Aspects of the Hydro-geochemistry of Groundwater in Agbor/Owa Communities of Delta State, Nigeria

The contents of barium, calcium, sodium, sulphate, phosphate, and cyanide in groundwater in Boji-Boji (BB) area and suburbs of Ika land, Delta state, Nigeria, were investigated. Without any form of treatment, groundwater is the primary source of water for the residents of these communities. The essence of this exercise is to study some aspects of the hydro-geochemistry of groundwater in these communities to establish its wholesomeness for consumption and the sustainable well-being of the people. There are 55 borehole water sites spread across these five sample sub-areas. Solar Unicam flame Atomic Absorption Spectrophotometer was used to analyse the metal ions. The colorimetric method was used to determine the sulphate, phosphate, and cyanide contents. The results show the presence of sodium, calcium, sulphate, and phosphate. However, barium and cyanide were below the detection limit. Second, the aquifer contained a higher proportion of calcium and sulphate than sodium and phosphate.Third, a mean ratio value of 0,018 and 0.158 were observed for Na+/Ca2+ and PO43-/SO42- respectively. Fourth, sodium had a strong correlation with all of the other parameters. Finally, the concentrations of the studied parameters are below the WHO's maximum contaminant levels, implying that the water is free of analytes. However, the sodium concentrations in many sample areas continue to cause concern from a health standpoint.
