A New Approach to Transforming Airborne Electromagnetic Data into Models of Sediment Type

open access: yesGroundwater, EarlyView.
A new methodology provides the relationship needed to transform electrical resistivity measurements from airborne electromagnetic surveys to sediment type. By accounting for the physics of the measurement and the quality of the driller's logs used in developing the transform, the method improves the accuracy of derived sediment type models.

Evaluating Suitability for Surface Managed Aquifer Recharge to Enhance Dry‐Season Stream Flows

open access: yesGroundwater, EarlyView.
Identifying suitable sites for surface MAR projects to enhance dry‐season stream flow requires evaluating the geology of the aquifer, depth to groundwater, soil permeability, topographic slope, the distance between the infiltration basin and receiving surface water, and other factors.

Temporal Evolution of Contaminant Mass Discharge: Effect of Source Remediation at Contaminated Sites

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract Contaminant mass discharge (CMD) is a key metric for evaluating remediation performance at contaminated sites posing a risk to groundwater. This study assesses temporal CMD trends and associated uncertainties using a geostatistical approach at a chlorinated solvent contaminated site following source zone remediation, supported by two decades ...

Aquifer Security and the Place of the Aquifer in International Conflicts

open access: yesAvrasya İncelemeleri Dergisi
It is a well-established fact that water is an essential resource for human survival. Consequently, addressing issues related to water resource security and ensuring access to clean water is a top priority for both domestic and foreign policies of nations.

Using the Transition Assessment Teaching Assistant to Evaluate a Transition from Pump and Treat to MNA

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract At many sites, chlorinated ethenes in some of the monitoring wells remain above cleanup goals, even though the water produced by the pumped wells of the pump‐and‐treat system meets the goals. Regulators and site risk managers need tools to determine whether it is appropriate to shut‐down the pump‐and‐treat system and transition to monitored ...

Anaerobic Attenuation of Diisopropyl Ether (DIPE) in Groundwater: Kinetics and Implications for Monitored Natural Attenuation

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract Diisopropyl ether (DIPE) is a branched ether used as a solvent, extractant, and gasoline additive. While aerobic biodegradation of DIPE has been documented, attenuation under anaerobic conditions (typical of groundwater impacted by petroleum hydrocarbons and fuel oxygenates) remains poorly constrained.
