Laboratory studies on water quality assessment of groundwater of open dug wells and surface water of Lake Waddepally in Warangal city, India

The water from lakes and reservoirs are collected, treated and supplied for public distribution by Govern- ment agencies in India. Water from open dug wells (Groundwater) is one of the major resources for individual residents. Studies on physicochemical parameters of groundwater of open dug wells and surface water of Waddepally Lake in Wa- rangal district of Andhra Pradesh State are carried out and the results are presented in this paper. The groundwater samples were collected from 15 open dug wells in an area of 4 km from the lake. The lake water samples from 4 different locations were taken from top surface, 1m and 2m depth wise. Laboratory tests were conducted for determining (i) physical parameters: Temperature, pH and Electrical Conductivity, (ii) chemical parameters: Total Alkalinity, Dissolved Oxygen, Total Hardness, Chlorides, Fluorides, Total Solids, Calcium (Ca 2+ ), Magnesium (Mg 2+ ), Carbonate (CO3 - ), Bicarbonate (HCO3 - ), and Chemical oxygen demand.
