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 Fall 2017. The updates primarily reflect relatively revisions to physiochemical constants used to develop the 2017 USEPA Regional Screening Levels and new information on TPH risk. A summary of updates and changes to previous editions of the EHE guidance is provided in Volume 2, Appendix 9. Revisions to action levels are not expected to significantly alter the results of past site investigations or site investigations currently underway.
The EHE guidance should be used in conjunction with HEER Office Technical Guidance Manual, which provides information on site investigation design and implementation as well as a an overview of the EHE process. Note that the EALs refer to U.S. Environmental Protection Agency (USEPA) Regional Screening Levels (RSLs) as one of numerous sources for soil, water and air screening levels. As stated in the USEPA 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. Other potential environmental hazards, including leaching and impacts to groundwater, vapor intrusion and gross contamination, have been incorporated into the EALs to allow for a more comprehensive review of contaminated properties without the need to assess these issues separately.

Comments and suggestions from the general public are welcome at any time. Updates will be posted to this website and notification sent to persons on the EAL mailing list. Workshops to present and discuss the EALs will also be held periodically. Please contact Roger Brewer with the HDOH HEER Office to provide comments or be included on the mailing list for updates and workshop announcements (firstname.lastname@example.org).
