Abstract

The study examined the physico-chemical parameters of Nigeria Institute of Leather and Science Technology underground water. The study analyzed ground water samples from four different collection points, Hostel borehole, Tannery bore hole, Mosque well and Staff quarters well using Atomic Absorption Spectrophotometer (AAS). Total dissolved solid value at the hostel was found to be 1231 mg/l, while the Tannery was 703 mg/l, the mosque was 448 mg/l and the staff was 428 mg/l. Chemical Oxygen Demand, Total hardness and some heavy metals were measured to be above the permissible standard of the World Health Organization after the analysis at the National Research Institute for Chemical Technology (NARICT) and Ahmadu Bello University (ABU). Solution proffered includes, treatment of tannery wastes before being discharged into the environment because it constitutes the major industrial activity in the institute. Furthermore, the students’ hostel in the institute should be provided with waste bins for dumping of waste.
