maps.

From abstract: This report uses chemical and bacteriological data to "describe the quality of water from selected geologic units in Routt County, Colorado.

This report evaluates and appraises the lignite reserves found in Lauderdale County, Tennessee. It includes maps and tables.

This report presents changes in water quality in an alluvial aquifer near Greeley, Colorado. It contains maps, graphs, and tables.

From introduction: In 1975 a project was begun to provide information on several aspects of coal hydrology in Ohio. The first phase was a reconnaissance of water-quality conditions in coal-mining regions. Phase one had two primary objectives; to document the occurrence of certain inorganic and organic constituents in waters of the coal-mining regions and to determine if the concentrations of those constituents were related to coal mining. The second phase of the project was a more detailed study of four basins sampled during the first phase.
