Study of Physico-Chemical Parameters of a Freshwater Lake in Sadasivpet, Sangareddy Dist., Telangana State

Abstract

The present study is about investigation of physico- chemical parameters and to find out different  algal forms in water samples of Sadasivpet lake. This lake is located in Sadasivpet, Sangareddy district, Telangana state. .  Study was carried out for two years from January 2018 to December 2019. Water samples were collected from three sampling stations of lake and were analyzed  in the laboratory.  Physico-chemical  parameters such as Colour, Odour, Temperature,  pH, TDS, Turbidity, Carbonates, Bicarbonates, Ca hardness, Mg hardness, Total  hardness, Chlorides, Nitrates, Sulphates, Silicates, Phosphates, BOD, COD, DO etc., of lake  were estimated Analysis was carried out by using the standard methods. During the study period algal forms were observed in the water samples.  The identified algal forms belonged to various groups  were observed throughout the study period. Abundant growth  of green and diatoms was observed during winter season.   Cyanophycean members were abundant during summer season. Euglenophyceae members were observed throughout the study period Some  algal blooms were identified in this study. During the present study. Lake water showed early eutrophication state with pollution due to  dumping of sewage and other waste directly into lake.  The condition is alarming therefore urgent action is required for the lake existence.
