Summary

Simulations of one-dimensional (1-D) diffusion and adsorption of trichloroethene (TCE) in a rock matrix 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 1-D diffusion and linear equilibrium adsorption. The simulations are conducted for a hypothesized 1-D section of a rock matrix and the georeferencing is based on the locations of the rock core samples that were collected and analyzed as part of this investigation. The rock matrix is assumed to be adjacent to a fracture, where the TCE concentration in the fracture is responsible [...]

Purpose

The simulations were conducted to investigate the effect of the spatial variability of foc on the retention and release of TCE in a rock matrix. Simulations using spatially variable and spatially uniform foc are conducted to compare the effect of spatial variability in foc on the longevity of TCE remaining in the rock matrix. The development of the model input and output files included in this data release are documented in the article published in the Journal of Contaminant Hydrology (https://doi.org/10.1016/j.jconhyd.2018.09.001).
