VI UNDERGROUND COAL MINES AS SOURCES OF WATER FOR PUBLIC SUPPLY IN NORTHERN UPSHUR COUNTY, WEST VIRGINIA By W.A. Hobba, Jr. ABSTRACT The northern part of Upshur County in Most mine water requires some central West Virginia primarily uses the treatment. Water from flooded mines near Buckhannon River as a source of public Buckhannon is moderately hard, slightly water supply. Current (1961) water use of acidic, and generally contains excessive 1.6 million gallons per day exceeded the amounts of iron, manganese, and hydrogen flow of the river measured during a sulfide. Water from wells in the vicinity drought period in 1930 by as much as 1.46 of the ml TIPS is chemically similar to million gallons per day. Three flooded water from mines. However, after contin underground mines the Buckhannon River uous pumping of a flooded mine by the mine, the Miller-Todd mine, and the Minear mining company, the dissolved mineral load mine located about 6 miles south of increased, and specific conductance was Buckhannon at Adrian were considered as a reported to have increased from about 400 source of municipal water supply during to 3,000 micromnos at 25 C. time of drought.

Population is increasing in northern have been insufficient for five of these Upshur County (fig. 1.1-1), an area months for the 1981 water needs of the served by the Buckhannon public water area (table 1.1-1 and fig. 1.1-2). The system. The water system is currently flow of the river for the 4-month period being expanded to serve a larger part of of August through November 1930 is 411 the county.

Thus, a water supply County, city, and regional planners are of 2,380 gal/min plus the entire flow of concerned that, should a drought occur, the river would be required to supply the the available river water would not meet necessary water for the system. The flow minimum demands. For example, the aver of the river for the 3-month period of age daily flow of the river in August September through November 1953 is 244 through November 1930 and in September Mgal less than the projected water demand through November 1953 was less than the for the year 2018.
