Description:
Objective:This final report executive summary is prepared in partial fulfilment of the requirements for the EPA Assistance Agreement R-828598-01 between Lamar University Gulf Coast Hazardous Substance Research Center (GCHSRC) and the US Environmental Protection Agency (EPA). This Agreement covers a period of four years from September 1, 2000 through August 31, 2004 and the total amount of the Agreement is $5,937,250.00. During the Agreement period, the GCHSRC has supported a total of 33 general research projects and 5 technology transfer projects that address a wide range of environmental needs associated with Gulf-Coast industries. The supported general research projects were focused in all three of the Center’s major focus areas that include site remediation, pollution prevention, and waste treatment. The supported technology transfer projects were on pilot-scale demonstrations of treatment and control technologies developed through the general research program. All the supported projects under this Agreement were carried out at the Center’s nine member universities. The list and the technical description of the supported projects are included in the final report.
Summary/Accomplishments (Outputs/Outcomes):The Center supported projects in both General Research Program and Technology Transfer Program under this Agreement. The General Research Program funded 33 projects distributed among the nine member universities as follows: Lamar University-5; University of Houston-5; Rice University- 4; Texas A&M University-4; The University of Texas-6; Louisiana State University-4; Mississippi State University-2; University of Alabama-2; and University of Central Florida-1. The Technology Transfer Program funded 5 projects: University of Houston-1; Rice University-1; Texas A&M University-1; and University of Central Florida-2. The funded projects are listed in the section below.
While the executive summary for each funded project is available and separately reported, the significant accomplishments from the funded projects are summarized below. In general, the funded projects have achieved various degree of success in terms of the objectives, goals and milestones set up for the projects. The accomplishments related to the educational component have included the training of undergraduate students, graduate students and post-doctoral fellows; related to the technology transfer component have included theses and dissertation completion, paper publication and conference presentation; and related to the commercialization component have included patent application and the commercialization of the developed technology. Many funded projects have received substantial amount of follow-up grants as the results from the GCHSRC funding support. Specifically, the achievements for the funded projects are summarized below:
UHH687 | Improved Halogen Resistance of Catalytic Oxidation through Efficient Catalyst Testing We constructed equipment which is still available for work in this area, and disseminated the results through two theses and through presentations. The IP we developed in this area is now represented in seven issued US patents, and pending foreign counterparts, and has been widely licensed and sublicensed. The technology we worked on is now widely practiced, and is expected to reduce the costs and pollution burden of chemicals ranging from small organics to polymers. We also trained students who are continuing to work in this area, advancing the level of US technical prowess in catalysis and high- throughput screening. |
TAM696 | Phytoremediation and Bioremediation of Land Contaminated By PAHs, PCBs, and TNT The results of this research indicate that plants may not immediately enhance soil remediation of hydrocarbons in freshly contaminated soils. These results suggest that freshly contaminated soils at low initial concentration may have sufficient natural bioremediation mechanisms already in the soil and plants do not necessarily enhance remediation. However, plants may be beneficial aesthetically and also assist by stabilizing the soil and preventing transport through water and wind erosion. The project has generated 21 publications as listed in the project’s executive summary. |
LUB697 | Fundamental and Kinetic Investigation of Sorbent Technology for Optimum Mercury Emission Control The project has provided the public and the mercury research community with critically-needed scientific information regarding mercury behavior during activated carbon adsorption. The information is expected to lead to the development of an efficient mercury control technology beneficial to the environment and the society. The project has lead to additional funding of more than $600,000 from other funding agencies and generated 16 publications. |
RUH700 | Effects of Natural Cyclic Variations on Contaminated Fate and Transport The study provides the scientific community with a greater understanding of the physiochemical processes of sediment-contaminant interaction. A primary consideration in sediment clean-up is when to stop, or how clean is acceptable. Present mathematical models assume that as long as a clean-up operation continues that the contaminant concentration will be steadily reduced toward zero. Two Ph.D. students and one MS student graduated from this program. In addition, the project has generated 20 publications. |
