TOPEKA – The Kansas Department of Health and Environment (KDHE) Bureau of Environmental Remediation (BER) has released the 6th version of the Risk-based Standards for Kansas (RSK) Manual. The RSK Manual was originally developed in 1999, to address contaminated sites fairly and consistently in Kansas in the appropriate state cleanup programs. Chemical-specific and media-specific risk-based cleanup goals listed in the RSK Manual are calculated by using guidance and directives from the US Environmental Protection Agency (USEPA) and other technical resources.

Revisions for the 6th version include the addition of cleanup goals for ammonium glufosinate and dalapon and the updating of exposure factors utilized in calculations, per USEPA guidance. The 6th version of the RSK Manual can be found at https://www.kdheks.gov/remedial/rsk_manual_page.html
