Hydrogeochemical Characterization of Groundwater of Field Y, Offshore Niger Delta

Hydrogeochemical analyses were carried out on groundwater samples in order to understand the hydrochemistry of the water. The results revealed that groundwater has a high electrical conductivity, which could be as a result of more chemicals dissolved in the water and total hardness observed in all samples shows that the water isn’t hard water. Major cations and anions were identified using Piper Trilinear diagram Durov diagrams and Stiff diagrams. The parameters studied include; Ph, Electrical conductivity, Temperature, Total Suspended Solid, Salinity as Chloride, Sulphate, Total Hardness, Total Hydrocarbon Content, Nitrate, Phosphate, Alkalinity, Calcium, Sodium, Magnesium, Potassium, Iron, Zinc. The major cations are: Sodium (Na+), Potassium(K+), Calcium (Ca2+), while the major anions are: Bicarbonate (HCO3–), Carbonate(C03–), Sulfate (SO4–), and Chloride (Cl–). TDS is the major physical parameter that is dominant in the Durov diagram, although the analysis in the Durov, Piper and Stiff diagram shows that Ca2+ and HCO3–, are the major cation and anion respectively which implies that the groundwater in the study area are Ca2+ and HCO3–. It was also observed that the quality of groundwater was suitable for domestic purpose and agricultural purpose.
