Hydraulic/partitioning tracer tomography for characterization of dense nonaqueous phase liquid source zones
[1] A new technology, hydraulic/partitioning tracer tomography (HPTT), is proposed to survey spatial distributions of hydraulic properties and dense nonaqueous phase liquids (DNAPLs) in the subsurface. HPTT is nothing more than a set of multiple hydraulic/ partitioning tracer tests and synthesis of all the tests to map the spatial distributions. It involves injection of water at one borehole in...
متن کاملIntermediate - Scale Investigation of Nonaqueous - Phase Liquid Architecture on Partitioning Tracer Test Performance
725 Chlorinated solvents in the form of DNAPLs exist at a large number of hazardous waste sites. The distribution of DNAPLs is controlled by fi ngering (Held and Illangasekare, 1995), preferential channeling, and heterogeneity of the subsurface formation (Kueper and Frind, 1991). All of these factors increase the complexity of NAPL movement and subsequent entrapment (Schwille, 1988; Kueper et a...
متن کاملA method of estimating multicomponent nonaqueous-phase liquid mass in porous media using aqueous concentration ratios.
A simple dissolution model based on Raoult's Law was used to derive a log-linear equation for the estimation of multicomponent nonaqueous-phase liquid (NAPL) mass in porous media. The analysis, referred to here as the ratio mass estimation (RME) method, requires aqueous concentration ratios for two components of the NAPL mixture as well as their pure phase liquid solubilities. Application of th...

متن کاملPush-pull partitioning tracer tests using radon-222 to quantify non-aqueous phase liquid contamination.
Naturally occurring radon in groundwater can be used as an in situ partitioning tracer for locating and quantifying non-aqueous phase liquid (NAPL) contamination in the subsurface. When combined with the single-well, push-pull test, this methodology has the potential to provide a low-cost alternative to inter-well partitioning tracer tests. During a push-pull test, a known volume of test soluti...
