ABSTRACT

Physicochemical and Bacteriological analysis were carried out on water and air samples from selected locations within Garki Area 1 police barracks Abuja, Nigeria. A total of 50 samples of water and air were collected from five different locations (Block 13C, Block 14A, Block Block 3C, Block 15C, and Block 12C) and analyzed using standard methods. The physicochemical parameters monitored included pH, temperature, electric conductivity, turbidity, dissolved oxygen, appearance, odour, taste, hardness, chemical oxygen demand, biological oxygen demand. Preliminary, cultural, morphological, biochemical characteristics of the isolates revealed the following isolates; Escherichia coli, Klebsiella sp, Pseudomonas sp,Salmonella sp, and Bacillus sp. The total Coliform Count from the water of these blocks ranged between 2.5-3.8´108cfu/ml, while the total Coliform Count of the air. Samples of these blocks ranged between 1.9 3.1´108cfu/m3. Isolated bacteria of water with percentage of occurrence were Klebsiella sp. (80%), Salmonella sp (56%), Enterobacter sp (48%), Escherichia coli (48%) and Pseudomonas aeruginosa (44%). While the isolated bacteria of air with percentage of occurrence were Pseudomonas aeruginosa (60%), Klebsiella sp (52%), Bacillus sp (52%) and Escherichia coli (44%). Findings from this study indicates the presence of pathogenic bacteria with health risk to human in both water and air environment. Therefore there is need for improved sanitation hygiene and water quality as well and regular hygiene education in the study area.