RUH703 | Effects of Natural Cyclic Variations on Contaminated Fate and Transport The work represented fundamental scientific advance with the promise to reduce the cost of hazardous waste remediation. Experiments investigating the potential for dechlorinating anaerobes to enhance dissolution rates of PCE from a non-aqueous phase liquid (NAPL) were completed during the funding period. This project has led to the demonstration project RUH846: Quantitative Demonstration of Source-Zone Bioremediation in a Field-Scale Experimental Controlled Release System. It has also generated 12 publications. |
UTA722 | The Effects of an Oily-Phase on VOC Emissions from Industrial Wastewater It is expected that the results of this work will provide improved estimates of VOC emissions from industrial wastewater through modifications of existing models such as WATER9 and TOXCHEM+, since past work completed by Dr. Corsi and funded by the GCHSRC has lead to significant revisions to those models. Industry's reliance on WATER9 and TOXCHEM+ as alternatives to direct measurement of volatile hazardous air pollutant emissions from on-site sewers and treatment plants (required NESHAPs) is estimated to save industry tens of millions of dollars each year. This project has generated two MS theses and one publication. |
UTA724 | Mercury Removal from Stack Gas by Aqueous Scrubbing with Injection of Chlorine Oxidants This work has provided a process concept for controlling mercury emission from combustion gases, such as coal-fired poser plants. The results of this study demonstrate that mercury can be scrubbed from plant flue gas by chlorine injection in the presence of water. However, the injection of chlorine appeared to enhance mercury desorption from limestone slurry. Previous researchers have observed the mercury re-emission phenomenon. However, in this study, the injection of chlorine appeared to increase the mercury re-emission rate from limestone slurry with increasing chlorine concentration. |
UTA725 | Transport, Fate and Risk Implications of Environmentally Acceptable Endpoint Decisions This work has provided a process concept for controlling mercury emission from combustion gases, such as coal-fired poser plants. The results of this study demonstrate that mercury can be scrubbed from plant flue gas by chlorine injection in the presence of water. However, the injection of chlorine appeared to enhance mercury desorption from limestone slurry. The project has generated four publications. |
UHH725 | Transport, Fate and Risk Implications of Environmentally Acceptable Endpoint Decisions This is a collaborative study with UTA725 to develop a risk-based approach which will be a significant improvement over the current approach for estimating acceptable soil concentrations that will protect water quality uses at a downstream groundwater receptor. The work has provided a process concept for controlling mercury emission from combustion gases, such as coal-fired poser plants. The project has generated four publications. |
RUH731 | Development and Application of a Real-Time Optical Sensor for Atmospheric Formaldehyde An optical sensor has been developed capable of quantification of atmospheric levels of formaldehyde with a precision of 0.5 ppbV. Three field campaigns have been undertaken and the data have been used in follow-up research to validate the models that predict ozone and formaldehyde generation from photochemical smog reactions. The project has received a follow-up grant entitled “Postdoctoral position in environmental monitoring technology development” from the Dreyfus Foundation in July 2000 with a total funding of $96,000. The project has also led to four publications and six presentations. |
LSU734 | An Advanced System for Pollution Prevention in Chemical Complexes The study has concluded that Hierarchical Pareto Optimization can be successfully used for economic and environmental analysis of Industrial Ecosystems. This methodology provided a modular structure for the entire analysis, which makes it very flexible. A case study conducted during this research work shows that the EPA LCA methodology TRACI can be used successfully to analyze the environmental impacts of an industrial ecosystem. The study has generated nine publications/presentations. |
LUB734 | An Advanced System for Pollution Prevention in Chemical Complexes This is a collaborative study of LSU734 to develop an Advanced System for Pollution Prevention in collaboration with engineering groups at IMC Agrico Monsanto Enviro Chem and Motiva (Star/Texaco) Enterprise and to ensure it meets the needs of the chemical and petroleum refining industries. The study has concluded that Hierarchical Pareto Optimization can be successfully used for economic and environmental analysis of Industrial Ecosystems. This methodology provided a modular structure for the entire analysis, which makes it very flexible. A case study conducted during this research work shows that the EPA LCA methodology TRACI can be used successfully to analyze the environmental impacts of an industrial ecosystem. The study has generated nine publications/presentations. |
