Description:
There are tens of thousands of closed landfills in the United States, many of whicih are unlined and sited on alluvial deposits. Landfills are of concern because leachate contains a variety of pollutants that can contaminate ground and surface water. Data from chemical analysis of ground water collected downgradient of a closed municipal landfill, the Norman Landfill, Norman, Oklahoma, was used as the basis for this study. Provious reports suggested the presence of high concentrations of napthalene in ground water at this site. Napthalene is a semi-volatile, polycyclic aromatic hydrocarbon with numberous adverse human health effects. In addition to napthalene, high concentrations (as much as 233 mg/L) of ammonia (NH4+) were also detected insome wells. Although the chemical compositon of leachate is highly variable, ammonia is always present and concentrations as higih as 1800 ppm have been reported.
Studies are ongoing to determine the effect of leachate geochemistry, including high organic carbon content on oxidation kinetics. This study suggestes that clinoptilolite zeolite and KMn04 may be useful for in situ remediation of groundwater contaminated with leadfill leachate.
