ABSTRACT :

Coastal water quality is rapidly deteriorating due to the adverse influences of domestic, industrial and commercial activities. Microbiological water quality monitoring is primarily based on monitoring for indicator organisms, whose occurrence ascertains the presence of pathogens. The data collected, during 2002-2010, from identified hotspot locations along the Indian coasts during pre-monsoon (February to May), monsoon (June to September) and post-monsoon (October to January) was analysed mainly for evaluating the variations in the abundance. Notably their abundance was far above the permissible limits set by either CPCB or USEPA at many locations. This high abundance can be attributed to land run-offs as well as anthropogenic activities along the coast. Besides examining the data sets for their relatedness to certain physico-chemical parameters, an attempt is also made to report the possible ecological consequences of the preponderance of sewage pollution indicator bacteria in terms of their health effects on resident flora and fauna as well as coastal space utilising activities (tourism, fishing, shipping etc). Periodic microbiological analyses of coastal ecosystems helps create awareness of the quality of water body and evolving suitably measures that can be adopted to avoid threats from sewage pollution indicator bacteria to marine and human life.
