Designing a permeable reactive barrier to treat TCE contaminated groundwater: Numerical modelling / Diseño de una barrera permeable reactiva para el tratamiento de aguas subterráneas contaminadas con tricloroetileno: modelo numérico

Tecnología y ciencias del agua, 2020
A 3-D groundwater numerical model was developed with the software Visual MODFLOW, to design a PRB with brown coal and compost as reactive materials to treat contaminated groundwater with trichloroethene (TCE) in the vicinity of Nowa Dęba waterworks ...

In Situ Colloidal Activated Carbon for PFAS Remediation in Groundwater: Principles, Performance Expectations, and Lessons from the First Decade

Groundwater Monitoring &Remediation, EarlyView.
Abstract Injectable colloidal activated carbon (CAC) has been commercially used to remediate per and polyfluoroalkyl substances (PFAS) in groundwater since 2016. The basis of the technology is enhanced PFAS retention within the aquifer from engineered increases in aquifer‐matrix sorptivity (“PFAS enhanced retention”), with re‐equilibration from the ...

From Energy Deprivation Stress to Catalytic Adaptation of Reductive Dehalogenase TmrA for 1,1‐DCA Dechlorination: An Experimental and in Silico Study

Microbial Biotechnology, Volume 19, Issue 4, April 2026.
Adaptive evolution of Dehalobacter restrictus strain UNSWDHB under a ratio of 1:9 chloroform:1,1‐DCA regime increased 1,1‐DCA dechlorination. Sequencing and molecular dynamics simulation reveal high‐entropy tmrA mutations that improved 1,1‐DCA binding energy and stabilize the catalytic pocket, outlining a route to tune reductive dehalogenases for ...

Environmental Exposures and Autoimmune Diseases: Contribution of Gut Microbiome

Frontiers in Immunology, 2020
Environmental agents have been gaining more attention in recent years for their role in the pathogenesis of autoimmune diseases (ADs). Increasing evidence has linked environmental exposures, including trichloroethene (TCE), silica, mercury, pristane ...

Effect of Moderate Heat on TCE Reductive Dechlorination Rates in Groundwater

Groundwater Monitoring &Remediation, Volume 46, Issue 2, Page 44-54, Spring 2026.
Abstract Low‐temperature heating (in the mesophilic range of ~15 to 40 °C) of contaminated aquifers offers the prospect of increasing the rates for biotic and abiotic treatment of volatile organic compounds. Thermal In Situ Sustainable Remediation (TISR®) is one of the approaches available to implement low temperature heating.

Carbonylative Suzuki–Miyaura Coupling of 1‐Iodoglycals Mediated by the N‐Heterocyclic Carbene Catalyst PEPPSI: Preparation of C‐Acyl Glycosides

European Journal of Organic Chemistry, Volume 29, Issue 7, 23 February 2026.
A multicomponent carbonylative Suzuki–Miyaura reaction was developed for the synthesis of C‐acyl glycosides. Using Pyridine‐Enhanced Precatalyst Preparation, Stabilization, and Initiation (PEPPSI‐IPr) catalysis and Mo(CO)6 as a solid CO source, the reaction enables selective carbonylation of three components in synthetically useful yields, providing a ...

Facilitated Transport of Organic Contaminants in a High Concentration, Multicomponent Plume

Groundwater Monitoring &Remediation, Volume 46, Issue 1, Page 62-83, Winter 2026.
Abstract A field experiment evaluated the transport of organic contaminants in a plume from hazardous waste disposal areas at the Rocky Mountain Arsenal. The plume contained many xenobiotic contaminants, with widely varying expected mobilities.

Intercalation of trichloroethene by sediment-associated clay minerals [PDF]

Chemosphere, 2013
The objective of this research was to examine the potential for intercalation of trichloroethene (TCE) by clay minerals associated with aquifer sediments. Sediment samples were collected from a field site in Tucson, AZ. Two widely used Montmorillonite specimen clays were employed as controls.
