在2004-2007年期间，对印度西孟加拉Damodar河（北纬24 A度26（'）和东经86 A度53（'））点源的水质参数大肠菌群进行了评估。该场地接收来自煤矿和工业的采矿和工业废水。每月收集的水样显示存在大肠杆菌和链球菌，在整个研究期间，菌落形成单位在2，600至20，000个/100毫升之间，在后季风时期的9月至12月期间达到高峰。发现两种细菌的相对丰度为y（E.大肠杆菌）= 1.41x（链球菌）-8.07，呈正相关（r = + 0.868，df = 34）。主成分分析揭示了三个因素，以澄清所观察到的环境变量的方差。采样点河水理化参数的平均值始终高于世界卫生组织和其他监管机构规定的水平，符合污染水的标准。这些水样中大肠菌群的存在保证了适当的措施，以减少点源污染，并采取适当的补救策略，以防止来自该地点和下游的Damodar河的生活用水污染。
An assessment on the water quality parameters coliform including the bacterial abundance from a point source of river Damodar (24A degrees 26(') N and 86A degrees 53(') E), West Bengal, India was carried out during the period of 2004-2007. The site received mining and industrial effluents from the collieries and industries. The water samples collected on a monthly basis revealed the presence of the coliform bacteria Escherichia coli and Streptococcus sp., between 2,600 and 20,000 colony-forming unit/100 ml throughout the study period with peak abundance during the months of September to December, the post-monsoon period. The relative abundance of the two bacterial species was found to be y(E. coli) = 1.41x (Streptococcus) - 8.07 and were positively correlated (r = + 0.868, df = 34). Principal component analysis revealed three factors to clarify for the observed variance of the environmental variables. The mean values of the physicochemical parameters of the river water at the sampling sites were consistently higher than the levels specified by WHO and other regulatory bodies and qualify as polluted water. The presence of the coliform bacteria in these water samples warrants for proper measure to reduce the pollution at the point source and proper remediation strategies to combat contamination in the domestic water usage from river Damodar from this site and downstream.
