Full‐scale in‐situ biobarrier demonstration for containment and treatment of MTBE

AbstractThe Naval Facilities Engineering Service Center (NFESC), Arizona State University, and Equilon Enterprises LLC are partners in an innovative Environmental Security Technology Certification Program cleanup technology demonstration designed to contain dissolved MTBE groundwater plumes. This full‐scale demonstration is being performed to test the use of an oxygenated biobarrier at Naval Base Ventura County, in Port Hueneme, California. Surprisingly, few cost‐effective in‐situ remedies are known for the cleanup of MTBE‐impacted aquifers, and remediation by engineered in‐situ biodegradation was thought to be an unlikely candidate just a few years ago. This project demonstrates that MTBE‐impacted groundwater can be remediated in‐situ through engineered aerobic biodegradation under natural‐flow conditions. With respect to economics, the installation and operation costs associated with this innovative biobarrier system are at least 50 percent lower than those of a conventional pump and treat system. Furthermore, although it has been suggested that aerobic MTBE biodegradation will not occur in mixed MTBE‐BTEX dissolved plumes, this project demonstrates otherwise. The biobarrier system discussed in this article is the largest of its kind ever implemented, spanning a dissolved MTBE plume that is over 500 feet wide. This biobarrier system has achieved an in‐situ treatment efficiency of greater than 99.9 percent for dissolved MTBE and BTEX concentrations. Perhaps of greater importance is the fact that extensive performance data has been collected, which is being used to generate best‐practice design and cost information for this biobarrier technology. © 2001 John Wiley & Sons, Inc.

OHMSETT 2000: FISCAL YEAR IN REVIEW

ABSTRACT During fiscal year 2000, a series of, boom, skimmer, pump, and dispersant tests were performed at OHMSETT, the national oil spill response test facility. Spill response technology development and training sessions were also conducted. These projects were conducted by government organizations, including the U.S. Coast Guard (USCG) Research and Development Center and the U.S. Navy Naval Facilities Engineering Service Center (USN ?FESC); research organizations such as Environment Canada, S.L. Ross Environmental Research, and the University of New Hampshire (UNH); and other private companies. The USCG and the National Spill Control School of Texas A&M University-Corpus Christi continued training sessions on the handling of oil spill response equipment. The USCG Research and Development (R&D) Center sponsored a test on viscous oil pumping systems, and another test for the development of fast-water oil spill containment and cleanup equipment. The NFESC conducted an evaluation of four high-speed skimmers that involved testing in waves with light fuel oils. Private companies utilized the tank and its simulated beach system to test their new containment boom designs and multi-skimmer units for oil retention and recovery capabilities. UNH returned to gather performance data on a new rapid current oil barrier design. Each of these projects has been significant in advancing oil spill response technology.

Remediation Technologies Screening Matrix and Reference Guide: Version III

AbstractThe U. S. Army Environmental Center (USAEC) is leading an effort to update the Remediation Technologies Screening Matrix and Reference Guide, Third Edition under the auspices of the Federal Remediation Technologies Roundtable (FRTR). Its purpose is to create a comprehensive “Remediation Technologies Yellow Pages” for use by those responsible for environmental cleanup. The Guide is being produced as a multiagency cooperative effort published under the FRTR. Members of this effort include USAEC, the U. S. Army Corps of Engineers (USACE), the Naval Facilities Engineering Service Center (NFESC), the Air Force Center for Environmental Excellence (AFCEE), the Environmental Protection Agency (EPA), the Department of Energy (DOE), the Department of the Interior (DOI), and the Interstate Technologies Regulation Cooperative (ITRC). This article provides a comprehensive look at environmental technology information provided in the electronic user‐defined Remediation Technologies Screening Matrix and Reference Guide.
