Assessment of Water Quality of Peddacheruvu, Sambaiah Cheruvu, Gaddapotharam and Rudraram Cheruvu of Medak District

Abstract

In the present study, an attempt is made to analyze the physico-chemical aspects along with trace elements and organics of four different lake waters of the industrial area of Medak district namely - Gaddapotharam, Peddacheruvu, Sambaiah & Rudraram cheruvu. The lake water analysis shows that among all the lakes, Gaddapotharam Lake is the highly polluted lake followed by Rudraram Lake. Peddacheruvu and Sambaiah lakes might be polluted due to rainwater/storm water discharges. The results clearly show that majority of water quality parameters such as Chemical Oxygen Demand, chlorides and dissolved solids are quite high. This might be due to the collection of samples in summer during which the pollutants might have got concentrated and hence the analysis results are observed to be high. The levels of pollutants are found to be high at the inlet areas of the lakes close to industrial area. In addition, high levels in some sites are also due to agricultural and sewage drainages of some villages. Moreover, it is also observed that during midsummer all the lakes have dried up except for Gaddapotharam Lake. The dry sediments can be removed by digging out and replacing the bottom with good soil cover which will support aquatic life of the clean water that may enter with rainfall.
