Abstract
Abstract This study was carried out to assess the suitability of groundwater for drinking and irrigation purposes by interpreting the hydrochemical species of groundwater samples. Six water samples were collected and assess to determine the concentration of some ions, pollution load index (PLI), contamination factor (CF), water quality index (WQI), sodium adsorption ratio (SAR), magnesium hazard (MH), Kelly ratio (KR) and percentage sodium (%Na). The result revealed that most of the ions have concentrations within the WHO permissible limit for drinking water except biological oxygen demand (BOD), chemical oxygen demand (COD) and , which exceeded the WHO standard in some samples. The mean abundance of the cations is , while that of the anions is . The result reveals that and are the most abundant cation and anion respectively. CF reveals a low concentration (<1) of , , , , and high concentration (>1) of . The values of PLI were very low indicating no pollution. The WQI reveals the samples with excellent (<50) rating, while those above 100 (>100) were rated as poor. The SAR, MH, KR and %Na reveal the groundwater status for irrigation based on the ratings of the indices.
