Abstract
This contribution makes use of AquaChem computational platform to determine the mineral assemblage and mineral speciation of hand-dug well water of Kakamega Metropolis. Mineral speciation, hydrochemical behavior, charge balance error (CBE), and piper plots are important factors in establishing mineral composition and water histories of a given hydrological regime. The ionic strength as predicted using AquaChem was between 0.0051 and 0.0068 in the hand-dug wells investigated in this study. AquaChem gave a charge balance error (CBE) of between 38.0 and - 0.9, and predicted that Kakamega waters belong to the class of primary waters having very low concentration of total dissolved solids (TDS<150 mg/kg). Piper plots indicated that the water is possibly from local supply of each element throughout history, origin, and migration of the water. Evidently, the oxygen-rich ions represented by HCO3- and SO42- were abundant compared to Cl- and F-. This implies that the water originates from shallow aquifers, and is of low salinity.
