DEP's Contaminated Soils Forum was originally established in 1998 to provide an open forum for external and internal interested parties. In response to numerous requests, the forum has been re-established and renamed Contaminated Media Forum to provide that open forum and to come to consensus on how to apply the lessons learned from Risk Based Corrective Action (RBCA) implementation over the last several years.

Contaminated Media Forum

The Contaminated Media Forum serves as a venue for interested parties to discuss a wide variety of topics relating to evolving policy, scientific, and application issues associated with contaminated site cleanup and the re-use of a variety of media using risk-based management principles. Initial workgroups have been established to make recommendations on Background; Direct Exposure, Institutional Controls/Engineering Controls and Leachability; ECO Risk; and 62-777/CTLs. In addition, the forum will hold meetings throughout the state at later dates.

Next Contaminated Media Forum Meeting

Application of Direct Exposure Soil Cleanup Target Levels

The Department is posting this document for comment and discussion at the next Contaminated Media Forum Meeting:
Chapter 62-780, F.A.C., Supplemental Guidance for Application of Direct Exposure Soil Cleanup Target Levels for Subsurface Soils

Probabilistic Risk Assessment Subgroup

Notes and Materials from the 06/23/14 Meeting:

A follow up meeting will be scheduled for further discussion of PRA issues.

Original announcement and agenda

The recent changes to Chapter 62-780, F.A.C., to clarify the requirements for preparing Probabilistic Risk Assessments (PRAs) has led to the formation of a new subgroup of the Contaminated Media Forum to discuss issues regarding parameters and input assumptions for PRAs. Specific topics to be addressed are:

  • Testing the reliability of back-calculated outputs (run forward calculations to see if results match)
  • PRAs based upon both variability and uncertainty distributions and 2D-PRA approaches
  • Distributions (uniform, triangular, etc.) based on professional judgment due to lack of available data
  • Distributions for toxicity values and toxic equivalency factors
  • Exposure start age, and focus on protection of children for other exposure factors
  • Adjusting the soil ingestion distribution
  • Relative Bioavailability (literature-based variability distributions versus site-specific bioavailability studies)
