Evaluating the sustainability of monitored natural attenuation in groundwater at chlorinated ethene contaminated sites
Monitored natural attenuation (MNA) has been widely used as a remedial strategy, acknowledged by the EPA as the most appropriate technology for cost effective remediation under certain site conditions. Despite the widespread use of MNA, empirical methods are lacking to evaluate the sustainability …

Sustainability of Reductive Dechlorination at Chlorinated Solvent Contaminated Sites: Metrics for Assessing Potentially Bioavailable Natural Organic Carbon in Aquifer Sediments
… and economical remedial technologies. Monitored natural attenuation (MNA) has become accepted by federal regulatory agencies as a viable remediation strategy for contaminants under site-specific conditions. At chloroethene contaminated sites where MNA is used as a remediation strategy, …

Sequential Electron Acceptor Model of Intrinsic Bioremediation at a BTEX Contaminated LUST Site in Laurel Bay, South Carolina
… aid engineers in evaluating the feasibility of natural attenuation as a remediation alternative in groundwater systems. In this research, a three-dimensional sequential electron acceptor computer model, SEAM3D, developed by Waddill and Widdowson (1997) was used to simulate contaminant transport …

Design Methodology for Permeable Reactive Barriers Combined With Monitored Natural Attenuation
… not properly account for all major physical and attenuation processes driving remediation. This study focused on developing a simple methodology to design PRBs that is easy to implement while improving accuracy and being more conservative than the available design methodologies. An empirical …

Evaluating the Occurrence, Fate and Human Health Risks of Contaminants of Emerging Concern in the Atlantis Managed Aquifer Recharge Scheme
… with exposure to CECs and assesses the aquifer’s natural attenuation capacity, given the absence of advanced treatment either prior to recharge or post abstraction within the current MAR scheme. Samples were collected in 2019, 2021, and 2023 from MAR source water, groundwater, and surface water …
