Abstract

Water contamination, particularly of surface water, is predominantly attributed to anthropogenic activities, notably the indiscriminate discharge of effluents (comprising both industrial and domestic wastes) into local drainage systems, which ultimately convey these pollutants into natural water bodies. This study aims to assess the physicochemical characteristics of wastewater sourced from a soap-manufacturing industry. Parameters such as pH, temperature, electrical conductivity, total solids (TS), and dissolved oxygen (DO) were analyzed using a Hanna multi-parameter probe (HI 9813-6 pH/EC/TDS/°C Meter). Additionally, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), oil/grease content, and heavy metal concentrations were determined in accordance with standard analytical procedures. Three effluent samples, collected from designated point-source discharges within the industrial facility, were examined. The zinc concentrations (15.13 mg/L (A), 12.21 mg/L (B), 5.88 mg/L (C) ) for the effluent samples were found to exceed the permissible limits established by the Federal Environmental Protection Agency (FEPA). Furthermore, Samples A and B exhibited critically elevated COD levels ( 97, 92) respectively, which are deemed highly non-compliant with FEPA guidelines. The findings of this study underscore the urgent necessity for the treatment of industrial effluents prior to their release into the environment.
