Webinar – Background Check: The Why and How of Background Threshold Values

During environmental site assessments, background levels represent the concentrations of hazardous substances used as defensible reference points to determine whether a release has occurred. In an upcoming webinar, Dr. Kenneth S. Tramm will explain why understanding “background” is so important in the risk assessment process. He will outline the history of the Risk-Based Corrective Action (RBCA) process and its gaps in addressing background levels. While many states have slowly added background values for a select number of metals and radionuclides, the RBCA tools used by over half of the states in the U.S. still lack accessible values to allow simple screening during Phase II site investigation work. Even more problematic, some states have ultra-conservative risk criteria coupled with unrealistic background values that can confuse regulators and the regulated alike.

This webinar is essential for professionals involved in environmental due diligence, regulatory submissions, site investigations, and waste management. It will offer best practices and solutions to improve future site investigations and risk assessments.
