Pennsylvania’s Department of Environmental Protection (PADEP) issued the “Land Recycling Program Technical Guidance Manual for Vapor Intrusion into Buildings from Groundwater and Soil under Act 2” this summer and the document will become final in November 2016.  This 103-page Technical Guidance Manual outlines significant changes and replaces the original Technical Guidance Manual dated January 24, 2004.

As this is the first substantial change to the guidance in over twelve years, it is important to understand changes and how they might affect your site or remediation plan. Some of the key changes to the guidance include VOC mitigation requirements, soil and groundwater screening levels and methods, and vapor intrusion modeling guidance.

A full version of PADEP’s guidance document can be found at the Land Science’s Resource Page, as well as other national and federal guidance documents and other state guidances.  Have additional questions? Contact Land Science, we have a team dedicated to vapor intrusion and mitigation solutions.
