Estimation of Water Quality and Physico-chemical Parameters of a Freshwater Lake

Abstract

The present study was undertaken to know the variation in different seasons in response to physico chemical properties of Laknavaram fresh water lake reservoir situated at Laknavaram village in  Mulugu district Warangal. The study was carried out over a period of one year. In India there are enormous number of natural and manmade water bodies used for various purposes, mainly for drinking and agriculture. One of the most severe problems in arid and semi-arid regions is high concentration of salts in soils and water resources. Thus, water quality and its management have received much attention in developing countries. The present study is aimed at assessing the Water Quality Index of reservoir water and assesses the impact of industries and human activities. Physicochemical parameters were monitored for the calculation of Water Quality Index for the monsoon, winter and summer seasons. Seasonal changes in physico- chemical parameters such as water temperature, pH, turbidity, transparency, total dissolved solids, total hardness, chlorides, phosphate, nitrates, dissolved oxygen and biological oxygen demand were analyzed for a period of one year from September 2021 to August 2022. The results indicated that physico-chemical parameters of the water were within the permissible limits.The results indicate that the lake water is Non-polluted and can be used for Domestic, Irrigation and Pisciculture.
