Studies on physico-chemical characteristics of freshwater bodies in Khatav Tahsil, Maharashtra

The paper highlights the physico-chemical characteristics of eight freshwater bodies of Khatav Tahsil in Satara district of Maharashtra during winter and summer seasons. Investigations are based on different parameters, pH, EC, TDS, TSS, DO, BOD, COD, total alkalinity, total acidity, chlorides, free CO2, hardness, nitrates, phosphates, sulphates, etc. for which no earlier reports are available on these waterbodies. The study revealed significant changes in water quality during the two seasons. pH of water was alkaline; EC, hardness and alkalinity tend to increase during summer and decrease in winter. DO was maximum during winter, and minimum during summer. The seasonal variations of various factors were studied and interrelationships existing between them discussed.
