was to determine the seasonal variations of groundwater, the influence of the rock
formations on the groundwater solute chemistry and groundwater domestic-agro-industrial
quality using hydrogeochemical tools and physicochemical parameters; Ionic
ratios, Gibbs diagrams, Piper diagrams, Durov diagrams and water quality
physicochemical parameters; in the rainy season, pH ranged from, 4.6-7.1; EC, 0.023-1.63 mS/cm;
Temperature, 26.3-290C andTDS,
0.015-1.09 mg/L and in the dry season pH ranged from 5-7.2; EC, 0.01-1.61 mS/cm;
Temperature, 24.4-29.50C andTDS,
0.01-1.08 mg/L. Forty groundwater samples; 20 per season, wet and dry
were analysed. Themajor ions fell below WHO acceptable
limits for both seasons. The sequences of abundance of major ions
were, Ca2 >K>Mg2 >NH4>Na,
HCO3->Cl->SO42->NO3->HPO42- in wet season and Ca2 >Mg2 >K >Na>NH4, HCO3->Cl->SO42->HPO42->NO3- in dry season. Ion-exchange,
simple dissolution and uncommon dissolution processes determined groundwater
character. Groundwater ionic content was as a result of ion
exchange from rock-weathering. Water types
are; MgCl and MgHCO3 in both seasons. Hydrogeochemical facies are; Ca-Mg-Cl-SO4,characteristic of groundwater some distance
along its flow pathand
of freshly recharged groundwater from precipitation. The groundwater indices of; Sodium Percent (%
Na), Residual Sodium Carbonate (RSC) , Kelley’s ratio (KR), Sodium Adsorption
Ratio (SAR), Electrical Conductivity (EC), Total Dissolved Solid (TDS),
USSL？ and Wilcox index were determined,
evaluated and found to be suitable for agro-industrial uses in all seasons. Permeability Index (PI) ,
Water quality index (WQI) and Magnesium Adsorption Ratio (MAR) were not
suitable in some areas and in some seasons.
