Physicochemical Assessment of Groundwater Quality in Akure, Southwestern Nigeria

This paper investigates the physicochemical properties of 36 hand-dug wells in the North-western part of Akure, Nigeria. 36 hand-dug wells were analysed for some physicochemical parameters such as temperature, pH, electrical conductivity, redox potential (Eh), total dissolved solids, Ca, Mg, Na, K, HCO3, Cl, SO4, total alkalinity, total hardness and acidity. Results showed that all the wells except for wells 8 and 31 have their physicochemical parameters within the WHO guideline value. The high level of these physicochemical parameters in wells 8 and 31 could be attributed to geologic formation of these areas. Since most of the occupants of the area depend on these well water supplies for drinking and other domestic needs, it is recommended that any source of contamination should a minimum of thirty five meters away from any source of contamination.
