ASSESSMENT OF PHYSICO-CHEMICAL CHARACTERSTICS AND POLLUTION STATUS OF TAPI ESTUARY AT DUMAS JETTY, SURAT

Abstract

The rapid industrialization and anthropogenic activities along the estuarine system and the coastal areas have brought considerable decline in the water quality of the estuaries. Uncontrolled discharges of domestic wastes and industrial effluents have affected the Tapi estuary. Present study was carried out from June 2011 to May 2012 to determine the important physic-chemical parameters of water of Tapi estuary at Dumas jetty. Turbidity, conductivity, total solid, total dissolved solid, salinity, pH, dissolved oxygen, BOD, COD, calcium, chloride, sodium , potassium and nutrients like nitrate, nitrite and phosphate were studied. Correlation coefficient was carried out between various physic-chemical parameters. Significant correlation was found for salinity, TS, TDS, sodium and chloride .High BOD and COD was recorded exhibiting positive correlation. Kruskal wallis test showed that physic-chemical parameters varied seasonally. The study showed that the water quality of Tapi estuary at Dumas jetty was affected by industrial as well as anthropogenic activities.