LUB744 | Optical Fibers coated With Titania Membrane/UV Generating Crystal in a Distributed-Light Photoreactor for VOC Oxidation The study has concluded that the mechanisms for NLO to benefit may be three-fold: First, NLO would contribute to PCO by transmission, i.e., as a waveguide to transmit the light energy into the inner layers. Second, it may be due to the perovskite or ferroelectric behavior (net electric dipole moment) that impedes electron-hole recombination. Three, other electrical, magnetic, and optical properties such as electric field-induced scattering may enhance light utilization within the catalyst. This research has led to the external grant: "Super-Porous Titania/NLO-Coated Fiber Optic Photoreactor for Environmental Applications" from ARP/ATP Texas Higher Education Coordinating Board, 003581-0019-1999, $154,000, 2000-2003. The study has also led to seven publications/presentations. |
LUB749 | Characterization and Modeling of Indoor Particulate Contaminants In a Heavily Industrialized Community The project has provided the public and the particulate matter research community with scientific insights regarding PM behaviour in Southeast Texas. The information is critically needed in the effective management of PM pollution leading to a cleaner environment. The accomplishments of the project have included seven additional funded projects from the Texas Commission on Environmental Quality, the Texas Air Research Center, and the Department of Agriculture through Sul-Ross University worth $722,050. In addition, eleven papers describing the project results have been published, presented or accepted for presentation. |
LSU753 | Adsolubilization and Photocatalysis in a Semiconducting Monolithic Reactor for Wastewater Treatment The results have showed the optical fiber monolithic reactors are promising. Modeling efforts are currently progressing in order to allow the scale-up of this process. The long term operation (60 hrs) only showed a slight decrease of the removal efficiency of the phenanthrene and DCB which suggested it had no significant impact on the fate of titania film on the cordierite ceramic monolith or the quartz optical fiber. The titania film did not degrade after prolonged use in the reactor. This project has produced five peer-reviewed publications and five conference presentations during the three years of funding. It is also the basis for 1 Ph.D. thesis which will be defended this summer. The project has produced data and ideas that have formed the basis for one proposal that is currently under review by the NSF. Another proposal is being submitted to ONR. |
LSU754 | Remote Detection of Gas Emissions in Industrial Processes The automatic gas detection phase methods have been developed for automatically detecting a target gas in a hyperspectral image. The best method for actual testing is to detect weak signals by first applying a clustering algorithm to segment the image into different regions before applying the detection filter. The project has led to one conference presentation. |
LSU759 | Searching for Optimum Composition of Phosphogypsum: Fly Ash: Cement Composites for Oyster Culch Materials The research has shown that the combinations of 77%:20%:3%, 72%:25%:3%, 67%:30%:3%, 63%:35%:2% PG: Class C fly ash: Portland type II cement composites met the 2.0×10-13 m2·s-1 criteria for effective calcium and sulfate diffusion coefficients. This research has provided baseline data, which allowed the research team to solicit additional funds from the Florida Institute of Phosphate Research (FIPR). A small grant of $10,000 was received from FIPR to investigate the regulatory permitting process through USEPA for the use of phosphogypsum in the environment. If the LSU research team is successful in getting a permit approved (or waived), FIPR will fund a larger grant (approximately $350K) to investigate the use of the stabilized phosphogypsum as fill material in coastal protection devices. Several manuscripts are being prepared from the project. |
MSU761 | Development of a Phytologically-based Biosorptive Water Treatment Process This project has yielded results that indicate great potential for this process to effectively treat contaminated fluids at a reduced cost. Particularly of interest is the simplicity of the process in terms of its operation which should provide small companies with an additional option for treating their waste streams. MSU has filed for a patent for the process that was further developed under this funding. KenGro Inc. (Charleston, MS) working in collabortion has received an USEPA SBIR for commercialization of this process. MSU has also received $60K and $40K, respectively, for development of this process from the Mississippi Water Resources Research Institute and the USDA, respectively. One MS thesis has been completed using the support from this project. Another student will finish his thesis within the next couple of months (he was partially funded by the GCHSRC funding). Both will continue their professional development within the field of environmental engineering. The study has also generated six publications. |
