Groundwater, EarlyView.Abstract We propose that a new term, aquitardifer, be added to the hydrogeologic nomenclature. Aquitardifer, a blend of the terms aquitard and aquifer, accounts for geologic materials that have properties of both as traditionally defined. Several examples of aquitardifers are provided, as is justification for and applicability of the term.

Groundwater, EarlyView.Abstract Solute transport simulators aiming to accurately describe the transport of charged chemical species in porous media need to account for electrostatic coupling effects. Each ion in pore water possesses a specific electric charge and molecular diffusion coefficient, properties that determine their mobility and the overall charge balance of ...

Mapping High‐TDS Groundwater Near Impoundments Using Ground and Waterborne Towed Electromagnetics
Groundwater, EarlyView.Abstract Long‐term monitoring at landfills and impoundments containing coal combustion products (CCPs) or other industrial wastes is essential for detecting possible leachate releases to groundwater and mapping contamination plumes. This study evaluates a novel, non‐invasive geophysical approach—towed time‐domain electromagnetic (TEM) surveys—for non ...

Teaching Aquitard Concepts With Field‐Based High‐Resolution Head Profile Learning Activities
Groundwater, EarlyView.Abstract Aquitards play critical roles in a variety of hydrogeologic processes. Despite their importance, coverage of aquitards in introductory hydrogeology textbooks is generally limited. This paper provides examples of classroom and field activities designed with an aquitard focus for instructors wishing to supplement textbook content.

Groundwater Transport in a Glaciomarine Aquitard: Paleosalinity and Landslide Implications
Groundwater, EarlyView.Transient 1D modeling of both [Cl] and δ18O demonstrates that advection and diffusion contribute to solute transport in porewater of glaciomarine Champlain Sea muds. Samples with the highest sensitivity (>30) for landslide hazard occur in the current leached zone.
