“…For example, although benzene is a known human carcinogen (32), it is typically biodegradable (33) and is often amenable to conventional and less costly treatment technologies, such as air sparging, soil vapor extraction (34), and nat-ural attenuation. However, some herbicides, pesticides, and PCBs are typically more persistent and resistant to biodegradation and therefore usually require more costly remedial approaches.…”

Cleanup Costs at WASTE Sites Most people agree that Superfund sites and other complex, multiparty, hazardous waste sites that pose risks to human health and the environment should be remediated. However, the process of apportioning cleanup costs is often disputed among the potentially responsible parties (PRPs). As the available state and federal funding for site cleanup has diminished, pressure has increased for PRP-funded cleanups. Allocating uncertain cleanup costs in a timely, equitable, and mutually acceptable manner among numerous PRPs with different connections to the site, especially given varying legal interpretations and limited data, creates a difficult dilemma. Costly and protracted litigation to determine cost shares is an increasingly unattractive option and provides a strong incentive for devising a fair, understandable, and efficient privately administered approach to allocating costs among PRPs. This article outlines such an approach.Apportioning costs among potentially responsible parties is complicated but can be done with allocation formulas.

“…Obviously, the total available capacity will ultimately depend on the volume of soil or aquifer encountered by a plume on the path from source to receptor. More involved analysis and calculations of electron budgets are outlined in Wiedemeier et al (1995b) 3 gives a simplified view of the breakdown pathways that affect chlorinated organics, such as PCE, TCE, DCE, TCA (trichlorethane), carbon tetrachloride (CT), PCA (tetrachloroethane), VC, and DCA (dichloroethane) in soils and groundwaters. Chlorinated organics are common contaminants in soils and groundwaters and are often the most mobile fraction that dissolves off the fringes of dense nonaqueous phase liquids (DNAPLs).…”

“…The most comprehensive cleanup protocol that includes consideration of natural attenuation is that of Wiedemeier et al (1995b) for the cleanup of fuel hydrocarbons at Department of Defense (DOD) facilities. Natural attenuation is considered as a potential remedy at the very first step of the process, and many of the most critical decision points rely on a conceptual understanding of contaminant degradation in the subsurface.…”

Dissolution Rate of BTEX Contaminants in Water

2005

View full text Add to dashboard Cite

The BTEX group of contaminants consists of benzene, ethylbenzene, toluene, and three isomers of xylene. The dissolution rate, solubility, slick area and mass transfer coefficient were examined for the BTEX. The release of BTEXs into the environment is influenced by their fate and transport mechanisms. Thus, the fate and transport mechanisms are affected by the contaminant characteristics, which vary with the different BTEX compounds. A comprehensive model has been developed to simulate the molecular dissolution rate of BTEX contaminants in a natural water stream. The developed model modifies the work of Cohen et al. (1980) by considering the physicochemical properties of the BTEX compounds and physical processes relevant to the spreading of contaminants in the sea. The model shows that Benzene with greater solubility in water and dissolution coefficient has the largest dissolution rate while o‐xylene with the biggest density has the lowest dissolution rate because of its low fraction. The benzene dissolution rate is about 2.6, 20.6 times that of Toluene, ethylbenzene, respectively, but with a varying proportion with the xylenes. The model has been validated against the theories of mass transfer rate at the surface at appropriate surface area. The developed model can be found useful in prediction and monitoring the dissolution rate of contaminants in soil and water systems.
