Abstract
An assessment of the pollution level of groundwater in Gariki residential area, Enugu Urban, Nigeria has been carried out. Six study locations were involved in the study. The water samples collected from the study locations were subjected to physico-chemical and bacteriologic analysis in the laboratory. The PH meter, turbidmeter and conductivity meter are among the instrument utilized in the analysis of the physical parameters while the concentrations of heavy metals were detected by the use of a spectrophotometer. The approved UNEP (1996b) standard was the method employed in the bacteriological analysis of the water samples. High acidity level of 1.3 was obtained in the GM (Gariki Market) study location and this shows that it requires water treatment. The physico-chemical results fall within the WHO acceptable limit. However, water samples O.S. (Odudukoko Street), A.R (Akwuke Road) and A.B (Army Barracks) show the presence of E. coli and coliform. These study locations also require water treatment because of their bacteriological infections. Proffered measures include, legislative move for general groundwater protection, extension programme on groundwater protection, routine water sample analysis, regular evacuation of septic tanks, sitting of refuse landfills away from residential areas among others. These measures will foster good health which implies great productivity and sustainable development. Keywords: Pollution, groundwater, physico-chemical, bacteriological
