Abstract

In recent days ground water quality is deteriorating at alarming rate due to increased industrial activities. This study assessed the water quality of 30 samples collected from 4 locations of Pydibhimavaram industrial area. An investigation was carried out by collecting a total of 30 ground water samples for three seasons in study area to assess the ground water quality for its suitability for agriculture and domestic purpose. This study focused on variation of water quality parameters with reference to water level fluctuations. The well reduced levels were determined with the help of total station and these levels are connected to the mean sea level. Ground water levels from the well top surface were measured using water level indicator. Water quality parameters such as pH, total hardness, chlorides (Cl), iron (Fe), electric conductivity (E.C), sulphates (SO₄ ^2-), nitrates (NO₃ ^-), cadmium (Cd), lead (Pb), nickel (Ni) and zinc (Zn) were analyzed. These parameters were estimated using standard procedures and the results were compared with environmental quality standards. The results indicated that the water quality of the study area exceed the permissible limits of standards. This showed that the ground water of the study area was contaminated due to the industrial effluents.
