Executive Summary of Demonstration of Surfactant-Enhanced Aquifer Remediation of Chlorinated
Solvent DNAPL at Operable Unit 2, Hill AFB, UT, INTERA (a Duke Engineering & Services
Company). Direct quotes are from Rice University, 1997:
During the summer of 1996, INTERA conducted a successful demonstration of surfactantenhanced
aquifer remediation (SEAR) in collaboration with the Center for Petroleum and
Geosystems Engineering at the University of Texas at Austin (UT) and with Radian International.
The US Air Force Center for Environmental Excellence (AFCEE) funded the necessary DNAPLzone
characterization and surfactant-flood demonstration. The Center for Petroleum and
Geosystems Engineering at UT funded the design of the surfactant floods, and Hill AFB near
Ogden, Utah provided extensive logistical support. The University of Texas performed the design
of the surfactant flood and a partitioning tracer test, and RADIAN International performed the
treatment engineering. INTERA, Inc. was the principle contractor and performed all field injectionextraction
operations and applied for all permits. As is documented in this report, SEAR meets the
requirements set down by the Defense Department's DNAPL Integrated Product Team (IPT) for
cost-effective detection and remediation of chlorinated-solvent DNAPL zones.
The demonstration was conducted at Operable Unit 2 (OU2) at Hill AFB, which had received large
volumes of chlorinated solvents from degreasing operations conducted at the base. OU2 is a
closed chemical disposal area underlain by an alluvial sand aquifer confined on its sides and below