RUH766 | Chlorinated Solvent Impact and Remediation Strategies for the Dry Cleaning Industry The findings from our research show that enhanced bioremediation and bioaugmentation may be viable options for decreasing source longevity and potentially overall exposure to chlorinated solvents with shorter plume lengths. This treatment option is also low maintenance and requires minimal equipment when a long-term electron donor such as Hydrogen Release Compound is used in sufficient quantities. Furthermore, our study reassures the public that huge quantities of methane will not be produced nor will there be the need to have the direct injection of hydrogen gas through these techniques and thus preventing potential explosive hazards. Additional funding has been received from the Advanced Technologies Program of the State of Texas by collaborators on this project, Dr. Herb Ward and Dr. Joseph Hughes. This project has produced a MS thesis and two presentations. One manuscript is under preparation for potential publication. |
TAM769 | Soil/Sediment Remediation by Hot Water Extraction Combined with In-Situ Wet Oxidation The goal of this project is to determine the conditions where the combined extraction/oxidation process would be effective. The outcome of this study will provide the fundamental data needed to evaluate the potential for using hot water, with or without combined oxidation, for remediation of contaminated solids at a large scale. The outcome of the project will serve the basis for a new technology which would be a more feasible alternative to current technologies of incineration, thermal desorption, and solvent extraction. |
TAM771 | Fluoracrylate Polymer Supported Ligands as Catalysts for Environmentally Benign Synthesis in Supercritical Fluids The project has already synthesized the polymer with the NASI group replaced by a catalyst precursor and a diazo dye which gives the polymer a red color. It has been shown that these products are soluble in scC02 and dye substituted polymer gives an orange/yellow colored solution. In order to evaluate whether the dye is active, we dissolved the polymer in scC02 in the presence of an organic base, diethylamine. The azo dye, in a basic solution, would have a yellow color, and we have observed that the color does indeed change to yellow from orange/yellow. Hence we have qualitatively shown that the polymer/catalyst is soluble in carbon dioxide and that the functionalized sites are exposed in solution and are available for reaction. |
TAM774 | The Feasibility of Electorphoretic Repair of Impoundment Leaks The objectives of this study were to evaluate the effects of solution chemistry and clay particle properties on the performance of electrophoretic repair of clay liners leaks through modeling and experiment. The project has developed, tested and modelled an in situ technique to repair leaky clay liners. Its final report is available online. The code will also be available online. The project is working on submitting peer-reviewed paper on the research to disseminate our findings. |
MSU777 | Surfactant Enhanced Photo-oxidation of Wastewaters This study was a joint effort between researchers at The University of Alabama and Mississippi State University. The researchers at Alabama were charged with developing an understanding of the mechanisms and kinetics involved with the photo-oxidation of organics dissolved in water. The Mississippi State University researchers were to develop a reactor for continuous treatment of wastewaters based on data obtained at Alabama. Our contribution to the public knowledge was that "the incorporation of the TiO2 into a meso-porous silica matrix is a promising technique for immobilizing the TiO2 in wastewater treatment. This eliminates the need for separation of the TiO2 powder from the wastewater." Three technical presentations of this study have been made at various conferences. |
UAL777 | Surfactant Enhanced Photo-oxidation of Wastewaters It has became apparent that the colloidal nature of the TiO2 particles represented a significant problem, both in data analysis and in successful implementation of a process based on the use of such materials. A further goal of the project became to support the TiO2 particles in a mesoporous matrix which would retain of the photoactivity of the TiO2 particles, while avoiding the need to separate out the TiO2 particles after the photodegradation reaction was complete. Mesoporous matrices were of further interest as the pores were of a scale to exclude other solutes such as humic acids that might be present and could adversely affect the photodegradation of the pollutants. Accomplishments from the work include six publications cited. An outgrowth of the work was a successful NSF travel proposal by the graduate student who worked on the project. |
UAL778 | Stationary Power Generation Via Solid Oxide Fuel Cells: A Response to Pollution and Global Warming The overall objective of the project is to make stationary power generation by SOFCs a major component of the all-methane economy which would (1) reduce C02 emissions by >60% thereby stabilizing the concentration of C02 in the atmosphere (a significant factor in global warming) and (2) provide the United States with an approximate annual savings of $69 billion on its fuel bill. Students working on this project have taken part in a new paradigm in higher education where, regardless of background, scientists and engineers work side-by-side with common goals and more broadly defined interests. |
