Abstract

This study investigates the chemical concentration of borehole water in Yola-Jimeta Metropolis so as to assess their suitability for domestic use. Water samples were collected from twenty-two boreholes, one sample from each of the twenty-two administrative wards (Wards are the lowest political units in Nigeria) in the metropolis. Samples were analyzed in the laboratory using standard guideline procedures suggested by American Public Health Association (APHA). Eleven contamination indicators were tested and results obtained were compared with chemical guideline values for drinking water provided by World Health Organisation (2011) and Standard Organisation of Nigeria (2007). The study reveals that chloride (Cl-), iron (Fe++), nitrate (NO3-), pH, sodium (Na+) and total hardness (CaCO3) are the main sources of borehole water contamination in the study area. This has health implications that include hypertensions and heart and kidney diseases which are on the increase in the region. Poor sanitary condition and intensive use of inorganic fertilizer are implicated as sources of contaminants. We therefore suggest the setting up of water sanitary agencies that will monitor and regulate health based targets of water quality at ward levels.
