Groundwater is the principal source of water in this area. Agricultural practices within the basin are widespread and located close to groundwater wells. The study aims at evaluating the groundwater vulnerability to contamination in the vicinity of a Municipal solid waste landfill site, Dubagga, Lucknow, India, using DRASTIC model integrated with GIS tool has been used to evaluate the groundwater vulnerability of this area. The generated vulnerability map was then validated using physic- chemical and heavy metals analysis of samples collected from the dumping site's nearby wells to determine the area that poses the greatest danger of pollution. According to the vulnerability map, the study area was divided into three vulnerability classes ranging between a minimum value of 110 and a maximum value of 170. The vulnerability map revealed in the Lucknow, Dubagga, Municipal solid waste landfill site was very highly vulnerable to groundwater contamination. The resulting vulnerability map was then validated using a physico- chemical and Heavy metals analysis of samples collected from nearby wells of the dumping Site to assess the area which is of more potential risk to pollution. From the results of the study, Due to the all above parameters data, it is obvious from the foregoing data that the quality of groundwater around the Municipal open dumping site is deteriorating. It is clear that the concentrations of Mg2+, F- and Cr6+ exceeds their respective permissible limit in groundwater samples. Quality of groundwater is unfit of drinking in GW5 and GW6 sample and very poor in GW3 and GW8 sample and poor in GW1, GW2, GW4, GW7 and GW9 sample due to the high and low concentrations of all parameters. Then the DRASTIC model validation with water quality parameters is applicable and both results shows the same sampling locations with very high concentration, high concentration and moderate concentration.
