  USEPA Regional Screening Levels (RSLs) View EPA RSLs  
  This source is the new king of screening levels. EPA got 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, and are upated as needed. 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 Regional Removal Management Levels (RMLs) View EPA RMLs  
  These are EPA levels used by EPA and states to support the decision to conduct a removal under CERCLA. Think of RSLs as "Do I need to assess futher?" and RMLs as "Do I need to do a removal action?". These are a tool only but a great one.  
  USEPA Soil Screening Guidance (SSG) View Soil Screening Guidance

  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.
