The purpose of this website is to provide a screening level calculation tool to assist risk assessors, remedial project managers, and others involved with risk assessment and decision-making at CERCLA sites in developing or refining screening levels. The recommended approach for developing remediation goals is to identify screening levels at scoping, modify them as needed at the end of the RI or during the FS based on site-specific information from the baseline risk assessment, and ultimately select remediation levels in the ROD. Laboratory Reporting Limits It is important to consult with the laboratory when planning a soil gas, sub-slab, or indoor air sampling event to ensure that the reporting limits i.

Regional Screening Level Tables. The EPD compliance officer assigned to the site should be the first point of contact. Here you will find tables of risk-based screening levels, calculated using the latest toxicity values, default exposure assumptions and physical and chemical properties, and a calculator where default parameters can be changed to reflect site-specific risks.
Screening level development and screening should assist staff in streamlining the consideration of remedial alternatives. This tool presents standardized risk-based screening levels and variable risk-based screening level calculation equations for chemical contaminants.

Such conditions include USEPA g : Very shallow groundwater sources for example, depths to water less than 5 ft below foundation level Shallow soil contamination vapor sources for example, sampled at levels within a few feet of the base of the foundation Buildings with significant openings to the subsurface for example, sumps, unlined crawlspaces, earthen floors or significant preferential pathways, either naturally-occurring or anthropogenic not including typical utility perforations present in most buildings Chemical Parameters Toxicity values and other chemical parameters needed for calculating screening levels and running the Johnson and Ettinger Model should generally be taken from the most recent version of the USEPA Regional Screening Level RSL Tables.
If the calculator is used with non-default inputs in a decision on a Superfund site, it is recommended that the inputs be clearly identified and justified by the user.
