Hydrochemical and Electrical Resistivity Assessment of a Refuse Dumpsite within Olorunda Community, Ado-Ekiti, Southwestern Nigeria

— Sequel to various reports of incessant complaint of water pollution around the refuse dumpsite, this research work was conducted with the aim of proffering a timely solution to the problems before it escalated to epidemic. Surface DC resistivity and hydro chemical techniques were used to identify the various lithological layers, delineate groundwater contaminant plumes and assess the risk level of groundwater pollution within the study area. Eight vertical electrical sounding (VES) were conducted and the data obtained were interpreted quantitatively by partial curve matching and electronically iterated using WINRESIST computer iteration program. The apparent resistivity ranges from 108.3 - 4844.4Ωm, VES 7 has the lowest value of 108.3Ωm while VES 3 has the highest apparent resistivity value of 4844.4Ωm. The result of the hydro chemical analyses of the water from the study area was compared with the World Health Organizat
