The Wisconsin DNR updated the numerical soil standards, or residual contaminant levels (RCLs), in the Remediation and Redevelopment program’s spreadsheet of RCLs to reflect the US EPA June 2016 update to its Regional Screening Level (RSL) website. The RR Program RCL Spreadsheet Update (RR-052d) provides a summary of the updates incorporated in the June 2016 spreadsheet.

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