Physico-chemical properties of coastal water at Bakkhali, Bay of Bengal: Environmental assessment of coastal water

This work study is totally based on Spatial variations of some physicochemical properties (DO, BOD, COD, pH, temperature, TSS, Microbiological studies, Salinity etc. ) of the coastal waters of a segment of Bay of Bengal i.e. Bakkhali. Bakkhali beach situated in South 24 Parganas district of West Bengal, India. It is located on one of the many deltaic islands spread across southern Bengal.All the coastal water qualities parameters of Bakkhali (Bay of Bengal) were studied between the months of November 2009 and February 2010 before 12:00 a.m. The studies were carried out at three coastal sites of Bakkhali Beach (south extreme point, middle point and far north point, about 1.2 km along the shore) which is influenced by anthropogenic input from land-based sources. The site receives domestic, agricultural and industrial wastes. The water is being used for fishing, transportation of goods and people. The banks of the estuarine channels have traditionally been preferred locations for human settlement. Considering the various uses of this coastal segment, between Bakkhali to Haldia, constant monitoring of water quality is very important.
