Organic priority pollutants in wetland-treated leachates at a landfill in central Florida

The occurrence of organic priority pollutants originating from leachate at a landfill adjacent to wetlands in Orange County, Florida was studied and compared to a prior one-year study. Volatile organic compounds were detected in groundwater at total concentrations of less than 150 μg/L. Few base/neutral and acid extractable compounds were detected in surface water and groundwater. Both studies suggested that organic priority pollutants present in the solid waste were likely metabolized by microorganisms or degraded, sorbed on particulate matter, or diluted to non-detectable levels.
