This paper describes an approach for mapping soil-metal contamination using a real-time analytical method and geostatistical mapping techniques. The approach was tested on a confidential project. Analytical-quality, field-mobile, energy dispersive x-ray fluorescence spectrometry (EDXRF) was used to determine metals in soils. EDXRF has some advantages over other analytical methods because the instruments are more mobile, soil extracts are not necessary and EDXRF gives multi-element analysis in a range of a few parts per million to 100%. To evaluate the use of EDXRF for this project, the EDXRF results were compared to atomic absorption (AA) results on 196 split samples and several standard reference materials. The results show that analytical quality EDXRF can provide detection limits, accuracy and precision necessary for hazardous waste site investigations.
