Impact of a Piedmont Sanitary Landfill on Surface and Ground Water Quality

摘要

The primary objective was to evaluate the chemical quality of ground and surfacewater at a sanitary landfill located in the Piedmont region of North Carolina. The landfill is 'typical' in many respects of municipal waste disposal facilities in the region. The facility was constructed without an engineered liner or leachate control system. Ground water immediately down gradient from the refuse disposal areas is contaminated with a wide variety of pollutants. At the downgradient boundary of the landfill, pollutant concentrations are much lower although ground water released from the landfill may violate N.C. ground water quality standards for iron, manganese and pH. Synthetic Organic Chemicals (SOC's) may also be present in concentrations exceeding ground water standards. The overall chemical quality of stormwater runoff released from the Piedmont Landfill is comparable to runoff from other urban watersheds which do not receive landfill runoff.
