Water samples were collected from 14 open wells, 34 bore wells and two reservoirs to study the ground water quality of Greater Visakhapatnam city. The samples were analyzed for the parameters like Temperature, pH, Conductivity, Total dissolved solids, Dissolved Oxygen, Hardness, Calcium, Magnesium, Nitrate, Sodium, Potassium, Chloride and Alkalinity. Low ionic concentrations in ground waters far (7–14 km distance) from the sea coast were observed which are within the permissible limits of WHO and ISI standards. Ground waters close to the sea coast i.e. one to two kilometers distance (60 to 150 feet depth) have high values of Conductivity, Total dissolved solids, Hardness, Chloride, Calcium, Magnesium, Sodium and Potassium which are not in permissible limits.
