Abstract Remediation of per‐ and polyfluoroalkyl substances (PFAS) in groundwater is particularly challenging because their unique chemical fate transport properties. Many conventional in‐situ remediation technologies, commonly applied to address other contaminants, have proven ineffective for treatment PFAS. Given stability, destruction PFAS has remained elusive as an option. Consequently, new approaches manage plumes are great interest environmental practitioners. We propose that enhancing...
The use of bioaugmented zeolite (bio-zeolite) can be an effective technology for irreversibly removing recalcitrant organic pollutants in aqueous mixtures. Removal 1,4-dioxane by a bio-zeolite (Pseudonocardia dioxanivorans CB1190-bioaugmented ZSM-5) the presence several chlorinated volatile compounds (CVOCs) was superior to removal adsorption using abiotic zeolite. Mixtures containing 1,1-dichloroethene (1,1-DCE) were exception, which completely inhibited system. Specific characteristics...
1,4-Dioxane is one of the most frequently detected organic water contaminants and often co-occurs with chlorinated volatile compounds due to its use as solvent stabilizer. Its recalcitrance challenges natural attenuation processes conventional treatment technologies. Here, we examined bioelectrochemical oxidation 1,4-dioxane using dimensionally stable mesh electrodes in flow-through reactors coupled bioaugmentation by Pseudonocardia dioxanivorans CB1190. influent concentrations were rapidly...
Abstract Current ex situ per‐ and polyfluoroalkyl substances (PFAS) remediation strategies often involve the treatment of large volumes PFAS‐impacted water via separation processes to concentrate PFAS for subsequent or disposal. This study presents a new method concentrating that relies on colloidal gas aphrons (CGAs), unusual microstructures composed water, multilayers surfactants, air, can be used electrostatic hydrophobic sorption. successfully demonstrates efficacy CGAs in removing ionic...
Abstract Accelerating the remediation of contaminants that have diffused into low‐permeability (low‐k) geologic units such as silts and clays is a key need for groundwater industry. Injection‐based remedial technologies are often ineffective because injected amendments more likely to influence transmissive media (sands sandy silts) generally do not penetrate low‐k units. While some emerging now being tested, they expensive or other technical limitations (e.g., installation depth rate...
