Frequent Questions

When should I choose a value for the LBGR?

You should choose a preliminary value of the LBGR before remediation and a final value of the LBGR as you complete the Final Status Survey design. There are a number of factors that determine the final value of the LBGR. In some cases, you will want to remediate to concentrations sufficiently below the DCGLW, so you can demonstrate the survey unit meets the release criterion.

See, Chapter 5: Survey Planning and Design and Chapter D: The Planning Phase of the Data Life Cycle on the MARSSIM Manual download page.
