Ground-water resources of Olmsted Air Force Base, Middletown, Pennsylvania

Water Supply Paper 1539-H
By:  and 



Olmsted Air Force Base is underlain by the Gettysburg shale of Triassic age. The Gettysburg shale at the Air Force Base consists of interbedded red sandstone, siltstone, and shale. The average strike of the strata is N. 43° E., and the strata dip to the northwest at an average angle of 26°. The transmissibility of known aquifers in the warehouse area of the Air Force Base is low. Therefore, wells in the warehouse area have low specific capacities and yield only small supplies of water. Wells on the main base, however, yield relatively large supplies of water because the transmissibilities of the aquifers are relatively high. Pumping tests in the warehouse area and the eastern area of the main base indicated the presence of impermeable boundaries in both areas. Pumping tests in the central and western parts of the main base revealed that the Susquehanna River probably is acting as a source of recharge (forms a recharge boundary) for wells in those areas. Data obtained during this investigation indicate that additional supplies of ground water for Olmsted Air Force Base could best be obtained from the western part of the main base.
