Investigation of borehole water contaminant profile at igwuruta solid waste dumpsite, Rivers State, Nigeria
Abstract
This study investigated the boreholes contamination profile at Igwuruta solid waste dumpsite. Physicochemical parameters of the water quality of selected boreholes at various distances were examined, and the results indicated that borehole A, B and C had Total Coliform Bacteria (TCB) of 140.0 cfu/100ml, 120.0 cfu/100ml and 0 cfu/100ml respectively. Total Heterotrophic Bacteria (THB) threshold of A, B and C indicated 6.0x103cfu/ml, 4.8x103cfu/ml and 42cfu/ml respectively. The water quality index (WQI) of boreholes A, B and C also indicated 560.82, 475 and 2.6, respectively. The result of borehole C water quality indicated it was excellent and potable for drinking. The WQI obtainable at A and B indicated polluted boreholes due to possible leachate infiltration into the groundwater and proximity of these boreholes to the dumpsite. The study recommended the adoption of solid waste re-use, recycling, and sanitary landfill waste management approach as best practice.
