Groundwater Modeling and Hydrogeological Parameter Estimation: Potomac Aquifer System, SWIFT Research Center
… (SWIFT) project in eastern Virginia is a Managed Aquifer Recharge project designed to alleviate the depletion of the Potomac Aquifer System due to unsustainable groundwater withdrawals. At the SWIFT Research Center (SWIFTRC) in Nansemond, VA, a pilot testing well (TW-1) has been implemented to …

Investigating the Impact of Aquifer Long Term Replenishment on the Potomac Aquifer System in Virginia
… declines in the potentiometric surface in the Potomac Aquifer System (PAS). With water levels falling, communities are at risk of wells running dry, saltwater intrusion, and land subsidence. The Sustainable Water Initiative for Tomorrow (SWIFT) project is an aquifer long-term replenishment …

Groundwater Modeling of Managed Aquifer Recharge at the Regional and Local Scale
… Roads Sanitation District is heading a Managed Aquifer Recharge project designed to build water resiliency for the district as well as meet recent regulations concerning effluent released into the Chesapeake Bay. The Sustainable Water Initiative for Tomorrow (SWIFT) project will include five …

Groundwater Pumping Decisions and Land Subsidence in the Southern Chesapeake Bay Region of Virginia
… to the hydrologic structure and reliance on the Potomac Aquifer, the Southern Chesapeake Bay region of Virginia has suffered from land subsidence since the 1940s. In coastal regions, land subsidence can increase the risk of flooding. This paper presents a mathematical simulation that predicts …

Addressing climate-driven challenges in groundwater management and coastal hydrogeology through numerical modeling
… chapters examine the SWIFT Project, a managed aquifer recharge initiative for the Potomac Aquifer in coastal Virginia. Numerical models show that injections can induce pressure transients in basement rock, potentially triggering seismicity, but gradual injection increases help mitigate this …

Fluid and Pressure Dynamics in Natural and Engineered Coastal Aquifer Systems
Coastal aquifers are increasingly impacted by groundwater depletion, seawater intrusion, and land subsidence driven by long-term pumping. This dissertation uses 3D numerical modeling to evaluate how variable-density flow and geological heterogeneity influence pressure response, intrusion geometry, …

Evaluation of Soil Aquifer Treatment in a Lab Scale Soil Column Experiment
Soil aquifer treatment (SAT) during managed aquifer recharge has been studied as a method of providing additional environmental barriers to pathogens and contaminants in indirect potable reuse (IPR) applications. A soil column study was conducted by Hampton Roads Sanitation District in order to …

Evaluation of Contaminant Removal Through Soil Aquifer Treatment by a Lab Scale Soil Column Experiment Including a Trace Contaminant Spike Test
Soil aquifer treatment (SAT), the removal of contaminants during percolation through soil, is a strategy employed in managed aquifer recharge (MAR), one method of indirect potable water reuse. As part of Hampton Roads Sanitation District's (HRSD) MAR project, The Sustainable Water Initiative for …

Transport of Per- and Polyfluoroalkyl Substances (PFAS) at a Managed Aquifer Recharge Site
In response to aquifer overuse and its related issues in eastern Virginia, the Hampton Roads Sanitation District (HRSD) is conducting a managed aquifer recharge (MAR) project called the Sustainable Water Initiative For Tomorrow (SWIFT). The objective of the SWIFT program is to treat wastewater to …
