USEPA Regional Screening Levels (RSLs) View EPA RSLs
This source is the new king of screening levels. EPA got all Regions 3, 6 and 9 together and, in 2009, came up with these. There are residential and industrial screening levels for soil, air and tap water. EPA regions still have their old screening levels on their websites but with notices to use these. The site also contains a Screening Level Calculator to assist in calculating site-specific screening levels and links to the California Human Health Screening Levels. Good job EPA!!"
USEPA Soil Screening Guidance (SSG) View Soil Screening Guidance
An older source but one of the building blocks for screening levels. This website gives you the older soil screening levels (SSLs), information on how site screening levels used to be calculated, and the general guidelines EPA used in the past for sites." Generic SSLs
USEPA Region 9 Preliminary Removal Goals (PRGs) View EPA Region 9 PRGs
This source, called R9 PRGs for short, was the king of PRGs for years. Now EPA recommends use of the new RSLs. But we present them here for informational purposes.

USEPA RAGS: Part B, Preliminary Removal Goals (RAGS, Part B) View RAGS Part B - PRGs
RAGS Part B is the holy grail of screening levels. Simple document that gives the general risk (intake) equations used in a quantitative risk assessment and the general equations for screening levels termed PRGs (just a note: people use the acronym PRGs for preliminary removal goals, preliminary remedial goals AND preliminary remediation goals....generally we are talking about the same thing). No actual soil levels but does have the original exposure default values used in EPA risk assessments and general calculations of the goals. Examines various pathways and media, though mostly for use with soil. Some of the inhalation defaults have changed since this was written, but it is still a must have for those attempting to determine their own screening levels.
