St. Louis Airport Storage Site (SLAPSS) environmental monitoring summary, calendar year 1984

The routine environmental monitoring program for SLAPSS and the off-site ditches includes surface water and sediment sampling of Coldwater Creek, groundwater sampling of six monitoring wells within the site boundary, radon gas monitoring, and external gamma radiation measurements. The various environmental sampling, monitoring, and analytical procedures are summarized. Environmental monitoring results listed in the individual tables are the arithmetic average of individual results. Individual sources of error (i.e., analytical error, sampling error, etc.) have not been estimated. In computing averages, where values are less than the limit of sensitivity of the analytical method, the average value is reported without the notation ''less than''. Because SLAPSS is not controlled or regulated by DOE or NRC, no specific guidelines for radionuclides are applicable to the site. For comparative purposes, guidelines or limits from both DOE and NRC are provided as footnotes in the various tables. In addition, as the various monitoring results are reported, DOE Concentration Guidelines (CGs) are provided to show how the monitoring results would have compared had the site been owned by DOE. The CGs represent the concentration of a radionuclide in air of water that would limit the dose to the most highly exposed individual to equal to or less than accepted radiation protection standards. 6 refs., 1 fig., 4 tabs
