Abstract
The groundwater is contaminated greatly with acidity, alkalinity, noxiousness, heavy minerals, and microorganisms throughout the world due to population growth, urbanization and industrial development. Henceforth, evaluation of water quality of groundwater and surface water is extremely important to prepare for remedial measures. The slice of research was carried out to study the ground water as well as surface water quality, and physicochemical characteristics of Kodungaiyur Marsh Area, Chennai, India. The study area is situated between latitudes 13.135683, 80.265260. Various parameters like pH, Total Dissolved Solids, Chlorides, Sulphates, Total Alkalinity, Biochemical Oxygen Demand, Chemical Oxygen Demand,etc.. give a picture of quality parameter of the town. If the water quality exceeds the pollution level for groundwater which shows that the water is not safe for the use of various purposes like domestic, aquatic life, agricultural, industrial etc.
