Abstract
Dense Non Aqueous Phase Liquids (DNAPLs) are a family of fluids often encountered as industrial contaminants. Some of
the most problematic DNAPLs are chlorinated solvents such as trichloroethylene (TCE) and tetrachloroethylene (PCE). While
many DNAPLs have been extensively studied from a hydrology perspective, documentation of DNAPL properties relevant to
geophysical detection is far from complete. We present a short survey of acoustic velocity, density, and dielectric constant
measurements for an important subset of commonly encountered dense chlorinated contaminants. Viscosity and surface tension
data are included to allow exploration of contaminant signatures within the context of poroelastic or contact theory models.
Where available, the temperature dependence of solvent properties are also provided. Densities for the listed DNAPLs range
from 1253 to 1622 kg/m3
