New Documents

Survey of Technologies for Monitoring Containment Liners and Covers (EPA 542-R-04-013). This report, published by the EPA Office Superfund Remediation and Technology Innovation, provides information on innovative long-term monitoring technologies to detect contaminant releases beneath a liner containment system and identify potential problems with the integrity of final containment covers. The report summarizes available information on these technologies and provides examples of where the technology has been used (June 2004, 64 pages). View or download at http://clu-in.org/techpubs.htm or http://www.epa.gov/tio.

Fingerprint Analysis of Contaminant Data: A Forensic Tool for Evaluating Environmental Contamination (EPA 600-5-04-054). This issue paper was produced through EPA’s Technical Support Center. It describes a tool to identify detection monitoring parameters for specific industries. The Fingerprint Analysis of Leachate Contaminants (FALCON), was developed in response to the need for identifying the source of contaminant plumes. The objective of this paper is to demonstrate that FALCON is a quantitative, defensible fingerprinting process (May 2004, 27 pages). View or download at http://www.epa.gov/tio/tsp/issue.htm .

Introduction to Energy Conservation and Production at Waste Cleanup Sites (EPA 542-S-04-001). This issue paper, prepared by EPA’s Engineering Forum under the Technical Support Project, provides an overview on the considerations for energy conservation and production during the design and operation and maintenance (O&M) phases of waste cleanup projects. The paper presents four case studies highlighting energy conservation or production, including a site using landfill generated methane gas directed to operate microturbines. The issue paper also introduces an energy checklist as a suggested tool to help project managers consider energy conservation or production at their sites (May 2004, 36 pages). View or download at http://www.epa.gov/tio/tsp/issue.htm .

Handbook of Groundwater Protection and Cleanup Policies for RCRA Corrective Action - April 2004 - Updated Version (EPA530-R-04-030). This document was produced by the EPA Office of Solid Waste. It contains the Environmental Protection Agency's (EPA's) latest interpretation of policies on such topics as cleanup goals, the role of groundwater use, point of compliance, source control, and monitored natural attenuation. This Handbook ties 15 different topics together with an overall Groundwater Protection and Cleanup Strategy that emphasizes a phased, results-based approach to cleaning up contaminated groundwater (April 2004, 102 pages).

Phytoremediation of Groundwater at Air Force Plant 4: Carswell, Texas (EPA 540-R-30-506). This report was produced by the U.S. EPA Superfund Innovative Technology Evaluation (SITE) program. This Innovative Technology Evaluation Report (ITER) describes demonstration results from an investigation of the ability of planted eastern cottonwoods to remediate shallow TCE groundwater in a subhumid climate. The study was undertaken to determine the potential for a planted system to hydraulically control the migration of contamination as well as to biologically enhance the subsurface to promote in situ reductive dechlorination (September 2003, 89 pages).

Cyclodextrin-Enhanced In Situ Removal of Organic Contaminants from Groundwater at Department of Defense Sites (CU-0113). This cost and performance report was produced under the DoD Environmental Security Technology Certification Program (ESTCP). This technology demonstration was intended to show the potential of cyclodextrin enhanced flushing (CDEF) under near full-scale operational conditions. The particular objectives of this demonstration were (1) evaluation of the cost and performance of cyclodextrin-enhanced removal of dense nonaqueous phase liquids (DNAPL) from polluted groundwater, (2) test unrefined liquid cyclodextrin (CD) as a substitute for CD powder, (3) evaluate membrane technology for recovering and reusing CD, (4) identify the most appropriate wastewater treatment technologies, and (5) conduct partition tracer test (PTT) for mass balancing (May 2004, 101 pages).

Heat as a Tool for Studying the Movement of Ground Water Near Streams (USGS Circular 1260). This U.S. Geological Survy report describes the general principals and procedures by which the natural transport of heat can be utilized to infer the movement of subsurface water near streams. This information sets the foundation for understanding the advanced applications in chapters 2 through 8. Each of these chapters provides a case study, using heat tracing as a tool, of interactions between surface water and ground water for a different location in the western United States. Technical details of the use of heat as an environmental tracer appear in appendices (Spring 2004, 105 Pages). View or download at http://water.usgs.gov/pubs/circ/2003/circ1260/ .
