Abstract
The analytical data of various physico-chemical parameters indicates that some parameters like pH, Hardness, Calcium, Magnesium, Electrical Conductivity, DO, Chloride, Total Alkalinity, Iron are found to be excess than the prescribed limit in some groundwater samples of the study areas. The mean levels (mg L-1) of the metals ranged thus; 0.1 (Cd), 0.2 (Pb), 0.2 (As), 0.1 (Ni), 4.8 (Fe), 0.3 (Cr). The objective of this paper is to examine pollution threat, especially to the groundwater resources, around the places of town which is in the south and north of the City which suggest remedial measures that may also be relevant to other industrial area. The changes in the physico-chemical characteristics like temperature, transparency and chemical elements of water such as dissolved oxygen, nitrate and Calcium provide valuable information on the quality of the water, the source (s) of the variations and their impacts on the functions and biodiversity of the reservoir.
