Abstract

This modeling study evaluated the capability of low-capacity wells injecting clean water and nonpumped wells equipped with filter media for containing and removing a contaminant plume in groundwater. Outcomes were compared for configurations of: (1) nonpumped wells, (2) nonpumped wells and injection wells (injecting less than 1 m3/d), and (3) no wells (baseline scenario). Results suggest that hybrid configurations featuring both types of wells can be an effective, low-cost strategy for containing and remediating contaminated groundwater. Strategically positioned injection wells funnel contaminant plumes toward nonpumped wells, thus requiring fewer nonpumped wells to contain and remove a contaminant plume. © 2013 Wiley Periodicals, Inc.
