PHYSICO – CHEMICAL PROFILE OF KANGSABATI RESERVOIR, WEST BENGAL, INDIA

The recent investigation deals with the assessment of water quality of Kangsabati reservoir during the study period March, 2010 – February, 2012. Statistical analyses have been carried out by calculating correlation coefficients among several parameters. The observed values of various physico-chemical parameters of water samples were tallied with desirable, permissible, acceptable range – recommended by WHO, FAO, BIS, NRAC, SRAC, ICAR guideline whichever is properly applicable for the purpose of irrigation, pisciculture and drinking. It is found that strong positive correlation builds a network among air and water temperature; dissolved oxygen and transparency; hardness with Calcium, Magnesium and phosphate; salinity and chloride; photic depth and transparency; free CO2 and conductivity. A highly negative correlation was found among water temperature with dissolved oxygen and phosphate; total inorganic nitrogen and PH; photic depth with phosphate and hardness; phosphate and transparency. All the physico-chemical parameters of Kangsabati Reservoir are within the acceptable limit set by above mentioned organizations except conductivity value which recorded to be low .
