Because on-site composting requires a solid waste permit and a composting permit, there are requirements similar to waste treatment for leaching of nitrates and other runoff. Clay-like soils are necessary to prevent runoff from entering the local watershed without being appropriately filtered. With the help of the Spring Creek GIS (Global Information System), we looked at land use and soils data to locate any possible composting sites. In addition to having the appropriate soil, a site must be available for use. (For example, it would not be an option for land that is in the prairie restoration site or underneath an academic building.) The soils on the Carleton College campus are predominantly fairly level loamy and silty soils. These soils are well drained to poorly drained and are found on uplands. Water can quickly filter through sandy and loamy soils, which make them inappropriate for composting. Although it is still possible to compost on land that does not have an appropriate soil structure, the costs would be significantly higher. To compost on-site, it would be necessary to purchase clay to line the composting area. Based on the soil data, there is not a site suitable for composting on campus.
