Assessment of Physico-Chemical properties and sewage pollution indicator bacteria in surface water of River Gomti in Uttar Pradesh

This study was aimed to estimate current status of Physico-chemical chararacterstics and level of sewage pollution indicator bacteria and their variation at whole stretch of river Gomti. The sampling covered from upstream to downstream regions of the river representing pre monsoon (Jan-April), monsoon (May-Aug), and post monsoon (Sept-Dec) in two years i.e. 2008 and 2009. Eight water samples are subjected to Physico-chemical analysis like Water temperature, Total Solids, Total Dissolved Solids, Total Suspended Solid, Conductivity, pH, COD, BOD and DO. The bacteriological study of these samples included bacteriological parameters like Total Coli (TC), Faecal Coli (FC) and Faecal Streptocoli (FS) has given the information regarding the suitability of the water for various uses like drinking and other domestic applications. The results are based on Spatial Variation, Seasonal Variation and Temporal Variation. Conclusions revealed that large number of drains in Lucknow city and industrial discharge is mainly responsible for pollution in river Gomti.
