Abstract

Water is one of the basic components of the biotic environment and all living organism’s activities depend on it. For water to befit for the industrial and domestic usage, it needs to be handled with care to maintain its purity. The aim of this study is to qualitatively evaluate some physical, chemical and bacteriological parameters of water samples of rivers in Yobe State. Physiochemical parameters analyzed include; calcium, chloride, chromium, fluoride, iron, manganese, magnesium, nitrite, sulphate, and total hardness using atomic absorption spectrophotometer (AAS-DR2000), while Omega conductivity meter (CDH221) was used for the determination of total dissolved solid, conductivity and temperature. Turbidity was determined by absorptiometry method. Colour was determined by Platinum-cobalt (Pt-Co) method. PH was determined with litmus paper and compared on colour chart. The bacteriological assessment was conducted according to the membrane filtration method.  Results of sample water from Gashua showed turbidity of 375.66±57.82 FTU, Chloride 8.36±0.31 mg/L. Colour (Pt-Co) obtained for Gashua 421.33±14.85, Geidam 499.66±35.70, Katarko 429.66±17.61. Geidam Manganese 12.17±1.75 mg/L, Sulphate 72.33±2.05 mg/L. Damaturu Nitrate 33.2±2.25 mg/L. Bacteriological assessment showed Geidam and Katarko with 4.0CFU each respectively. These results could be attributed to the activities going on in this area with respect to the presence of large scale upland and irrigated farm land which may introduce leaching fertilizer into the river so also the presence of traditional potash mining sites. The results of the analysis of the five samples from various locations in Yobe State showed that the physical and chemical parameters of most of the water samples were within the acceptable limit of the WHO. While the bacteriological parameters determined exceeded the acceptable limits, suggesting that the water samples may be contaminated bacteriologically.
