Biodegradation and biotransformation of contaminants in groundwater commonly occurs
naturally. However, natural biodegradation rates can be slow leading to elongated …

Polymer solutions aid DNAPL (Dense Non Aqueous Phase Liquid)-contaminated soil
remediation but are impacted by gravity and viscous forces. This study assesses the …

The ability to reliably deliver and widely distribute remedial amendments through the
subsurface environment is of paramount importance to achieve cleanup objectives for …

Foam in porous media has been studied as a tool for various applications. Recently, the
technology has become relevant for contaminated-aquifer remediation, where porous media …

Foam propagation and stability in highly permeable porous media, encountered in soil
pollution applications, are still challenging. Here, we investigated the application of foam for …

The removal of chlorinated organic hydrocarbons (COHs)-DNAPLs was studied in
permeability-contrasted sandboxes with an egg-box shaped substratum. Aqueous solutions …

Foam has shown promising characteristics for soil remediation, especially as a blocking
agent. In very permeable porous media, high groundwater velocity reduces the efficiency of …

Agrochemicals and fertilizers are central to modern agriculture and are credited with the
large increase of crop yield as a part of the Green Revolution of the 1960's. Timely and …

Foam injection is a promising option for soil remediation applications. However, predicting
how it will propagate in highly permeable aquifers under groundwater flow is challenging …

Studies of foam flow in highly permeable porous media are still limited due to foam's
complex behavior and discrepancies in foam research. Specifically, it is still unclear how …
