Ground water Pollution can arise from percolation and infiltration of contaminants through the soil under waste disposal sites. This Study is aimed at accessing the microbiological quality of well water, its suitability for human consumption, as well as its closeness to pit latrine in densely populated settlements of Dala Local Government Area of Kano state, Nigeria. The depth from the ground surface to the static water level, vertical depth of pit latrines and soil infiltration layer were determined for all sampling points. Twenty four samples of well water were collected and transported to the laboratory for physico-chemical analysis and microbiological quality determination. Temperature of water samples at the time of collection ranged from 230c to 310c, with sample from Dala having the highest value (310c); that of Yalwa had the lowest temperature (230c). Water collected from the 12 sampling sites were contaminated with general and/or fecal Coliforms and E. coli at different levels; with exception of five (5) sample sites that had zero E. coli. Furthermore, it was generally observed that water samples which were in close proximity to the pit latrines had relatively higher microbial load. Therefore, well and pit latrine should be sited far away from one another and each should be well constructed to avoid any fecal contamination from the pit to the well water.
