The National Institute for Standards and Technology (NIST) has recently released three soil standard reference materials that are uncontaminated (SRM 2709), moderately contaminated (SRM 2711), and highly contaminated (SRM 2710) with metals. The SRMs were analyzed at the U.S. Geological Survey (USGS) for thirty two major, minor and trace elements using a combination of wavelength dispersive X‐ray fluorescence spectroscopy (WDXRF) and inductively coupled plasma atomic emission spectroscopy (ICP‐AES). Good agreement is observed between NIST certified values and USGS results. The wide concentration ranges for most transition metals should make these SRMs useful in assessing the accuracy of methods used in geochemical exploration and environmental studies.
