Description

The present study was designed to investigate the changes of physico-chemical parameters in Vettar estuary, Nagapattinam District, Tamil Nadu, India for the period of 6 months from January to June 2014. Water samples were collected from upper reaches (Station-I, River) and lower reaches (Station-II, Estuary) from Vettar for period of 6 months from January to June 2014. Various physico-chemical parameters of the water in were determined. In the present study, it has been observed that high temperature was noticed in the months of April to June at station-I and station- II in the Vettar estuary. Temperature, pH, dissolved oxygen, salinity, total dissolved solids, phosphorous, nitrite, ammonia and fluoride were varied in both stations in different months. In the present study revealed that all the physico-chemical parameters were more in the upper reaches than in the lower reaches, which may be due to the industrial effluents mixing up with estuary. Suitable remedial measures should be taken to prevent the mixing of domestic sewage and discharge of effluent into the river to maintain the quality of Vettar estuary.
