Abstract: It has been established by researchers that cost of installing hand-dug well for water generation for human consumption is of low cost and affordable by many people compared to bore holes water cost. The level of water quality needs assessment before consumption. In this study, ground water quality (hand dug-well water) was assessed and its suitability for drink ability was compared with Nigeria Industrial Standard (NIS) for water drinking quality in Akure city, Nigeria. Samples as-received (initial sample) and treated sample were taken to laboratory for analysis. Certain physical, chemical (organic and inorganic) disinfectants and micro-biological constituents in the water samples were examined before and after the treatment of the water samples to determine the water quality for domestic consumption. Laboratory analysis of water parameters also disclosed the fact of significant contamination in ground water, since, the initial water sample has colour, odour and taste. The initial sample has total coliform count higher than NIS standard which is an indication of faecal contamination whereas the treated sample was found within acceptable limit. Therefore, the water needs to be treated before consumption. The pH value for the treated water sample (5.8-7.5) was slightly acidic and fairly neutral. Other chemical inorganic parameters such as aluminum, arsenic, barium, hardness and so on are found to be within the specified standard for the treated sample. Treating the water before drinking will be appropriate to the consumer to reduce any water health challenge.
