The document includes a discussion of: 1) the general forensic approach including relevant background information and benefits to Department of Defense (DoD); (2) a general summary of the technical methods that are used in a PCB environmental forensics investigation; and (3) a summary of the application of the described procedures in two demonstration case studies.

Mention of specific product names or vendors or source of information does not constitute an endorsement by any of the authoring organizations. The information pertaining to the technology performance was collected from various sources including consultant's reports, government documents, conference proceedings, Environmental Security Technology Certification Program (ESTCP) reports, and more. The source of the information is LIST OF TABLES GENERAL FORENSICS APPROACH IntroductionDefining the source of anthropogenic contamination from military facilities into sediments can be a difficult task. This is particularly true in waterways and coastal settings where multiple point sources are present along with persistent non-point sources such as urban background. This situation often results in com...
The experimental work consisted of melting and testing of exploratory alloys. Past work indiuated that the addition of the beta stabilizing elements ouch as chromium, iron, manganese, molybdenum, and vanadium, offered the best possibility in the develolpent of titanium alloys. This observation was verified when ternary and complex alloys containing these elements were tested and found to pussess desirable properties, iii

The total Center Hill drainage area is 2,174 square miles. Because the average slope of the reservoir is over 3 feet per mile, the 18,000-acre lake to be prone to rapid water-level rises. The total storage area exceeds 2 million acre-feet. The reservoir provides flood risk reduction, navigation, hydropower, recreation, water supply, and water quality benefits. The dam contains three hydropower units with a combined capacity of 135,000 kilowatts.Center Hill Dam is a 248-foot high combination concrete-earthen embankment dam with foundation seepage issues stemming from original construction flaws. The embankment portion of the dam was placed directly on a mature karst limestone with little to no foundation treatment. (2) the basis for the comment; (3) the significance of the comment (high, medium, or low); and (4) recommendations on how to resolve the comment. Overall, 12 Final Panel Comments were identified and documented. Of these, two were identified as having high significance, six had medium significance, and four had low significance. Results of the Independent External Peer ReviewThe panel members agreed among themselves on their "assessment of the adequacy and acceptability of the economic, engineering, and environmental methods, models, and analyses used" (USACE, 2012a; p. D-4) in the Center Hill Dam Supplemental MRER review documents. Based on the Panel's review, the report is well constructed to support a plan of action that would allow the Center Hill Dam to be reclassified from USACE's DSAC I rating to a DSAC IV. The documents demonstrate that the project has had fundamental problems due to the original construction and that USACE has taken steps to address the problems in a timely and effective manner by developing solutions that are likely to be generally effective at minimum cost. The Panel agreed that USACE used appropriate methods and models in its analysis and provided adequate detail in describing the processes followed throughout the project. While the Panel deemed the report comprehensive with robust documentation in many areas, it identified areas of inconsistencies attributed to recent updates to the report and a few areas where additional clarification is warranted. The Panel is also...
