Incremental Sampling is a two-day course that provides an overview of incremental sampling concepts to address soil heterogeneity and obtain soil samples that are representative of the site. The course also includes an introduction to using X-ray fluorescence (XRF) in conjunction with incremental sampling to support real-time decision making for characterization and cleanup. By taking the course, participants will achieve the following objectives:

• Understand how soil heterogeneity affects data variability and how incremental sampling controls heterogeneity.
• Calculate common statistical parameters used to support quality control and analysis of incremental sampling.
• Build the introductory skills needed to plan, design, collect, and analyze incremental soil samples with robust data quality considerations.
• Understand the theory and operation of XRF and how it is used in the field to collect high-quality metal concentration data.
• Receive hands-on training for designing an incremental sampling approach, collecting incremental samples, calculating statistical parameters, and taking XRF measurements on prepared soil samples.

The training course uses a combination of lectures and interactive scenarios for participants to practice and discuss sampling design based on a site’s conceptual site model, present case studies and lessons learned for a variety of applications and contaminant scenarios and provide an opportunity for hands-on demonstration of incremental sampling and subsampling tools and approaches.
