Assessment of Physico-Chemical and Microbial Analyses of Hand Dug Wells in Makeni Town, Sierra Leone
Abstract: The various water samples were analysed for residual chlorine, ammonia, fluoride, nitrate, sulphite, lead, arsenic, chromium, and bicarbonate levels from January to August 2024. The bacteria contamination was investigated to determine the safety of the water for the consumption of human. The temperatures across the four wells ranged 27.3oC to 30.0oC, with and average values ranging from 27.94oC to 29.15oC. pH values were within the WHO recommended guidelines range of …

A Comparative Study of Inorganic and Natural Coagulants for Dairy Wastewater Treatment using Alum Sulphate and Moringa Oleifera
Abstract: The treatment of dairy wastewater is essential to reduce its environmental impact, particularly in terms of organic load and suspended solids. This study investigates the application of alum sulphate as an inorganic coagulant for dairy wastewater treatment and compares its effectiveness with the natural coagulant Moringa oleifera. The performance of both coagulants was evaluated based on key water quality parameters, including pH, Biochemical Oxygen Demand (BOD), Total Suspended Solids (TSS), …

Investigation of Pollution Status in River No. 2, Freetown, Sierra Leone, Using Physicochemical and Bacterial Indicators
Abstract: This study assessed the physicochemical and bacteriological quality of surface water in the River No. 2 watershed, Sierra Leone, through monthly sampling from March–August 2024 at upstream, midstream, and downstream sites. Analyses included temperature, turbidity, pH, electrical conductivity, total dissolved solids, ammonia, fluoride, sulfite, nitrate, lead, arsenic, chromium, and microbial indicators (Escherichia coli, fecal and non-fecal coliforms). Most physicochemical parameters met WHO drinking-water guidelines. pH (7.0–7.3), TDS (7–17 mg/L), turbidity …
