Areas which would not support a landfill were eliminated. Remaining sites were rated as having slight, moderate, or severe restrictions for use as an area method sanitary landfill based on the Natural Resource Conservation Service (NRCS) Sanitary Facility Report, and the NRCS Soil Interpretations Rating Guide.
