摘要：The current study is aimed at assessing the physico-chemical characteristics of groundwater quality along with seasonal variations near the Ghazipur landfill site, Delhi. The sampling points were selected within the radius of two km from landfill location. Samples of groundwater were collected during preandpost monsoon seasons and physico-chemical parameters were analyzed. The study exhibits that groundwater in the surrounding area of Ghazipur Landfill site has been contaminated by percolation of leachate. Most of the results have shown higher concentration of chemical contaminants in ground water samples in pre-monsoon as compared to post monsoon season which may be on account of dilution effect during monsoon season. Total Dissolved Solids (TDS), hardness and iron exceeded the maximum permissible limits in most of the locations. However, the alkalinity, fluoride and chloride contents were within the permissible limit but they were found much above the desirable limit. Interestingly, the concentration of nitrate was found below permissible limit and was well in the desirable limit except one location which is contrary to the earlier studies and requires further research. These results showed that there is deterioration in the ground water quality and hence the water is not suitable for drinking purpose. This situation needs urgent attention and immediate action to prevent the further contamination of groundwater.
