Site Suitability Analysis for an Intermountain Solid Waste Facility: A Study for Cache County, Utah

The goal of this project was to analyze Cache County for potential sanitary landfill sites covering the period 2020 to 2120. The county population and per capita solid waste were estimated. The minimum landfill size was then calculated. A geographic information system (GIS) was used for data storage and vii analysis. Relevant data were gathered. 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. Seventeen sites were designated as sites for further evaluation. A landfill ranking system giving a primary and/or secondary rating to data items was developed. Nine prime sites had one secondary (.,a ting. These sites should be more closely investigated to determine which are the best potential sites. (136 pages