UCF786 | Photocatalytic Recovery of Sulfur and Hydrogen From Hydrogen Sulfide This project served the public interest by developing technologies whereby the emission of air pollutants from oil refineries, sewage treatment plants, and municipal landfills can be reduced. It also expanded our supply of natural gas by enabling the exploitation of gas wells that were formerly considered to be too sour to be of economic value. It also helped lower the cost of making clean diesel and gasoline by recycling process hydrogen within the petroleum refinery. The project has produced one patent entitled “Closed Cycle Photocatalytic Process for Decomposition of Hydrogen Sulfide to its Constituent Elements,” Clovis A. Linkous and Nazim Z. Muradov, US 6,572,829 B2, June 3, 2003. A potential 2nd patent entitled “UV Photochemical Option for Closed Cycle Decomposition of Hydrogen Sulfide to its Constituent Elements,” is being reviewed. The project has also produced six publications/presentations. |
UHH787 | Biosurfactant Produced from Used Vegetable Oil for Removal of Metals From Wastewaters and Soils The project has concluded that used vegetable oil can be used to produce biosurfactant andthis biosurfactant could be used to remove lead and other metal contaminants from contaminated water and soil. The performance of the biosurfactant was better than other surfactants. Hence used vegetable oil from homes and restaurants can be recycled and used to treat metal contaminated water and soil. The project has generated two publications |
UHH789 | Genetic Engineering of Enzymatic Cyanide Clearance The project has successfully completed all three project objectives including the analysis of the candidate enzymes with respect to their kinetic profiles and their response range to pH, temperature, metal inhibition and stability. This project has produced four publications/presentations. In addition, the project has an ongoing collaboration with a small Houston company, EcoShield, to test the use of our enzyme system to for the cleanup of cyanide contaminated waster water from industrial sites. If effective our process will reduce the costs of waste water cleanup, reduce the danger of shipping such waste water for chemical remediation, and most importantly have resources available for the immediate cleanup of any environmental cyanide spills before significant spreading occurs. |
UHH791 | Characterizing the Intrinsic Remediation of MTBE at Field Sites A database of 127 sites has been assembled for leaking petroleum storage tank (LPST) sites contaminated with MTBE using the Texas Commission of Environmental Quality (TCEQ) site records. A large percentage (61%) of the sites in the database were located along the Gulf Coast. The remaining sites cover most areas across Texas and therefore represent several geologies and lithologies. The 127 sites had mostly shallow groundwater (less than 30-ft (9.1-m) below ground surface) and the impacted water zone was not a drinking water source. The monitoring well networks at the 127 sites consisted of 12 monitoring wells on average but ranged from a minimum of 6 to a maximum of 64 wells. The project has resulted in four peer reviewed publications and numerous presentations and conference proceedings papers. Two students received their master’s degrees as a result of the project funding and are currently employed in the private sector. The project has also helped a post-doctoral researcher re-enter the workforce after a parenting leave. |
UTA799 | Water Conservation/Recycling/Reuse and Waste Reduction in Semiconductor Manufacturing The primary goal of this proposed research is to extend the work with the microchip manufacturing plants to investigate both treatment options and waste reduction options for currently non-recyclable wastestreams to make them recyclable. We believe that several types of wastes fit this description, and that creative and inexpensive treatment and/or minor modification of waste generating processes can be developed to accomplish this goal. The results will lead to a reduction in the use of natural resources, a reduction in the generation of hazardous wastes, and an increase in the economic potential of the region. |
UTA801 | Building Defined Mixed Cultures to Biodegrade Diverse Mixtures of Chlorinated Solvents The goal of this research is to identify a culture of organisms that could degrade TCA with a rate significant enough that a practical hollow fiber membrane bioreactor (HFMB) system could be designed. Batch kinetic experiments performed in this research measured pseudo-first-order rate constants ranging from 0.15 to 1.19 L/mg-day, which was found sufficient to sustain reasonable removal in a bioreactor. The major accomplishment from this project is the education of a Master’s student who is now out in practice working for a consulting engineering firm. This project allowed him to develop expertise with biological treatment systems, which are widely used in practice for hazardous waste treatment. A Master’s thesis has also been produced that characterized the cometabolic degradation kinetics of 1,1,1-trichloroethane by a butane-degrading bacteria. |
UTA802 | Studies of Catalytic Materials Employed in the Hydroprocessing of Halogenated Organics The project has studied the reaction of chlorinated methanes with the clean, oxygen pre-covered, and hydrogen pre-covered Ir(110) and Ir(111) surfaces. In these studies we discovered that most of these chlorinated methanes dissociatively chemisorb readily on both surfaces over a wide temperature range. Further, carbon tetrachloride reacts with adsorbed oxygen and adsorbed hydrogen on the Ir(110) surface and chlorine from the decomposed molecule poisons these surface reactions and additional adsorption. Small amounts of methane are made in the reaction of carbon tetrachloride with the hydrogen pre-covered Ir(110) surface. In addition, the project has also synthesized a planar model catalyst composed of a single crystalline sample of titania (TiO2(110)) decorated with gold nanoclusters and we have begun reaction studies with this sample. The project has generated eleven publications/presentations. |
