Human Health Medium-Specific
Screening Levels

Welcome to the Region 6 Human Health Media-Specific Screening Level website. The downloadable tables were developed jointly with DOE's Oak Ridge National Laboratory (ORNL) under an Interagency Agreement as an update of the EPA Region 3 RBC Table, Region 6 HHMSSL Table and the Region 9 PRG Table. Regions 3, 6, and 9 have historically published screening values on the internet and worked together to develop a consensus based approach to developing a screening table. The new tables also include a calculator function. Please check with your program before using the calculator to determine its appropriateness for your situation and/or site.

The tables were not generated to represent action levels or cleanup levels but rather as technical tools. The responsibility of their use and relevance to site-specific circumstances becomes the responsibility of the person recommending their use and the user of the table.

You will need the free Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more.
