Vapor2D was modified to predict the migration of gasoline vapors from a subsurface spill area, and includes a multicomponent NAPL source model. Vapor2D was successfully validated by simulating laboratory experiments of vapor flow and transport of heptane in the vadose zone, and Vapor2D has been used to assess density‑dependent landfill gas, chlorinated solvent vapor ...

Following a comprehensive spectroscopic study of coal tar behavior, Dakota created this method which results in a monotonic response for coal tars on a variety of soils. Lab tests of TarGOST indicate the system is ideally suited for delineating the NAPL contaminated zones or source term at former manufactured gas plants (MGPs) and wood treating facilities. ...

Spatial analyses in the fields of urban and regional planning, transport planning, environment, climate or geology often require high resolution socio-economic data. Such analyses work with raster data to calculate indicators such as exposure to air pollutants or to noise. In many cases available socio-economic data do not have the necessary spatial resolution. Usually, data on population, ...

The Matrix Diffusion Toolkit, developed for the Department of Defense ESTCP program, is an easy-to-use, comprehensive, free software tool that can assist site personnel to effectively and efficiently estimate what effects matrix diffusion will have at their site, and transfer the results to stakeholders. The Toolkit provides the following tools to calculate and evaluate matrix diffusion ...

The mass balance paradigm is an important new approach to evaluating Monitored Natural Attenuation (MNA) at chlorinated solvent sites. By using the mass balance approach, site managers can demonstrate that the assimilative capacity of a particular system is either capable (or incapable) of managing the mass flux of chlorinated solvents emitted from a source zone. In addition, a detailed mass ...

Historically, environmental consultants, geophysicists, and academics that have tried using conventional electrical resistivity imaging (ERI) technology and/or other geophysical methods to image contaminant plumes have been largely dissatisfied with the results. Our early experiments with standard electrical resistivity imaging and other technologies also yielded unsatisfactory results. The ...
