Water is the difference between living and non-living and water for drinking should be pollutant free. Thus in supplies for urban and rural consumption, water quality is one of the most critical parameters to verify. Well and/or open-water systems are easily liable to anthropogenic contaminations, the source of most water-borne epidemics especially in developing countries like Sierra Leone. This study analyses 10 representative well-water systems for 18 water quality parameters in Kakua Chiefdom of Bo District, Sierra Leone. The study notes that well-water quality parameters such as total dissolved solids (TDS), turbidity, electrical conductivity, coliform and nitrate (NO3−) are fairly high above safe drinking water standard. The incidence of coliform in the well waters is highest in April and that of iron (Fe2+) and nitrate is highest in May. The Dipha Street well is amongst the most contaminated and has the highest scores for TDS, non-faecal coliform and fluoride (F−). Correlation analysis shows an interesting bond among the water quality parameters, ranging from strongly positive (R = 1.0) to strongly negative (R = −1.0). Fe2+ is strongly positively correlated with most of the well-water quality parameters. Irrespectively, the use of contaminated water in domestic and/or agro-industrial sectors could pose various health risks and epidemic outbreaks of different intensities.
