Effect of groundwater flow on remediation of dissolved ...

2000-2-25  Dissolved-phase benzene removal due to vapor-phase partitioning did not, however, account for total removal of benzene mass within the initial contaminant zone. Advective–dispersive transport induced by groundwater flow resulted in lateral benzene migration. In regions of high groundwater flow, advective transport controls mass transfer.

Field Investigation of Vapor-Phase-Based Groundwater ...

Vapor-phase-based groundwater monitoring relies on the equilibrium partitioning process for dissolved volatile organic compounds (VOCs) in contact with a gas phase (e.g., Sanford et al. 1996 ...

Fate of Spilled Perc in the Subsurface: Understanding the ...

A basic investigation into groundwater flow determines two important characteristics: direction and velocity. A dissolved phase PCE plume will travel in the direction of groundwater flow. Groundwater, more than any other mechanism, is the likely culprit for PCE leaving a drycleaner spill site and onto a neighboring property.

2014-10-29  The purpose of this study is to examine the development and effectiveness of a persistent dissolved-phase treatment zone, created by injecting potassium permanganate solution, for mitigating discharge of contaminant from a source zone located in a relatively deep, low-permeability formation. A localized 1,1-dichloroethene (DCE) source zone comprising dissolved- and sorbed-phase mass is

2021-7-20  Because free-phase gases are typically a mixture, and most groundwater naturally contains one or more dissolved-phase gases, the solubility of the components of natural gas (methane, ethane) will be less than that estimated for pure methane or ethane solubility alone (Cahill et al., 2018; Forde et al., 2019b; Van De Ven and Mumford, 2020a ...

2021-4-28  Phosphorus (P) loss/retention at the landscape scale is highly complex and is influenced by overland and subsurface flows of many different organic and inorganic species. Estimation of P loss often focuses on the dissolved phase and does not consider colloidal particles, which are a vector by which contaminants and nutrients can be transported long distances.
