Simultaneous dissipation of trichloroethene and arsenic from co-contaminated groundwater by coupling biodechlorination and biodetoxification with assistance of biochar

open access: yesBiochar, 2022
Highlights Biochar enhanced microbes’ metabolic activity by adsorbing TCE and intermediate products allowing them to be degraded on its surface. While biochar itself cannot remove As, it acted as carrier to remove As-laden microorganisms, achieving 70 ...

Integrative Lattice and Surface Engineering of Nanoscale Fe0 for Superior Dechlorination of Trichloroethene in Groundwater: Coordination in Reactivity, Selectivity, and Stability

open access: yesAngewandte Chemie, Volume 137, Issue 27, July 1, 2025.
A lattice and surface engineering strategy was employed to synthesize a novel core‐shell nanomaterial for superior reductive dechlorination of trichloroethene. In this design, FeNi serves as the core and FeS as the shell. Core composition and shell properties interactively determine materials’ performance, and the optimal material exhibited 242.7‐fold ...

Permeable Reactive Barrier Treatment of 1,4‐Dioxane and PFOA Impacted Groundwater Using Powdered Activated Carbon (PAC) Activated Persulfate

open access: yesRemediation Journal, Volume 35, Issue 4, Autumn 2025.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS) and 1,4‐dioxane are emerging groundwater contaminants that persist in the environment, are challenging for in‐situ treatment methods, and have been detected in drinking water systems throughout the United States.

State of the Practice Worldwide: Interaction of Perched and Regional Aquifers at the Site Impacted by Volatile Organic Compounds

open access: yesGroundwater Monitoring &Remediation, Volume 45, Issue 3, Page 58-68, Summer 2025.
Abstract A series of field measurements were used to evaluate the mutual interaction between the perched water zone and the regional aquifer under the specific site conditions of the contaminated site. The perched water zone apparently developed after the demolition of a building used for chemicals by leaving low permeability relics of the building ...

Volatile Short-chain Chlorinated Hydrocarbons in the Groundwater of the City of Zagreb [PDF]

open access: yesKemija u Industriji, 2008
The aim of the study was to assess the quality of the groundwater sampled from private wells and the public water-supply system in terms of estimating the contamination caused by short-chain chlorinated hydrocarbons, as well as to estimate the exposure ...
