Now Available – Two Publications: Guidance: Contaminated Soil Quick Reference Table (RR-106) And Guidance: Soil Residual Contaminant Level (RCL) Spreadsheet (RR-0151)

Posted on by Coreen Fallat

Following a public comment period two publications are now posted and available online at the RR Program’s Contaminated Soil and Sediment  webpage: 

  • Guidance: Contaminated Soil Quick Reference Table (RR-106) 
  • Guidance: Soil Residual Contaminant Level (RCL) Spreadsheet (RR-0151) 

The purpose of the publications is to provide resources for externals to look up soil residual contaminant levels, or RCLs, that are developed using standard equations in the U.S. Environmental Protection Agency (EPA) Regional Screening Level (RSL) Calculator. 

The DNR updated the publications in response to the U.S. EPA’s May 2024 update to its RSLs. Screening levels for 18 contaminants changed since the last update to the DNR’s publications in 2018. Ten common contaminants were added to the Soil RCL Spreadsheet and it also incorporates a cumulative risk calculator for carcinogenic polycyclic aromatic hydrocarbons (cPAHs).

Questions on the publications may be submitted to Erin Endsley at Erin.Endsley@wisconsin.gov.

Additional documents and guidance from the Remediation and Redevelopment Program may be found using the search tools available on the publications and forms webpage.
