done at the Burlington Northern Somers site in Somers, Montana. The ground water
pump and treat system, installed in 1994 to treat ground water contaminated by wood
preservatives used in the treatment of railroad ties, was shut down in 2007 under a
technical impracticability waiver. This report reviews the conceptual model developed
for the site and evaluates the validity of assumptions of the analytical transport model,
its consistency with site conceptual model, and the reasonableness of its conclusions.
The report suggests an approach for evaluating plume stability prior to, and subsequent
to, the shutdown of the pump and treat system and recommends how to evaluate site
data collected during the two-year shutdown. The report also recommends point of
compliance monitoring points for the site and evaluates the adequacy of the spatial
distribution of ground water monitoring locations for monitoring of flow directions and
contaminant transport (April 2009, 30 pages). View or download at

Final Report: Technical Assistance for the Idaho Pole Site, Bozeman, Montana
(EPA 542-R-09-001). This technical assistance report was prepared for EPA Region 8
to help evaluate the existing ground water remedies at the Idaho Pole site-a former
wood treatment site contaminated with creosote and pentachlorophenol-in Bozeman,
Montana. The report evaluates potential in situ treatment options for ground water
"hot-spots" and the potential change from reinjecting treated water to discharging it to
surface water. It also evaluates potential alternatives for the collection and in situ
treatment of oil found beneath an interstate highway near the site. The report suggests
a potential framework for discontinuing the existing pump and treat system and
qualitatively reviews the ground water monitoring network to identify deficiencies and
redundancies. The report also assesses whether adequate data exist to perform a
capture zone analysis and outlines the steps involved in conducting the capture zone
analysis. Finally, the report estimates the amount of water that might be produced from
dewatering during installation of utilities along the interstate highway (April 2009, 34
pages). View or download at http://clu-in.ora/techpubs.htm .

Reported Leaks, Spills and Discharges at Florida Drycleaning Sites. This paper
presents data collected by the Florida Drycleaning Solvent Cleanup Program on
reported spills, leaks and discharges of drycleaning solvent and solvent-contaminated
wastes at 334 drycleaning facilities and 14 drycleaning wholesale supply facilities
located in Florida. This information will be useful to those conducting contamination
assessments and soil and groundwater remediation at contaminated drycleaning sites
by helping to identify contaminant source areas. Since the bulk of the contaminant
mass is generally located in close proximity to the discharge point, a better
understanding of drycleaning equipment, operations and waste management practices,
particularly former industry practices, will facilitate identification of contaminant source
areas. This will enable investigators to focus sampling during site assessment activities
to provide a more accurate picture of contaminant mass distribution in contaminant
source areas that is necessary for successful site remediation. Information contained in
this paper may also be useful to regulatory personnel conducting compliance
inspections at drycleaning operations (April 2009, 14 pages). View or download at

Evaluating Natural Source Zone Depletion at Sites with LNAPL. Light,
nonaqueous-phase liquid (LNAPL) refers to an organic compound that is immiscible
with, and lighter than, water (e.g., crude oil, gasoline, diesel fuel, heating oil). When an
LNAPL is released to the subsurface, it can migrate downward under the force of
gravity and laterally at the water table. Larger LNAPL releases may migrate to the
water table while leaving residual, immobile LNAPL along the migration path. The
constituents, or chemicals, that compose the LNAPL may be removed overtime by
various mechanisms, such as sorption, volatilization, and dissolution. If not removed,
the LNAPL "body" can function as a potentially long-lived source zone for secondary
impacts to adjacent soil, soil gas, and groundwater. A simple, quantitative mass

balance assessment of source zones could conclude that, if some quantities of
constituents are naturally being lost from the source zone at some rate due to natural
processes, then the source zone itself must be depleting to some degree. The key
question then becomes, at what rate is this natural source zone depletion (NSZD)
occurring? This document addresses this and other questions associated with NSZD
(April 2009, 76 pages). View or download at http://www.itrcweb.ora/Documents/LNAPL-1 .pdf .

Vapor Intrusion Mitigation Advisory. Designed to be used when the risk accorded to
vapor intrusion has been estimated and measures are proposed to address the vapor
intrusion pathway. Provides a framework that guides the reader through the decision
process for 1) determining if mitigation is appropriate for the project site, 2) selecting a
mitigation system that is protective of human health, and 3) ensuring that
implementation is sustainable for the duration of mitigation. Emphasizes public
participation and implementation considerations (e.g., operation and maintenance,
monitoring) (April 2009, 77 pages). View or download at

Triad Issue Paper: Using Geophysical Tools to Develop the Conceptual Site
Model (EPA 542-F-08-007). This technology bulletin explains how
hazardous-waste site professionals can use geophysical tools to provide
information about subsurface conditions to create a more representative
conceptual site model (CSM). The CSM is a tool for gaining a synergistic
understanding of the site, improve cost effectiveness, and improve decision-making
within the Triad approach. Geophysical tools can be applied to create more robust
CSMs with more complete data sets that result in a more representative and accurate
depiction of the site characteristics at Brownfields and other hazardous waste sites

Remediating and Monitoring White Phosphorus Contamination at Eagle River
Flats (Operable Unit C), Fort Richardson, Alaska (ERDC/CRREL LR-08-04). This is
the eighteenth annual contract report prepared by researchers from CRREL and other
Federal agencies for the U.S. Army Garrison Alaska, Public Works, describing results of
research, remediation, and monitoring efforts addressing white phosphorus (WP)
contamination in Eagle River Flats, an 865-ha estuarine salt marsh on Fort Richardson,
Alaska. Over the five-year period from 1999-2003, full-scale remediation was
performed at Eagle River Flats using six remote-controlled pumps to temporarily drain
contaminated ponds, allowing the sediments to dry and the WP to oxidize. This effort
successfully remediated about 90% of the ponds. More recently, limited remediation
using one or two pumps has been conducted to address the remaining few
white-phosphorus-contaminated areas (May 2008, 136 pages). View or download at
