If you have a potentially impacted property or are conducting a screening for a property, please contact your local, state and/or federal agency for the most appropriate levels to use.			State Cleanup Levels
				International Cleanup Levels
		FEDERAL Guidance Documents and Values
	USEPA Regional Screening Levels (RSLs)		Get	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."	Get	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 Region 6 Medium-Specific Screening Levels (MSLs)		View	EPA Region 6 MSL Page
		Also replaced by the RSLs but provided for informational purposes. Tables have toxicity info and physical parameters in addition to the soil screening levels.
	USEPA Region 3 Risk-Based Concentrations (RBCs)		View	EPA Region 3 RBC Tables
		Region 3 seems to have its own table of the RSLs using the Region 3 name of Risk-Based Concentrations (RBCs) still. Also has FISH TISSUE SCREENING LEVELS.	Get	Fish Tissue Levels - pdf
			Get	Fish Tissue Levels - excel file
	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.
	Federal Drinking Water Standards and Health Advisories		View	MCLs and MCLGs

		Idaho is a state that once used company-developed software (was available for $17.95) similar to that which is required to buy in other states for hundreds of dollars. Beginning July 2004, it has developed a new approach, the REM, to address sites in the state. The approach includes FREE software (applause - see Editor's Note) to calculate risk-based target levels in addition to Initial Default Target Levels (IDTLs). The manual and software are free after a simple registration.
