Improving Effectiveness of Bioremediation at DNAPL Source Zone Sites by Applying Partitioning Electron Donors (PEDs)

Abstract

Partitioning electron donors (PED) are electron donors that partition directly into a target dense non aqueous phase liquid (DNAPL). PEDs are water soluble, hence are easily transported to a DNAPL source zone. This property aids in their mixing throughout the source zone and maximizes contact with the DNAPL. Even at high dose rates, PEDs are slowly metabolized, which facilitates delivery without significant loss and allows efficient distribution throughout the source zone. The objectives of the field demonstration/validation (DEM/VAL) included: (1) Demonstrate application of the PED technology at field scale, assess the ability to distribute PED within the source area and enhance biodegradation; (2) Validate the enhanced performance and efficiency of DNAPL dissolution and dechlorination following the injection of a PED; and (3) Collect cost and performance data for the application of PEDs for source zone bioremediation.
