Abstract
Groundwater pollution around the improperly constructed landfill areas of the growing cities has always been in the rising trend and hence its effects on the environment warrant a thorough monitoring. The seasonal variations in the quality of groundwater from the dug wells surrounding the solid waste disposal site from the SE of Pune city (India) has been assessed by calculating the sodium adsorption ratio (SAR). The results indicate that the groundwater from the wells nearing the waste disposal site show consistent increase in the pollution from monsoon to summer through winter. The study further demonstrates that the wells near the site are severely polluted and the source is mainly the leachates emerging out of the decaying solid wastes. The recurrent addition of the solid waste in the dump site in the coming years would result in further exponential deterioration of the groundwater quality of the dug wells from the area and hence adequate steps are urgently needed to prevent further aggravation of the problem. Based upon the SAR values it is evident that most of the wells from the Hadapsar area have excellent groundwater for irrigation throughout the year; from Manjari area it is excellent to good; the Fursungi area has sub-equal proportions of excellent, good and fair groundwater, while in Mantarwadi, although most of the wells have excellent to good water, few wells have fair to poor quality water for irrigation purpose. In Uruli-Devachi about 50% wells have poor quality of water and hence can not be used for irrigation. Hence this study strongly suggests that most of the abstracted groundwater samples from the study area were suitable for irrigation except from Uruli Devachi area.

Keywords sodium adsorption ratio (SAR); groundwater pollution; solid waste disposal.
