RODs selecting pump and treat have decreased from
near 90% in the early 1990s to about 40% in FY 2002,
while RODs selecting in situ groundwater treatment
have been generally increasing to 24% in FY 2002,

Treatment Technologies for Site Cleanup:
Annual Status Report (Eleventh Edition)
Fact Sheet
The U.S. Environmental Protection Agency's (EPA) Office
of Superfund Remediation and Technology Innovation
(OSRTI) encourages the use of innovative, cost-effective
technologies for the characteri2ation and treatment of
contaminated waste sites, soils, and groundwater. To
achieve that goal, OSRTI works with many partners inside
EPA, in other federal agencies, and in the private sector
to identify better, raster, and cheaper options for cleanup.
OSRTI is pleased to announce the availability of the
eleventh edition of the Treatment Technologies for Site
Cleanup: Annual Status Report (ASR), EPA 542-R-03-009,
which documents the use of treatment technologies at
hazardous waste sites. The report presents a list and
analysis of remedial actions at Superfund sites where
treatment technologies are being used. Site managers can
use this report to evaluate cleanup alternatives for similar
sites, while technology vendors can use it to identify
potential markets for their products. EPA also uses the
information to track progress in the application of
established and innovative treatment technologies.
Treatment Technologies for Site Cleanup:
Annual Status Report (Eleventh Edition)
The Eleventh Edition documents,
as of March 2003, the status of
technology applications at more
than 1,800 soil and
groundwater projects in the
Superfund program. The
report examines both in situ
and ex situ source control
technologies (addressing
soil, sludge, sediment,
other solid-matrix
wastes, and non-aqueous phase
liquids [NAPL]), as well as in situ groundwater
treatment technologies and pump and treat (P&T) for
groundwater. The principal technologies for the treatment of
soil and other solid wastes that are discussed in the reporr are
soil vapor extraction (SVE), solidification/stabilization, on-
and off-site incineration, bioremediation, and thermal
desorption. The in situ groundwater treatment technologies
included in this report are air sparging, bioremediation,
chemical treatment, permeable reactive barriers, multi-phase
extraction, phytoremediation, in-well air stripping, in situ
thermal treatment, and flushing. Groundwater containment
using vertical engineered barriers is also included in this report.
Some findings of this report include:
• At almost two-thirds (62%) of Superfund sites, source
control or groundwater treatment has been
implemented or is currently planned.
• The complexity of RODs has been increasing. The
proportion of RODs addressing both soil and
groundwater contamination has increased from 20%
in FY 1997 to 56% in FY 2002.
* Of the 2,610 RODs and ROD amendments signed,
some 1,505 (58%) included treatment remedies.
• In situ technologies make up 42% of all source control
treatments.
* Groundwater treatment was selected at 71% of
Superfund sites that selected a groundwater remedy.
• 31% of source control and groundwater treatment
projects have been completed, and an additional 39%
are operational.
