“…Samples with large concentration differences from the threshold values for given elements allow on-site decisions to be made without having to wait for laboratory results. Unexpected or ambiguous results will prompt immediate complementary measurements, according to dynamic work plans (Robbat, 1997) or Adaptive Sampling and Analysis Programs (US- DOE, 2001, Horta et al, 2015.…”

In the last thirty years, portable X-ray fluorescence (pXRF) has grown from prototypes to being a key technique for field geochemical analyses, especially for mining and environmental applications. This technology provides real-time or near real-time decision support for operational field decisions (exploration, mining, site remediation or waste management), provides a cost-saving alternative to classical laboratory analysis programs, and deals efficiently with remote or harsh field conditions. The ability to rapidly collect a large number of samples and replicate analyses facilitates acquisition of higher data density compatible with geostatistics.pXRF can be used profitably for sample screening and selection tasks, dynamic sampling plans based on field observations and measurements, grid mapping of a site and determining relative element abundance. In waste management and remediation, pXRF is used to identify unknown waste composition, and verify waste loads before disposal or treatment.In all applications, having robust QA/QC plans and systematic laboratory controls on selected samples are essential for ensuring reliable measurements. The best overall results are usually achieved through a clever combination of field (pXRF) and lab data, with pXRF providing the bulk of the data at low cost, on larger data sets and potentially with better reliability than lab-based campaigns based on a limited number of samples.

“…Better sampling representativeness (data density) has been demonstrated to improve the level of confidence of site cleanup decisions by reducing uncertainty (Woll et al, 2003). When combined with fixed lab support for a subset of samples, both sampling and analytical error can be addressed.Two remaining components of the Triad Approach, systematic planning and dynamic work strategies, are needed to fully realize its potential (Crumbling et al, 2001;Robbat, 1997;USEPA, 2001).…”

The Triad Approach was field‐tested to determine if characterization objectives could be met for a brownfields property that had been identified as a future elementary school site. The new school is in response to a New Jersey Supreme Court ruling (the Abbott decision) that directed the state of New Jersey to fund school construction in poorer districts to expand physical facilities to relieve overcrowding. The Triad Approach is promoted by the United States Environmental Protection Agency as a process that has the potential to improve the timeliness and efficiency of site characterization, and the New Jersey Department of Environmental Protection (NJDEP) recently issued a policy statement supporting its potential. Aggressive school construction deadlines are contingent on property acquisitions that are relatively faster than the traditional investigatory process. In addition, given the future sensitive population, the investigations must be thorough. This case study is among the first studies to document the use of the Triad Approach for a future school site. The Triad Approach was used to define site conditions for six areas of concern in a two‐month time frame (from the start of the planning process to completed investigation). © 2004 Wiley Periodicals, Inc.
