Title: Innovative and effective landfill treatment

Abstract

An innovative and effective metals treatment technology was developed for a Superfund site landfill. The new landfill technology reduced the remedial cost of that operable unit from $34 million (MM) to $12 MM. In 1993, EPA issued a Record of Decision (ROD) for a Superfund site in Newport, Delaware. Among other remedies, deep-soil mixing was specified for a 16-acre landfill. New information on waste volumes developed in the remedial design phase increased the cost of the remedy from $14 MM to $34 MM. An alternative treatment technology was developed to immobilize the metal contaminants with no increase in volume. EPA was included early in the development to ensure the proposal would be focused on issues critical to its review and acceptance. EPA accepted this technology and issued an Explanation of Significant Differences decision. the new remedy is estimated to cost $12 MM. The constituents of concern at the site are primarily metals: barium, lead, zinc, and cadmium. A treatment technology was developed which employed straight-forward chemical precipitation: sulfate addition for barium and sulfide addition for lead, zinc, and cadmium. The combined effect of numerous competing chemical equilibrium effects was modeled with the Environmental Simulation Program (ESP), a state-of-the-art equilibrium simulationmore » program from OLI Systems, Inc. Due to the potential effects of acid rain, limestone was added to the treatment plan.« less

  • Pursuant to a settlement agreement reached between the US Department of Energy (DOE) and the South Carolina Department of Health and Environmental Control (SCDHEC), the Sanitary Landfill at the Savannah River Site will be closed. This paper addresses the approach used to select the innovative in situ treatment alternative for the groundwater and the vadose zone associated with the landfill.
  • The innovative use of poplar trees at landfills to improve final closure cover caps and to treat and monitor leachate and stormwater runoff offers significant cost and management advantages. This paper describes the basic concepts for using poplar tree technologies and compares the poplar tree systems to the prevalent, conventional approaches, such as the synthetic membrane cover cap and land application of leachate on grass crops. The paper also discusses where the poplar tree systems are feasible, the main elements of their implementation, and the potential cost savings that can be realized.
  • The Chemical Waste Landfill (CWL) was used by Sandia National Laboratories (SNL), Albuquerque for disposal of hazardous chemicals from the years 1962 to 1985. Prompted by the detection of low levels of trichlorethylene (TCE) in groundwater samples from a water table aquifer approximately 146 meters below ground surface, a RCRA Site Investigation (RSI) and remediation of organic contaminants will be performed at the CWL prior to closure of this landfill. The RSI is focused on optimal characterization of the VOC and dense non-aqueous phase liquid (DNAPL) contamination at this site which will be possible through application of innovative strategies formore » characterization and promising new technologies. This paper provides a discussion of conceptual models of contaminant transport at the CWL, and an overview of our investigative strategy which is focused on characterizing transport of VOC and DNAPLS. Each stage of the RSI has been developed to gather information which will reduce the uncertainty in the design of each subsequent phase of the investigation. Three stages are described; a source characterization stage, unsaturated zone characterization stage, and a saturated zone characterization stage. The unsaturated zone characterization must provide all data necessary to make decisions concerning the necessity of a saturated zone characterization phase.« less

  • The Savannah River Site Sanitary Landfill is an approximate 70-acre site. In 1974, it was a 32-acre site receiving solid waste from a variety of sources. In 1987, the original area reached its capacity and a 16-acre northern expansion and a 22-acre southern expansion were added. The southern expansion is nearing capacity, and the northern expansion opened in 1993. During its operation, the Sanitary Landfill received rags and wipes used with F-listed solvents. In 1988, the Sanitary Landfill became the subject of a RCRA facility investigation and was designated a RCRA solid waste management unit because of recurring evidence ofmore » RCRA hazardous constituents in the groundwater. DOE and SCDHEC reached a settlement agreement, outlining the steps DOE would take to comply with RCRA regulations. Principally, DOE would close the portions of the, landfill containing the solvent rags. This paper describes the technology selection process conducted for the SRS Sanitary Landfill site and the innovative in situ treatment alternative selected for the groundwater and the vadose zone associated with the landfill.« less
