Title: Soil gas investigations at the Sanitary Landfill

Abstract

A soil gas survey was performed at the 740-G Sanitary Landfill of Savannah River Plant during December, 1990. The survey monitored the presence and distribution of the C[sub 1]C[sub 4] hydrocarbons; the C[sub 5]-C[sub 10] normal paraffins; the aromatic hydrocarbons, BTXE; selected chlorinated hydrocarbons; and mercury. Significant levels of several of these contaminants were found associated with the burial site. In the northern area of the Landfill, methane concentrations ranged up to 63% of the soil gas and were consistently high on the western side of the access road. To the east of the access road in the northern and southern area high concentrations of methane were encountered but were not consistently high. Methane, the species found in highest concentration in the landfill, was generated in the landfill as the result of biological oxidation of cellulose and other organics to carbon dioxide followed by reduction of the carbon dioxide to methane. Distributions of other species are the result of burials in the landfill of solvents or other materials.

  • A soil gas survey was performed at the 740-G Sanitary Landfill of Savannah River Plant during December, 1990. The survey monitored the presence and distribution of the C{sub 1}C{sub 4} hydrocarbons; the C{sub 5}-C{sub 10} normal paraffins; the aromatic hydrocarbons, BTXE; selected chlorinated hydrocarbons; and mercury. Significant levels of several of these contaminants were found associated with the burial site. In the northern area of the Landfill, methane concentrations ranged up to 63% of the soil gas and were consistently high on the western side of the access road. To the east of the access road in the northern andmore » southern area high concentrations of methane were encountered but were not consistently high. Methane, the species found in highest concentration in the landfill, was generated in the landfill as the result of biological oxidation of cellulose and other organics to carbon dioxide followed by reduction of the carbon dioxide to methane.

  • A series of preliminary helium soil gas surveys at a landfill site in DuPage County, Illinois, were conducted as part of a larger program to investigate the influence of meteorological parameters and, eventually, gas recovery operations on the production, transport, and migration of gases at landfill sites. The first survey determined the overall distribution of helium at the landfill and served as a guide to establish fixed stations for later surveys. The second survey monitored the variation of helium concentrations with time to view the effect of meteorological influences. From the helium data higher concentrations of landfill-produced gases were inferredmore » to be located near the flanks of the landfill. The surface manifestations of gas were very localized, occurring in discrete areas of 100 m/sup 2/ or less. Fracture systems, developed by the settling landfill, control the near surface release of the gas and increase the local permeability permitting greater atmospheric dilution of the soil gases than at other areas of the landfill. 5 refs., 2 figs., 3 tabs.« less
  • A summary is presented of the results of sampling and analysis of ambient and process gas streams, and liquid and solid samples taken at different locations from the Pacific Gas and Electric Company Landfill Gas Recovery Plant in Mountain View, California. The purpose of this study is to identify environmental pollutants and characterize the trace chemistry of landfill gas recovered from the Mountain View Sanitary (Class II) Landfill. Gaseous samples, liquid condensate, and other plant products were analyzed for their trace chemical constituents, and the results indicate that certain organic and inorganic pollutants inherent to the landfill are emitted intomore » the ambient environment and also become involved in the methane recovery process. Incorporation of condensate traps, molecular sieve, and charcoal filtration was found to significantly reduce both the organic and inorganic component burdens in the product gas. The environmental significances of the landfill gas recovery to the surrounding area and to worker safety are presented.« less
