Groundwater

Groundwater consumption is increasing due to high susceptibility of contamination of other sources. In this study, the consumption, contamination and management of groundwater resource in Isiohor quarters in Edo State were evaluated. A total of 300 questionnaires were randomly administered and laboratory analysis was carried out to determine the physicochemical parameters of the water samples collected. The results obtained showed that 94.7% of the respondents depend on groundwater as against 5.3% that use harvested rainwater.

Dumpsite utilization for municipal solid waste disposal produces leachate which is a threat to groundwater resources. The study was aimed at determining the suitability of groundwater for drinking and domestic usages using physical, chemical and microbial indices, with a view to assessing the vulnerability of boreholes close to dumpsite to groundwater pollution. The results showed that except for pH and lead, the concentrations of other physico – chemical parameters were within acceptable limits of NSDWQ and WHO.
