Abstract

One normal episode of pump operation in domestic wells drilled into bedrock in New York typically lasts about 1 minute and lowers the water level about 1 meter. Measurement of water levels in the pumped well before and during pumping and recovery can be completed in 2 to 3 hours and requires negligible disturbance of the well, so can be easily arranged. Such a test involves less turbulent flow or well loss than longer tests, and can be conveniently analyzed by a new computer program. Tests of 25 wells completed in shale, siltstone, or sandstone in the Appalachian Plateau of New York have been analyzed by this program and by two alternative methods, all of which yield similar transmissivity values and are equally insensitive to storativity.
