The Wisconsin DNR’s Remediation and Redevelopment Program has updated the numerical soil standards in its spreadsheet of residual contaminant levels (RCLs). The RCLs were determined using the recently-updated U.S. EPA regional screening level (RSL) web-calculator.

A summary of the changes to the direct-contact RCLs can be found in the new document, titled “RR Program’s Soil RCL Spreadsheet Update,” publication number DNR-RR-052f.

For more information and to access the RCL spreadsheet (macro and non-macro versions), visit the Resources for Environmental Professionals webpage and click on the “Soil RCLs” tab.
