Technical Services - Risk Assessment and Hydrology
National Information
Our mission is to provide state-of-the-art
information and
expertise in the areas of human and ecological risk
assessment,
hydrogeology, pollution prevention, and
other technical areas. Our goal
is to provide the site
and facility cleanup staff, other EPA, state, and
public
stakeholders the best available scientific information for
document
development and decision making.
September 2008 Update: EPA released a Regional Screening Table back in May of 2008. The Regional Screening Table (RSL) has replaced the Region 3 RBC table, the Region 6 Screening Level table, and the Region 9 PRG table. The RSL was updated and the website location has been changed. Region 4 recommends the use of the Regional Screening Level table for all risk assessment screening on Superfund projects.
