This study evaluates two existing dumpsites, namely Saggian and Mahmood Booti, regarding their inappropriate locations and related hazards. Four parameters were considered for the assessment: 1) threat to residential areas, 2) surface water bodies, 3) road network and related data, and 4) fluvial sediment sequence to groundwater depth. Geographic information system (GIS) has been used to conduct the study. Both dumping sites are unsafe for the neighboring community as 6,731 and 9,490 houses were found to lie within the hazardous region (1000 m) around Saggian and Mahmood Booti sites, respectively. Among them, 6.4% houses around Saggian dump are within 210 m of the site, while around Mahmood Booti dump the residential area starts after 210 m. It was calculated that 249.5 m³/day and 519 m³/day leachate is being produced by Saggian and Mahmood Booti, respectively. Saggian dumpsite is found to be more dangerous with higher co-efficient of permeability (11.37×10^-5 m/s), high water table (18.2 m below surface), and its location along the bank of the Ravi River. However, a higher number of accidents is found near Mahmood Booti, which may be an effect of the obnoxious smell from the dumped waste.
