Download or read book FATE AND DISPOSITION OF TRICHLOROETHYLENE IN SURFACE SOILS. written by Thomas Joseph Walker and published by . This book was released on 1984 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trichloroethylene (TCE) is a widely detected contaminant in groundwater. This study investigated fate of TCE in two similar soils with differing organic carbon contents. TCE was applied to soil columns in one 5 or 10 m1 quantity, then eluted with 50 or 100 m1 of water/day. The 1.4% organic carbon soil retarded TCE elution more than did the 0.53% soil. Biodegradation of TCE in the soils, based on effluent TCE and chlorides, was not enhanced by addition of ammonia. Warburg studies showed TCE inhibited biological activity in unacclimated soil. Acclimated soil of both types from 2.5 and 15 inch depths showed degradation of TCE at 55 mg/1 but not 110 or 550 mg/1. No evidence of cis or trans-1,2-dichloroethylene was found in column effluents. Degradation (biological and abiotic) accounted for 0.3% or less of TCE. Volatilization accounted for 15.6-32.8% of TCE applied.

This book was released on 1992 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to collect data that would provide a foundation for the concept of using vegetation to enhance in situ bioremediation of contaminated surface soils. Soil and vegetation (Lespedeza cuneata, Paspalum notatum, Pinus taeda, and Solidago sp.) samples from the Miscellaneous Chemicals Basin (MCB) at the Savannah River Site were used in tests to identify critical plant and microbiological variables affecting the fate of trichloroethylene (TCE) in the root zone. Microbiological assays including phospholipid acid analyses, and 14C-acetate incorporation were conducted to elucidate differences in rhizosphere and nonvegetated soil microbial communities from the MCB. The microbial activity, biomass, and degradation of TCE in rhizosphere soils were significantly greater than corresponding nonvegetated soils. Vegetation had a positive effect on microbial degradation of 14C-TCE in whole-plant experiments. Soils from the MCB containing Lespedeza cuneata, Pinus taeda, and Glycine max mineralized greater than 25% of the 14C- TCE added compared with less than 20% in nonvegetated soils. Collectively, these results provide evidence for the positive role of vegetation in enhancing biodegradation.

Available in PDF, EPUB and Kindle. Book excerpt: Novel recombinant TCE-degrading bacteria were created using the best known enzyme for TCE degradation, soluble methane monooxygenase(sMMO) of the soil bacterium Methylosinus trichosporium OB3b. sMMO degrades a wide range of halogenated hydrocarbons (HCFCs, chloroform, dichloroethane, etc.), and it degrades TCE 100 times faster than any other microbial enzyme. The mmo genes were cloned and expressed in Pseudomonas putida Fl, Agrobacterium tumefaciens, and Rhizobium meliloti using plasmids pSMMO20 and pSMMO40 created by the Wood laboratory. In addition, a novel fixed-film bioreactor has been constructed and optimized to mineralize TCE in the gas phase.

Download or read book Trichloroethylene Contaminated Soil Clean-up Using Surfactant-based Separation Technology and Bioremediation written by Sasikarn Chuahom and published by . This book was released on 2006 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surfactant-based separation technology and bioremediation was integrated to enhance the removal of trichloroethylene (TCE) from soil. In this system, cloud point extraction by non-ionic surfactant was conducted to separate high amount of TCE into the surfactant-rich phase and then bioremediation was integrated into the system by adding bacteria to co-metabolize the remaining TCE. Six surfactant systems including SURFONIC TDA-5, SURFONIC TDA-6, SURFONIC L24-7, NEODOL 91-5, NEODOL 91-6 without electrolyte addition and DTAB/DOWFAX (2:1 molar ratio) with 0.8 M NaCI were studied. These surfactants induced a phase separation with the surfactant-rich phase presented on top of the solution thus preventing the accumulation of surfactant on soil particles. The results found that SURFONIC TDA-6, SURFONIC L24-7, an NEODOL 91-6 did not inhibit TCE degradability of either Rhodococcus sp. L4 or Phodococcus sp. P3 bacteria while others killed the bacteria. Rhodococcus sp. L4 degraded TCE effectively in the presence of SURFONIC TDA-6, in which more than 58% of 10 ppm TCE was reduced within 24 hours compared to only 30% of TCE removal in control treatment (without the bacteria), SURFONIC TDA-6 was then selected for determining the optimal condition for TCE extraction consisting of equilibrium time, contact time between surfactant solution and soil and initial concentration of surfactant. The optimal condition for TCE extraction by cloud point technique were as followed; 72 hours of equilibrium time, 1 lour of contact time between soil and surfactant solution, and 70 mM of initial concentration of surfactant. These acquired conditions were later applied to compare the effectiveness of three TCE treatment processes including: (1) bioremediation, (2) surfactant extraction and (3) integrated technique. TCE removal efficiency was determined from the remaining TCE concentration in soil after treatment. The TCE removal efficiency of 100 ppm TCE contaminated soil by bioremediation, surfactant extraction and integrated technique were about 74%, 74% and 94%, respectively. Morever, TCE was mineralized as showed by the increase of chloride ions after remediation by bioremediation and integrated technique. When increased the amount of initial TCE to 300 ppm, the removal efficiency of the integrated technique was about 94% which was around 30% higher than either technique alone. The result found that soil remediation by the integrated technique had the highest TCE removal efficiency.
