U.S. EPA, Office of Superfund Remediation and Technology Innovation, OLEM Directive 9200.2-141, 20 pp, 2018

U.S. EPA has addressed the role of background concentrations in the Superfund site assessment and remediation processes in a variety of guidance documents. OSRTI has compiled excerpts and citations from relevant guidance documents into a set of frequently asked questions (FAQs) to answer basic questions about the definition and use of background data, including how a background dataset is generally developed and used in the different stages of site assessment and remediation. This document does not establish new guidance. Part Two: Statistical Concepts is still in development. https://semspub.epa.gov/src/document/HQ/100001657
