Assessment of Groundwater quality in Abeokuta North, Nigeria

In Nigeria's Abeokuta North Local Government, groundwater is the primary source of water for municipal usage. However, because most groundwater sources are near areas prone to erosion and most wells are not protected, its quality tends to differ from recommended standards. For the first time, we carried-out quality assessment of ground water in the bespoke region. The wells' geographical location and altitude were determined using the Global Positioning System (GPS). A pin was used to indicate the sagging of the water drawer's rope, which was then utilized to locate the position. The experiment was carried out at all the thirty-six locations present in the region. The moderate pH range (6.30-7.36) can be linked to low values of total dissolved solid TDS (352 mg/L) and electrical conductivity EC (695 µs/cm). A linear plot between EC and TDS, as well as a clustered column chart comparing EC and PH, reveal a clear association between parameters at p<0.01 (2-tailed T-test; microsoftExcel). The overall water quality index (WQI) of the parameters is 17.20 %, which is excellent by the standard of world health organization (W.H.O).
