Abstract: Landfill is a major municipal trash treatment measure but the adverse impact on the adjacent environment is increasingly obvious. This paper presents the study of Jinkou landfill on the adjacent environment. The chemical components and other indices of the landfill leachate on the adjacent groundwater and soil were investigated. Throughout the monitoring results of soil and groundwater, it is concluded that the perched water at the upper and middle layer was moderately contaminated and soil and ambient atmosphere were relatively unaffected. The landfill leached liquid with heavily contaminated is a major impact to the adjacent environment and it should be properly treated for the environmental improvement. 

Key words: landfill, landfill leachate, groundwater, atmosphere, soil, pollution
