Over exploitation and pollution of groundwater resources is considered to one of the major pollution problems these days. Even pollution of air, surface water or land may have a significant effect on pollution and contamination of ground water. Industries, human activities, agriculture, etc generate waste in various forms like solid, liquid and gas. If all this waste is not treated properly, it shall result polluting the environment and further affecting the quality of ground water due to its hydraulic connectivity with the hydrological cycle. In addition, leachate resulting from municipal or industrial solid waste dump site as well agricultural run-off also leads to ground water pollution. It has been estimated that around 45 million people globally are affected by water pollution resulting from excess iron, fluoride, arsenic, or sea water intrusion. The current study deals with physico-chemical analysis of ground water samples and suitability determination of water by using water quality index and Piper diagram for solid waste dump site near Pune. Water samples were collected from open wells as well as bore wells for pre-monsoon and post monsoon season and results were evaluated using residual sodium carbonate, sodium hazard, sodium adsorption ratio, and piper diagram. It can be inferred that, Ca-Cl type of water predominates the study area for both pre-monsoon as well as post-monsoon season.
