How can I use MARSSIM?

One of the many benefits to using the MARSSIM system is its adaptability. It is used for final status surveys at many sites throughout the United States, but it can also be used to demonstrate compliance with dose-based or risk-based requirements for scoping, characterization, and remedial action surveys. The developers of MARSSIM intended to make the system flexible, and because of this, relied on a performance-based approach in conjunct with systematic planning and a Data Quality Objectives process. Together, these methods allow users to develop a tailored survey process rather than having to rigidly adhere to a single prescriptive method.