LUB810 | Application of Total Cost Assessment to Process Design in the Chemical Industry The objective of this project is to demonstrate the incorporation of the spreadsheet version of CWRT's Total Cost Assessment tool with SYNPHONY, combining a new methodology for optimal chemical complex configuration. Further, it would determine the feasibility of incorporating intangible costs with SYNPHONY, a methodology for determining the optimal chemical complex configuration. The societal costs of "harmless odors" have been developed by Beth R. Beloff and Earl R. Beaver as part of the overall CWRT Total Cost Assessment program. Harmless odors have been used as the example for trial incorporation of intangible costs in this project. |
TAM705 | A Pilot Plant for Producing Mixed Ketones from Waste Biomass The pilot plant is nearly completed. The project is still working on it. A major oil company likes this technology and is helping the project build a small demonstration plant. Eventually, the process will be commercialized on a large scale and will produce fuels and chemicals from biomass. This has the following benefits: (1) wastes are eliminated from the environment, (2) biofuels address global warming, (3) less dependency on foreign fuels, (4) cleaner burning fuels, and (5) lower energy prices. Nine patents have been issued related to the project. Many more are pending. |
UCF743 | Field Demonstration of Ultrasound Enhancement of Permeable Treatment Walls - Phase II The results of this project have demonstrated the use of ultrasound to maintain the reactivity of zero-valent iron used in the subsurface to treat contaminated groundwater. As a result of this funding Environmental Technologies acquired the rights to use ultrasound for this purpose. Ultrasound reduces the cost and increases the efficiency of an important groundwater remediation tool, zero-valent iron. The project has received a patent: Quinn, J. W., Ruiz, N. E., Reinhart, D. R., Geiger, C. L., Clausen, C. A., Enhancement of Zero-Valent Metal Treatment of Contaminated Groundwater by the Use of Ultrasound, US Patent No. 6,013,232. The project has also generated fifteen publications. |
UCF807 | Technical Support for Commercialization of Hydrogen Peroxide Injection to Control Nox Emissions from Combustion Sources The project is to provide technical support to help transfer the Hydrogen Peroxide Injection technology to industry faster than would otherwise be possible by marketing efforts from EKA Chemicals alone. Discussions were held with our industrial partner, EKA Chemicals, about travelling with them to meet some potential adopters of the hydrogen peroxide technology. However, EKA has not been able to arrange any visits yet. Along the more traditional lines of technology transfer, Drs. Cooper and Clausen continue to work on technical papers to be submitted for publication in peer-reviewed journals. The project has worked with several industries to inform them of the technology. There was some interest but no adoptions of the technology. More engineers are now aware of this technology. The project has generated five publications. |
UHH809 | Evaluating Source Grouting and ORC for Remediating MTBE Sites The goal of the project is to study the effectiveness of oxygen releasing compounds (ORC) as a source of oxygen when injected in slurry form directly into the soil matrix. In addition to the field injection study, laboratory oxygen release studies were completed to determine the levels of oxygen that can be released from ORC as well as the longevity of ORC as an oxygen source. The project has resulted in four peer reviewed publications and numerous presentations and conference proceedings papers. Three students received their master’s degrees as a result of the project funding and are currently employed in the private sector. The project has also helped a post-doctoral researcher re-enter the workforce after a parenting leave. Technically, the project resulted in simple modeling tools that could be used to design delivery systems for the Oxygen Releasing Compound remediation technology. |
RUH846 | Quantitative Demonstration of Source-Zone Bioremediation in a Field-Scale Experimental Controlled Release System Anaerobic in situ bioremediation of a DNAPL source-zone has been quantitatively demonstrated using a commercially available slow-release electron donor. The presence of chlorinated solvent DNAPLs and their limited dissolution rates have controlled the effectiveness of pump-and-treat systems to date. Reductive dechlorination by subsurface microorganisms under anaerobic conditions has been shown to increase the rate of DNAPL dissolution by a factor of 10 or more. In commercial applications the increased costs will be the costs of hydrogen addition to support reductive dechlorination. The cost savings will be highly site specific, but a reduction in pumping time by half could save millions of dollars at each site. Alternative technologies (e.g., solvents/surfactants, thermal methods) for removal or destruction of DNAPLs are also highly site specific, but range from $300 to $600 per cubic yard of source-zone treated. |
