Quality Assessment of Afrotan Tannery Drinking Water Wells

Abstract

Afrotan tannery was established in 1983, in Albageer Industrial Area- Algazeera State - Sudan. It tans about 20000 skins per day. It uses different harmful amounts of chemicals in tanning processes and it discharges these harmful effluents in land near three drinking water wells. The objective of this study is to assess the quality of these wells and to investigate the contamination of the tannery effluents in the drinking water. Three liters of the tannery tap water was collected from a water reservoir which is fed by the above three wells. 24 parameters of Sudanese Standard Specifications for drinking waters and all the tannery effluents which are expected to contaminate the drinking water wells were measured. The results showed that there is no contamination of tannery effluents to the tannery drinking water wells, and all measured parameters were within the permissible levels of Sudanese Standard Specifications for drinking water. The study recommended periodic conduction of such studies in the future and to take the samples directly from each well to investigate any contamination.
