The RML table will be updated following the updates to the RSL table which occurs approximately every 6 months. Consistent In Sep 2024, EPA's RSL tables were updated to provide the latest comparison values for residential and commercial/industrial exposures to soil, air, and tapwater (drinking water). The chemical-specific parameter values used in the VISL calculator follow the same hierarchy as used in the EPA's Regional Screening Levels for Chemical Contaminants at Superfund Sites calculator.

Applicability of the VISL Calculator The purpose of the VISL calculator is to provide a tool to assist RPMs, OSCs, risk assessors and others In such cases, EPA might refer the site for remedial action, or to a state or other authority, or might choose some other means of dealing with the site.
