CHARACTERISTICS OF FLORIDA FILL MATERIALS AND SOILS 1990
Roessler, C., R. Morato, D. Smith, AND J. Wherett. CHARACTERISTICS OF FLORIDA FILL MATERIALS AND SOILS 1990. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/R-94/052 (NTIS 94-176906), 1994.
The report gives results of laboratory work by the University of Florida in support of the Foundation Fill Data Base project of the Foundation Fill Materials Specifications Task Area of the Florida Radon Research Program (FRRP). Work included determination of radon concentrations in soil gas samples and physical and radiological characterization of soil/fill samples to provide data for further use in modeling radon production, transport, and entry. This work adds to the 35-site, 54-sample data base developed in an earlier study by the University of Florida under the State University System Board of Regents Radon Research Program. The earlier study emphasized materials being used as fill at construction sites; only one-third of the samples were native surficial soil at construction or existing house sites. The study reported here emphasizes sites as prepared for construction. Twenty-three sites were samples. Two sites were selected in each of 11 regions designated to represent population centers covering the range of geographic, topographic, and geological features in Florida. Also included was a Brooksville school construction site being studied in another FRRP project.
