Abstract

This study assesses the heavy metals and the microbiological parameters of waters from hand dug wells and water boreholes in Ogba, Egbema, Ndoni Local Government Area, Rivers State, Nigeria. The study involves fifteen borehole water samples and fifteen water samples from hand dug wells, making a total of 30 groundwater samples collected from November to December, 2022. Heavy metals and biological parameters analysed includes Lead, Iron, Chromium, Copper, Cadmium, Mercury, Arsenic, Biological Oxygen Demand and E. coli and their quality characteristics evaluated by comparing them with WHO, 2012 water quality standards. The results from the analyses of boreholes samples yielded parameters that met the requirements provided by WHO, with exception of Pb, Cd, and E. coli. While Pb, Cd, as and E.coli in hand dug well water did not meet the recommended guideline. Heavy metals were found to have higher concentration in water boreholes than hand dug wells and could be as a result of the discharge of effluents from the oil companies and materials from anthropogenic sources. But samples of E.coli were higher in hand dug wells than water boreholes which could be attributed to poor sanitation causing water contamination from anthropogenic activities. It is therefore recommended that a proper waste management system should be provided and maintained for proper environmental sanitation in the study area, this will minimize indiscriminate dumping of waste and will reduce percolation of pollutant into groundwater.
