A finite-difference algorithm used to simulate radial diffusion, adsorption, and reactions of chlorinated ethenes in porous media

Simulations of radial diffusion, adsorption, and reactions of volatile organic compounds (VOCs) - trichloroethene (TCE), cis-1,2-dichloroethene (cDCE), vinyl chloride (VC), trichlorofluoroethene (TCFE) - and bromide (Br) in a porous media are conducted using rock properties identified from a mudstone aquifer in the Newark Basin, near West Trenton, New Jersey. The simulations are conducted using a finite-difference algorithm that was prepared for this investigation to solve the equation for radial diffusion, linear equilibrium adsorption, and zero- and first-order biodegradation. The simulations are conducted for a section of a rock matrix and the georeferencing is based on the locations of the well from which concentration data were [...]
