Abstract
Coal tar, a dense nonaqueous phase liquid (NAPL), is a common subsurface contaminant at sites of former manufactured gas plants. A proposed remediation technology is water-miscible solvent extraction, which requires understanding of the effect of water-miscible solvents on the solubility of coal tar. This study investigated this effect and the extent to which multicomponent coal tar could be represented as a pseudocomponent in thermodynamic modeling. The coal tar used in this study showed a predominance of polycyclic aromatic hydrocarbons nvith no single compound accounting for more than 4% (nvt). The bulk solubility of coal tar in water was estimated to be 16 mg/L using composition data and Raoult's law assumption for aqueous solubility
