Environmental Hazard Evaluation and Environmental Action Levels
The document Screening For Environmental Hazards at Sites With Contaminated Soil and Groundwater is a technical report that can be used to expedite the identification of potential environmental hazards at sites with contaminated soil and groundwater as well as assist in the cleanup and redevelopment of these properties. The most current edition of the EHE guidance is dated Summer 2016. The original version of the Summer 2016 edition was updated in November 2016 to correct errors in the soil leaching model and make additional edits to the lookup tables and EAL Surfer (refer to Update worksheet notes in the EAL Surfer). The EHE guidance should be used in conjunction with Section 13 of the HEER Office TGM which covers EHE guidance. Note that the EAL document incorporates U.S. Environmental Protection Agency (USEPA) Regional Screening Levels as one of numerous references for published soil, water and air action levels. As discussed the RSL guidance user’s manual, the USEPA RSLs cannot be used as a stand-alone tool to evaluate the need for additional actions at contaminated sites. The USEPA RSLs only address direct exposure of humans to contaminants in soil, and other potential environmental hazards are not considered. Although not required, use of the guidance is strongly recommended. The sections of the guidance can be downloaded below.
A summary of updates and significant changes to previous editions of the EHE guidance is provided in Volume 2, Appendix 9. Revisions to action levels for common contaminants are not expected to significantly alter the results of past site investigations or site investigations currently underway. The EHE guidance and associated references can be downloaded below.
