A demonstration of technologies for measuring trace elements in soil and sediments is being conducted under the U.S. Environmental Protection Agency Superfund Innovative Technology Evaluation Program. The field demonstration will be occurring from January 24 to 28, 2005, at the Kennedy Athletic, Recreational and Social Park at Kennedy Space Center on Merritt Island, Florida. The purpose of the demonstration is to evaluate various field-portable instruments that employ X-ray fluorescence (XRF) monitoring technologies. This demonstration plan describes the procedures that will be used to verify the performance and cost of the XRF instruments provided by these technology developers. The plan incorporates the quality assurance and quality control elements needed to generate data of sufficient quality to perform this verification. A separate innovative technology verification report (ITVR) will be prepared for each instrument. The ITVRs will present findings associated with each of the objectives of the demonstration.
