X-Ray Fluorescence Soil Screening - REMC owns and has extensively used a Field Portable X-Ray Fluorescence Meter (XRF) to analyze the concentrations of metals in real-time on numerous sites. REMC has used the XRF for projects ranging from initial site assessment to guiding excavation equipment during CERCLA remediation projects. Real-time analysis provides substantial cost and time savings and allows decisions to be made in the field without having to wait for laboratory analytical results. REMC performs statistical comparison with analytical laboratory data to determine site- specific calibration curves.
