Evaluation of Physico-Chemical Parameters to Assess Hussain Sagar and Saroor Nagar Lake Water Quality in Hyderabad, Telangana, India

Abstract

Lakes are vital resources, natural surface water course also play a crucial role in groundwater recharge and they regulate the urban climate nowadays. Sewage discharge, improper agricultural practices and urban run offs have disrupted the ecosystem .In Hyderabad there are 185 lakes in that only 10 lakes have good water quality current situation due to domestic sewage and industrial waste water discharge are mixed with lake water. For our study we have selected 2 lakes, Hussain sagar, and Saroor nagar from those 175 lakes. This paper examines the present lake water quality, Four sample stations were located around two lakes totally24 samples were collected as per standard methods and, samples have been analyzed for Physico-Chemical parameters such as pH, TH, TDS, Ca2+, Mg2+,Cl-, HCO3, CO3, DO,BOD,COD. Results obtained were compared with water quality standards, irrigation standards and compared with previous study to analyzed that parameters limits.pH is observed for Hussain sagar lake are fall within the acceptable limit, for Sarooro nagar is observed are increased.TH, TDS, Ca2+, Mg2+,Cl-, HCO3, CO3 were exceeds the acceptable limits , DO,BOD and COD for 2 lakes are within the acceptable limits at present because of covid19 lockdown last year all festivals were banned.
