The Torbali River Basin is an important part of theKucuk Menderes Basin in western Turkey, containing a highlyproductive alluvium aquifer. Hazardous waste from urbanizationand industrialization has been stored above the main unconfinedaluvial aquifer for the last five years. This study is intended toassess the groundwater pollution mechanism from the hazardouslandfill site that is located above the surficial aquifer. Two mainvulnerable zones of the aquifer were determined using a GOD vul-nerability model. The hazardous solid waste was dumped on amoderately vulnerable zone without any precautionary measure.Leachate seepage from the landfill is a main contaminant for Na-Cl water types with electrical conductivity (EC) values of 4,275 to4,575 S/cm. The pH values of the leachate are between 6.3 and6.6. Concentration of As, Al, Fe, Mn, Ni, Sb, Se and Cd in the leachatewater standards. As a result, the waste leachate has a high contami-nant content that is causing groundwater pollution in a highly pro-ductive vulnerable zone. In this case, this vulnerable zone is notsuitable for waste disposal activities, and some improvement stud-ies should be done immediately to protect the main aquifer fromthe hazardous landfill site.
