Study of Physico-chemical parameters of Mominpet Lake in Vikarabad Dist., Telangana State., India

Abstract

The present study is about analysis of Physico-chemical parameters and to know about different  algal forms   of Mominpet lake. This lake is located in Mominpet village of Vikarabad District of  Telangana state. The parameters such as Temperature, pH, TDS, Turbidity, Total Hardness, Calcium Hardness, Magnesium Hardness,  Nitrates, Silicates, Sulphates, Phosphates, Chlorides, BOD, COD, DO etc., of lake water  were estimated.  Study was carried out for two years from January 2018 to December 2019. Water samples were collected from selected  three sampling stations of lake and were tested  in the laboratory. study was carried out by using the standard methods prescribed by APHA. The algal forms were identified by using various keys.  Chlorophyceae, Cyanophyceae, Bacillariophyceae, Euglenophyceae members  were observed throughout the study period. Seasonal variations were observed in  the presence and density of various algae. Lake water analysis revealed that  density of diatoms are high in spring season and winter season. The presence of some algae in high density indicates that the Lake water was unpolluted and good to support life.

The results indicate that most of the parameters were within the limit given by WHO, but only few parameters are not in the range. Physico chemical parameters analysis of the lake water showed seasonal variations  throughout the study period. During the present study, lake water showed high BOD,COD and low DO values. This condition  may be due to anthropogenic activities like washing clothes, cleaning animals and dumping of sewage directly into lake.
