Incremental Sampling is a two-day course that focuses on the theory and application of ITRC’s Incremental Sampling Methodology (ISM), composite sampling designs, and hybrids of the two. IS hybrid designs are useful to address multiple project goals simultaneously. Since “representativeness” is a key aspect of data quality and ISM/IS data are demonstrably more representative than most discrete data, it will be argued that IS data are indeed “better” than non-IS data. The course will answer questions such as:

• What is the difference between ITRC’s ISM and EPA’s Incremental Sampling (IS) strategies?
• Is there written EPA guidance? What features should an ISM or IS design have?
• Can IS give project risk assessors the data they want, while simultaneously meeting the RPM’s own data needs for characterization or remedial design?
• How are background concentrations determined and comparisons to background handled using IS?
• do we know whether IS “worked” for the project?
