摘要

Lead-zinc mines in the Viburnum Trend of southeastern Missouri are dewatered during mining operations. Although the mines are located in the Bonneterre Formation of the St. Francois aquifer, and this aquifer by the St. Francois confining unit, there is concern that pumpage for mine dewatering may have or possibly could lower water levels in the Ozark aquifer regionally. Also, a reduction in the flow of water to area springs and streams and lower water levels in area wells could result. Pumpage for mine dewatering is estimated to have been 26 million gallons per day in 1971 and was reported to be 27 million gallons per day in 1999.
