How the community value of ecosystem goods and services empowers communities to impact the outcomes of remediation, restoration, and revitalization projects (PUBLISHED REPORT)
Remediation to Restoration to Revitalization (R2R2R) is a place-based practice that requires ongoing communication amongst agencies, local governments, and citizens. Each of these entities have different relationships with and responsibilities to sites where R2R2R progresses. Se...
Evaluation of Atmospheric Water Generation Technology: Microbial Water Quality (PUBLISHED REPORT)
Atmospheric water generators (AWGs) have the potential to expand the availability of water during shortages, contamination events and interruptions of service. Given the nature of atmospheric water generation (i.e., condensation of atmospheric water vapor), high quality produced ...
Analysis of the Causes of a Decline in the San Joaquin Kit Fox Population on the Elk Hills, Naval Petroleum Reserve #1, California (PUBLISHED REPORT)
EPA is announcing the availability of the final report, <i>Analysis of the Causes of a Decline in the San Joaquin Kit Fox Population on the Elk Hills, Naval Petroleum Reserve #1, California</i>. This report describes a causal assessment of the decline in the abundance of San Joaq...
Leak, Purge, and Gas Permeability Testing to Support Active Soil-Gas Sampling (PUBLISHED REPORT)
Active soil-gas sampling has been used as a reconnaissance method in support of soil and groundwater sampling of volatile and biodegradable organic compounds for over 30 years. More recently, soil gas sampling has been used directly to evaluate risk posed by vapor migration from ...
Exposure Factors Handbook Chapter 3 (Update): Ingestion of Water and Other Select Liquids (PUBLISHED REPORT)
This update includes new information and factors on nonchemical-specific information used to assess human exposure to environmental contaminants that has become available since the <em>Exposure Factors Handbook: 2011 Edition</em> was released. The recommended values have been rev...
A REPORT ON USING FORWARD LOOKING INFRARED RADIATION (FLIR) TECHNOLOGY AS AN EFFECTIVE PCE/TCE SCREENING TOOL FOR VAPOR INTRUSION SAMPLING (PUBLISHED REPORT)
The information in this document is from a collaborative effort between the U.S. EPA, Region 6 Superfund Division and the Office of Research and Development, National Risk Management Research Laboratory. Research was conducted at the US EPA Region 6 Addison Texas Facility. The fi...
Determination of As-Discarded Methane Potential in Residential and Commercial Municipal Solid Waste (PUBLISHED REPORT)
The objective of this research was to measure methane potential (Lo) in commercial and residential waste samples obtained from waste collection vehicles at the point of disposal. Previously reported Lo values span a wide range including estimates substantially lower than the cur...
