reactive transport models used to simulate the transport of hydrocarbons. The authors hope …

Leakage and spill of petroleum hydrocarbons from underground storage tanks and pipelines
have posed significant threats to groundwater resources across many petroleum …

Introduction Electromagnetic methods have a special place in the arsenal of geophysical
tools available for environmental investigations. They owe their status to five factors. First …

In situ air sparging (IAS) is a technology commonly used for treatment of submerged source
zones and dissolved groundwater plumes. The acceptance of IAS by regulatory agencies …

In situ air sparging has emerged as a popular remedial alternative to traditional pump‐and‐
treat for the remediation of volatile organic contaminants in saturated soils and ground …

A review of published mathematical models used to simulate air sparging is provided.
Applicability of the models, efforts to test the models using experimental data and …

The removal of volatile organic compounds from groundwater by air sparging (AS) is well-
established, although reliable methods for predicting the time required to reach site closure …

The effects of controlled air flow paths during air sparging on the removal of volatile organic
compounds were examined in this study using a two-dimensional bench-scale physical …

Air sparging was evaluated for remediation of tetrachloroethylene (PCE) present as dense
nonaqueous phase liquid (DNAPL) in aquifers. A two‐dimensional laboratory tank with a …

This study develops methods to estimate the change in soil characteristics and associated
air flow paths in a saturated zone during in situ air sparging. These objectives were …
