(2024-03)
Article
Open AccessThe fate of selected UV filters (UVFs) was investigated in two soil aquifer treatment (SAT) systems, one supplemented with a reactive barrier containing clay and vegetable compost and the other as a traditional SAT reference ... -
Coupling flow, heat, and reactive transport modeling to reproduce in situ redox potential evolution: application to an infiltration pond
(2020-10)
Article
Open AccessRedox potential (Eh) measurements are widely used as indicators of the dominant reduction–oxidation reactions occurring underground. Yet, Eh data are mostly used in qualitative terms, as actual values cannot be used to ... -
Enhanced NAPL removal and mixing with engineered injection and extraction
(2022-04)
Article
Open AccessAquifer remediation with in-situ soil washing techniques and enhanced oil removal typically involves the injection of liquid solutions into the geological formation to displace and mobilize non-aqueous phase liquids (NAPLs). ... -
Enhancing mixing during groundwater remediation via engineered injection-extraction: the issue of connectivity
(John Wiley & sons, 2023-07)
Article
Open AccessIn the context of in situ groundwater remediation, mixing is vital for a successful outcome. A slow mixing rate between the contaminated groundwater and the injected treatment solution can severely weaken the effective ... -
Fate of sulfamethoxazole in groundwater: Conceptualizing and modeling metabolite formation under different redox conditions
(2016-11-15)
Article
Open AccessDegradation of emerging organic compounds in saturated porous media is usually postulated as following simple low-order models. This is a strongly oversimplified, and in some cases plainly incorrect model, that does not ... -
Feasibility of two low-cost organic substrates for inducing denitrification in artificial recharge ponds: batch and flow-through experiments
(2017-03)
Article
Open AccessAnaerobic batch and flow-through experiments were performed to assess the capacity of two organic substrates to promote denitrification of nitrate-contaminated groundwater within managed artificial recharge systems (MAR) ... -
Granulometry and surfactants, key factors in desorption and biodegradation (T. versicolor) of PAHs in soil and groundwater
(2013-01-10)
Article
Restricted access - publisher's policyHigh hydrophobicity of polycyclic aromatic hydrocarbons (PAHs) is the most limiting factor for the remediation of polluted soils and aquifers. The present study analyzes the effect of three nonionic surfactants (Tween 80, ... -
