Abstract
Although, groundwater constitutes a major source of water supply especially in developing countries, however wastes generated arising from industrial growth and further complication caused by its indiscriminate disposal have been a major risk to groundwater vulnerability. Hence in this study,preliminary impact assessment of wastewater discharged from paint industry on proximal groundwater regime was carried out. Representative groundwater and effluent samples were collected from locations within the study area, and analyzed in accordance to the American Public Health Association standard methods. The values of the measured concentration of the parameters were compared with regulatory standards for drinking water. The concentrations of Mn2+, total Fe, Ca2+, TDS, TSS, total hardness and SO42- were mostly higher than the permissible regulatory standards. Total alkalinity values were very low in all the groundwater samples, while the presence of E-coli across all the sampling points indicated widespread pathogenic contamination. The results showed average lead concentration of 1.18 mg/l compared to the permissible level of 0.01 mg/l. Corresponding higher values of the physico chemical and biological parameters were observed in the discharged effluent samples. The observed high lead concentration have potential toxic consequences, and hence enforcement of localized waste minimization is recommended in order to promote waste recycling, and ensure adequate protection of public health and the environment.
