In the basement complex, the aquifers usually exist under water table conditions because they are unconfined while the sedimentary basins show greater complexity because water may be obtained from more than one horizon in a vertical profile. This study examines the effect of waste and the environment on the quality of groundwater of the sedimentary formations and basement complex of part of Ogun State, Nigeria. Samples of water were taken from Water Corporation, borehole water, water sold in sachets and well waters from the geologic areas under study with Water Corporation sample serving as control experiment. In addition to this, the depths were measured to determine the depth of wells and ground water levels. Using grab method, representative samples were taken from the effluent from the industries, 3 wells at measured distances 288.20m, 468.30m and 1219.20m respectively from the point of discharge of the waste. The samples and effluent from the sedimentary formations and basement complex were, in line with APHA (1985), tested for physico-chemical and microbiological parameters and the results compared with available standards. The results revealed that the activities of the industries have tremendously affected the quality of groundwater in the basement complex area and, when the results from sedimentary formations were compared with acceptable standard, some were found to be suspects in terms of quality. In line with available and acceptable global practice, in order to prevent widespread of water related diseases, methods of reducing these parameters in the wells were recommended for the inhabitants.
