Water Quality Assessment of Groundwaters (Hand-Dug Wells) in Abeokuta North Local Government, Nigeria

Abstract

Groundwater is the major source of water for municipal use in the AbeokutaNorth Local Government of Nigeria. However, there is a tendency for its quality to deviate from recommended standards as most groundwater sources are close to regions prone to erosion and most well are not usually covered. The tragedy is that the adverse effect might creep into the ecosystem and affects humanity if a regular check on the quality is not been made. The Geographical location and altitude of each well location were taken using Global Positioning System (GPS). The moderate PH range (6.30-7.36) can be linked to low values of TDS (352 mg/L) and EC (695 ms/cm) which are within the standard recommended for drinking- indicate a low concentration of salt contents. The relationship between the parameters shows a direct trend with the hydraulic head. Hence, groundwater sources (wells) in Abeokuta North Local Government are good for drinking.
