Correct implementation of the Argonne Expedited Site Characterization (ESC) process for preremedial site investigations.

Description: The Argonne Expedited Site Characterization (ANL ESC) methodology, developed by Argonne National Laboratory and popularly known as ESC, is an effective, cost- and time-saving approach for technically successful preremedial site characterizations. The major objective of the ANL ESC is to determine whether a site containing contamination requires remediation. The methodology is equivalent to a CERCLA RI/FS or a RCRA RFI/CMS investigation. The ANL ESC methodology is an interactive, integrated proc… more

Fluxes of methane between landfills and the atmosphere: Natural and engineered controls

Description: Field measurement of landfill methane emissions indicates natural variability spanning more than 2 seven orders of magnitude, from approximately 0.0004 to more than 4000 g m{sub -2} day{sup -1}. This wide range reflects net emissions resulting from production (methanogenesis), consumption (methanotrophic oxidation), and gaseous transport processes. The determination of an {open_quotes}average{close_quotes} emission rate for a given field site requires sampling designs and statistical techniques… more

Emissions of Nonmethane Organic Compounds at an Illinois (USA) Landfill: Preliminary Field Measurements

Description: Current US regulatory models for estimating emissions of nonmethane organic compounds (NMOCs) from municipal solid waste (MSW) landfills require field validation to determine if the models are realistic. A project was initiated to begin to develop a field method for direct measurement of landfill NMOC emissions and, concurrently, develop improved sampling and analysis methods for individual NMOCs in landfill gas matrices. Two contrasting field sites at the Greene Valley Landfill, DuPage County,… more

Organic carbon cycling in landfills: Model for a continuum approach

Description: Organic carbon cycling in landfills can be addressed through a continuum model where the end-points are conventional anaerobic digestion of organic waste (short-term analogue) and geologic burial of organic material (long-term analogue). Major variables influencing status include moisture state, temperature, organic carbon loading, nutrient status, and isolation from the surrounding environment. Bioreactor landfills which are engineered for rapid decomposition approach (but cannot fully attain)… more

A comprehensive approach to solid waste and recycling at Sandia National Laboratories

Description: The abrupt closure of a nearby, and historically utilized, Kirtland Air Force Base landfill imposed a multitude of solid waste management problems for the Sandia National Laboratories/New Mexico (SNL) research and development facilities operated by Lockheed Martin Company. Due to the close proximity of KAFB, SNL historically used KAFB`s landfill for disposal of solid waste. Under this arrangement SNL paid little or no cost for disposal of its solid waste stream. The disadvantage was that KAFB p… more

TDR calibration for the alternative landfill cover demonstration (ALCD)

Description: The Alternative Landfill Cover Demonstration is a large scale field test that compares the performance of various landfill cover designs in dry environments. An important component of the comparison is the change in the moisture content of the soils throughout the different cover test plots. Time Domain Reflectometry (TDR) is the primary method for the measurement of the volumetric moisture content. Each of the covers is composed of layers of varying types and densities of soils. The probes are… more
