Dual Pump Recovery (DPR) System to Extract Freshwater in Coastal Aquifers

Abstract

The paper describes the hydraulic theory of recovering a dense plume using a newly devised dual pump recover system (DPR) and its feasibility to half the remediation time of a contaminated unconfined aquifer in a coastal urban environment. Although the DPR system was successfully applied to clean up the polluted aquifer, the hydraulic principles and techniques are also applicable to extract fresh groundwater from coastal aquifers without the risk of saltwater incursion.
