Preliminary characterization of the F-Area Railroad Crosstie Pile at the Savannah River Site

Description: Historical information about the F-Area Railroad Crosstie Pile is limited. The unit is believed to have been a borrow area for earth fill that began receiving railroad crossties during the 1960s. The number of crossties at the unit began to increase significantly in 1984 when major repair of the SRS rail system was initiated. An estimated 100,000 used railroad crossties have accumulated at the unit since 1984. In an effort to determine the impact of the railroad crossties on the environment a t… more

Antifouling marine concrete

Description: Various toxic agents were evaluated as the their capability to prevent or inhibit the attachment of marine fouling organisms to concrete. Creosote and bis-(tri-n-butyltin) oxide (TBTO) were impregnated into porous aggregate which was used in making concrete. Cuprous oxide, triphenyltin hydroxide (TPTH), and 2-2-bis-(p-methoxyphenyl)-1,1,1-trichloroethane (methoxychlor) were used as dry additives. Two proprietary formulations were applied as coatings on untreated concrete. Test specimens were ex… more

PLUTONIUM UPTAKE AND BEHAVIOR IN PLANTS OF THE DESERT SOUTHWEST: A PRELIMINARY ASSESSMENT

Description: Eight species of desert vegetation and associated soils were collected from the Nevada National Security Site (N2S2) and analyzed for 238Pu and 239+240Pu concentrations. Amongst the plant species sampled were: atmospheric elemental accumulators (moss and lichen), the very slow growing, long-lived creosote bush and the rapidly growing, short-lived cheatgrass brome. The diversity of growth strategies provided insight into the geochemical behavior and bio-availability of Pu at the N2S2. The highes… more

Bell Pole CROW pilot test results and evaluation

Description: Beginning in 1990, efforts were initiated to implement an in situ remediation project to address the creosote and pentachlorophenol (PCP) contaminated surficial aquifer at the Bell Lumber and Pole Company (Bell Pole) Site. The remediation project involves the application of the Contained Recovery of Oily Wastes (CROW[trademark]) process which consists of hot-water injection to displace and recover the non-aqueous phase liquids (NAPL). Based on the results from the pilot test the following concl… more

Use of bioassays in assessing health hazards from complex mixtures: A RASH analysis

Description: The Finney harmonic mean model for joint toxicity of ingredients in mixtures can be used to estimate the toxicity of the neat compound if one component can be substituted in potency-adjusted-doses for each of the other components. Chemical analysis data and relative potency values (computed according to the Rapid Screening of Hazard (RASH) method) were used to compare the toxicities as predicted from ingredients of cigarette smoke, PAHs in diesel exhaust, asphalt, coal tar, pitch, and creosote … more

Material Property Estimation for Direct Detections of DNAPL using Integrated Ground-Penetrating Radar Velocity, Imaging and Attribute Analysis

Description: The focus of our work is direct detection of DNAPLs, specifically chlorinated solvents, via material property estimation from surface ground-penetrating radar (GPR) data. We combine sophisticated GPR processing methodology with quantitative attribute analysis and material property estimation to determine the location and extent of residual and/or pooled DNAPL in both the vadose and saturated zones. An important byproduct of our research is state-of-the-art imaging which allows us to pinpoint at… more

Studies in Coal Liquefaction With Application to the SRC and Related Processes. Quarterly Report, November 1981-January 1982

Description: The concentration of hydroaromatics in a coal liquefaction solvent is regarded as a significant factor in the determination of solvent quality. An analytical method is described based on catalytic solvent dehydrogenation (CSD) for the measurement of transferable hydrogen, including hydroaromatic sources, in a solvent. The dehydrogenation of several model compounds in the presence of Pd/CaCO/sub 3/ was conducted under batch conditions. Hydroaromatics containing six-member rings were found to deh… more

Effects on liquefaction of recycling heavy SRC. SRC-I quarterly technical report. Supplement July-September 1980

Description: To avoid the possibility of solvent shortages in the Demonstration Plant, studies are continuing to determine if recycling SRC will generate an increased yield of recycle solvent and maintain adequate solvent quality for the design plant. We hope also to determine if major operational problems may develop with SRC recycle. The present study used processing mixtures of Kentucky No. 9 coal, solvent, and heavy solvent-refined coal (HSRC). To ascertain the effects of HSRC on coal liquefaction, proc… more

Organic and inorganic hazardous waste stabilization utilizing fossil fuel combustion waste materials

Description: A laboratory study was conducted at the Western Research Institute to evaluate the ability of innovative clean coal technology (ICCT) waste to stabilize organic and inorganic constituents of hazardous wastes. The four ICCT wastes used in this study were: (1) the Tennessee Valley Authority (TVA) atmospheric fluidized bed combustor (AFBC) waste, (2) the TVA spray dryer waste, (3) the Laramie River Station spray dryer waste, and (4) the Colorado-Ute AFBC waste. Four types of hazardous waste stream… more

In situ hydrothermal oxidative destruction of DNAPLS in a creosote contaminated site

Description: Hydrous Pyrolysis / Oxidation (HPO) is an in situ thermal remediation technology that uses hot, oxygenated groundwater to completely mineralize a wide range of organic pollutants. A field demonstration of HPO was performed at a creosote contaminated site during the summer of 1997. The groundwater was heated by steam injections and oxygen was added by coinjection of compressed air. The remediation was monitored from multiple groundwater monitoring wells. Dissolved organic carbon levels increased… more

TECHNOLOGY MATURATION OF DISPERSION TECHNOLOGY TO AUGMENT BIOREMEDIATION

Description: The data obtained from this preliminary short-term project demonstrated that dispersants such as 54GO are effective in accelerating the bio-remediation of soils containing contamination from waste oils, diesel, creosote and manufactured gas plant waste. This acceleration appears to be in the observation that 54GO quickly separates the hydrocarbon wastes from the soil particles, thereby allowing closer contact with the microbes. The project time limitations impacted the scope of data but was abl… more

Research investigations in oil shale, tar sand, coal research, advanced exploratory process technology, and advanced fuels research: Volume 2 -- Jointly sponsored research program. Final report, October 1986--September 1993

Description: Numerous studies have been conducted in five principal areas: oil shale, tar sand, underground coal gasification, advanced process technology, and advanced fuels research. In subsequent years, underground coal gasification was broadened to be coal research, under which several research activities were conducted that related to coal processing. The most significant change occurred in 1989 when the agreement was redefined as a Base Program and a Jointly Sponsored Research Program (JSRP). Investig… more

Semivolatile organic (GC-MS) and inorganic analyses of groundwater samples during the hydrous pyrolysis/oxidation (HPO) field test in Visalia, CA, 1997

Description: Hydrous pyrolysis/oxidation (HPO) is a novel, in situ, thermal-remediation technology that uses hot, oxygenated groundwater to completely oxidize a wide range of organic pollutants. A field demonstration of HPO was performed during the summer of 1997 at the Southern California Edison Pole Yard in Visalia, California, a site contaminated with creosote. The goal of the field experiment was to confirm the success of HPO under field remediation conditions. The groundwater was heated by steam inject… more