For other GCHSRC activities during the report period, the Environmental Protection Agency conducted a scientific and institutional peer review of the Gulf Coast Hazardous Substance Research Center at Lamar University on April 17-19, 2001. The panel conducted the review with the goal of helping the Center utilize the established strengths currently existing and demonstrated. According to the panel these strengths include: (1) participation of some world class research faculty at several universities; (2) some industrial applications and recognition as evidenced by pilot programs and industry matching funds; (3) at some universities there has been excellent leveraging of the Center’s research funds to secure other funding; and (4) training of graduate students and the Masters and Doctoral levels. Based on the productivity demonstrated by the Center the review panel stated that funding should be continued subject to availability of resources. A Post Award Monitoring Site Review was also conducted by EPA representatives on February 20 and 21, 2002. The purpose of this visit was to review the administrative and financial aspects as outlined under subpart C of CFR 40 Part 30 and 40 and to also monitor the Center’s adherence to the terms and conditions of the award. The results of this review were very positive. An additional recommendation made by the panel was that the Center should make a concerted effort to develop forums for interactions between the Principal Investigators (PIs) on prospective and funded research projects.
Based on the panel recommendation to develop a forum for interaction of PIs the Center reviewed its active projects and selected oxidation/ catalysis as the topic for the initial program. The Center had projects on oxidation/catalysis at eight of the nine affiliated universities. On August 1, 2001 PIs from the eight universities met at Lamar University to discuss their research projects and exchange data and ideas for ongoing and future work on this technology.
During the report period the Center revised the Quality Assurance Management Plan that was approved by the National Center for Environmental Research and Quality Assurance in 1997 to create a Quality Management Plan (QMP). The goal of this QMP is to assure that data collected for the characterization of environmental processes and conditions are of the appropriate type and quality for their intended use and that environmental technologies are designed, constructed, and operated according to defined expectations. It is the policy of the Gulf Coast Hazardous Substance Research Center to implement and fully support accepted standards for practicing quality assurance and quality control in all research conducted under its auspices. The Center follows guidance provided by the Office of Information’s Quality Staff. The United States Environmental Protection Agency Project Officer approved the most updated version of QMP in January 2003.
An annual site visit was made to each member university to monitor research projects and conduct laboratory inspections as required by the Center’s Policy Manual to the Grants Administration Division. During the site visit the principal investigator or graduate students working on the project made presentations and updated the status of the research effort. In addition quality assurance audits were conducted on selected projects to assure compliance with the approved quality assurance project plans. The audits also involved laboratory inspections for health and safety related issues.
The Center conducted an Industrial Needs Workshop (INW) during the Agreement period. The topic area of the workshop was Treatment of Chlorinated Solvents, MTBE, Perchlorates, and TNT. The workshop was held on September 22, 2000. The details of the workshop are provided at the Center homepage at http://dept.lamar.edu/gchsrc/ under the Workshops link. In addition to access to all sponsored projects (with abstracts and publications) the homepage has links to other Hazardous Substance Research Centers and related environmental sites. Center newsletters, important dates, workshops, member universities, science advisory council, principal investigators, and staff are available under appropriate tabs. The Center receives numerous requests to make presentations on the research program from local and state environmental organizations as well as the media. Presentations to environmental managers from local industries and community action panels are typical examples. We also participated in technology development forums organized by our Representative Congressman Nick Lampson. The Center provides technical advice to citizen inquires on a wide range of environmental issues.
In summary, the Center has successfully accomplished its mission and fulfilled its obligations under this Assistance Agreement R-828598-01 with the US EPA during the Agreement period from September 1, 2000 through August 31, 2004. The Center was awarded $4,749,800 on this grant. We spent $4,735,478 conducting and supporting 38 research projects over the four-year grant period. The Center also supplied an additional $1,813,661 of matching funds.
