Slide presentation describing a 2015–2016 study to validate handheld XRF for measuring mercury (Hg) in soil. Preliminary 2015 results show a site-specific calibration (R2 ≈ 0.996), a 7.4 ppm detection limit (60 s), agreement with Method 7471A (R2 ≈ 0.995), and little moisture interference. 2016 tasks outline field validation, lab comparisons, accuracy quantification using NIST standards, and development of calibration checks.
