Water makes the difference between living and non-living things, base on this there is a strong need to look at the chemistry, to make sure that it is free from contamination because of chemical reaction that take place in the living cell. In the case of this study, it is critical to determine the quality of the water supplied, because of the chemical reaction. This study analyzes 10 representative well water systems for 18 quality parameters in Kakua Chiefdom of Bo District, Sierra Leone. The study note among others, well-water total dissolved solids (TDS), turbidity, electrical conductivity (EC), coliform and nitrate (NO3-), in the region that are fairly high. The incidence of coliform in well waters is highest in April and those iron (Fe2+) and nitrate in May. The Dipha street well is amongst the most contaminated and TDS, Non-faecal and fluoride (F-) have the highest scores in a three-category plot along wells. Correlation analysis among the water chemistry shows an interesting results; ranging strong positive (R=1.0) to strongly negative (R=-1.0).
Key words: Physico-chemical, parameter chemical parameters, bacteriological parameters, water molecule.
