Abstract Eleven test wells were drilled in the vicinity of Heflin in Cleburne County, Alabama to evaluate the interpretations and concepts developed in earlier geophysical studies conducted in 1966 and 1967. Quantites of groundwater adequate for municipal and industrial purposes were not found. Geological interpretations based on geophysical data were proved to be essentially accurate. Well yields in the Piedmont area are more closely associated with the degree of weathering and fracturing than with inherent differences in the mineralogical makeup of the rock. Fracturing, weathering, morphological stages, erosion, and the tectonic or structural history of each metamorphic or igneous rock unit may be distinct within a region. Therefore, identical rock types may produce distinctly different well yields in closely adjoining areas. Of the 11 test wells, 4 are 'dry', 3 will yield from 5 to 10 gpm, 3 from 10 to 15 gpm, and 1 about 30 gpm. Residual soils, talus and alluvium, and saprolite zones can be mapped by geological and geophysical methods. (WRSICabstract).
