ABSTRACT: Geochemical
assessment of groundwater samples from hand-dug wells within the vicinity of
Aba-Eku dumpsite was carried out for domestic and irrigation purposes. Ten
groundwater samples were collected both in dry season and wet season for
analysis of physico-chemical parameters: pH, EC, TDS,The results of the
analyses showed the groundwater samples to be within limits of WHO/NSDWQ.
However, higher values of concentrations of the chemical constituents were
noticed in well 5 nearer to the landfill. Interpretation of Piper diagram
showed CaHCO3 to be dominant in the area. Alkaline earth metals and weak acids are dominant cations and anions over the
alkalis and strong acids in both sessions. Groundwater in the study area is of
hard, fresh and alkaline nature. Assessment for irrigation purpose showed that
most of the water samples were suitable for irrigation purpose except in a few
locations.
