New Site-Specific Technical Assistance Available. The U.S.

Army Corps of Engineers has a new agreement with EPA to provide
site-specific technical assistance for site managers who would like to
consider using systematic planning, field measurement
technologies/real time data generation, and a dynamic work plan,
which is referred to as the Triad approach. The Corps can provide
experienced technical staff to help determine if there are field
measurement technologies (such as XRF, immunoassay, on site GC
or GC/MS, and direct push sensors) that might optimize data
collection activities. Use of the Triad approach can often result in
significant total cost savings by allowing project managers to reach
site decisions while avoiding numerous planning efforts and field
mobilizations that would otherwise be necessary. In addition, use of
the Triad approach can assist with the management of decision
uncertainty by increasing the sampling density possible for the
money available and/or by designing sample collection to yield the
most valuable information. Because of its flexible approach, the
Triad process is applicable to all data collection activities, including
initial site screening, characterization, remediation, and monitoring.
This technical assistance is available, at no initial cost, to EPA site
managers (and to states through EPA) who are managing
Superfund, RCRA, UST, or Brownfields sites. For more information,
call Kira Lynch at 206-764-6918 or e-mail p.lvnch@usace.armv.mil.

New Documents and CD ROMs

Abstracts of Remediation Case Studies Volume Six (EPA
542-R-02-006) This report was published by the Federal
Remediation Technologies Roundtable. It is a collection of abstracts
summarizing 39 case studies of site remediation applications
prepared primarily by federal agencies. The case studies were
undertaken to document the results and lessons learned from
technology applications. They will help establish benchmark data on
cost and performance which should lead to greater confidence in the
selection and use of cleanup technologies (June 2002, 139 pages).

FRTR Cost and Performance Remediation Case Studies and
Related Information (EPA 542-C-02-004). This CD, produced by
the Federal Remediation Technologies Roundtable, contains 313
cost and performance reports about full-scale remediation projects
and large scale demonstrations. The new additions include case
studies addressing cleanup of contaminated groundwater using in
situ technologies such as bioremediation, surfactant flushing,
chemical oxidation, thermal treatment, permeable reactive barriers,
phytoremediation, air sparging, and in-well air stripping. In addition,
the CD ROM provides 110 case study reports about site
characterization and monitoring technologies, and seven reports

Innovative Remediation Technologies: Field-Scale
Demonstration Project Database and Report. EPA has expanded
and revised the interface of its online, searchable database of
completed and ongoing field-scale demonstrations of innovative
hazardous waste remediation technologies. Through the database,
information on 663 projects can be searched by media, technology
type, contaminant type, and demonstration date to help users find
reference and contact information for projects that match their
cleanup needs. Also, the interface now allows users to submit
information on projects for inclusion in the database (after EPA
review). An electronic version of the Year 2000 Report, containing
information on projects up to June 2000, is available for download.

updated its guidance to reflect the latest evaluation of currently
available data and technologies for VOC sample handling and
preservation procedures for solid samples. The procedures are
designed to minimize VOC losses through the two most common
mechanisms, volatilization and biodegradation. This guidance
appears in SW-846 Method 5035A, which includes a 30-page
appendix of detailed explanatory material (July 2002, 69 pages).

An Assessment of Protocols for Splitting Soil Samples. The

heterogeneous particulate nature of soil samples can cause wide
variability in analytical results if the subsampling and sample splitting
procedures used are not carefully selected and controlled. This
study (published on-line May 14, 2002 through the Journal of
Chemometrics by Gerlach et al.) demonstrates the ability of riffle
splitting to minimize subsampling error. In contrast, grab sampling
(the most common form of subsampling) produced the worst data
quality. Sample mixing prior to grab sampling may not be sufficient
to avoid sampling errors when matrices are composed of
particulates of different sizes and densities, as is typical of
environmental soils. Sampling accuracy was at least 2 orders of
magnitude worse than the analytical method accuracy of this study
(September 2001, 8 pages). View or download athHn-//m.-in nmfenhni,hSMm .

Report of the Nicole Workshop: Cost Effective Site
Characterization Dealing with Uncertainties, Innovation,
Legislation Constraints. This report summarizes the conference
sessions at the April 2002 meeting in Pisa, Italy. The goal of the
workshop was to investigate the optimization of investigation costs
versus more accurate knowledge of pollution at a site (June 2002, 48
pages). View or download at http://www.nicole.ora/ .

Monitoring Well Comparison Study: An Evaluation of
Direct-push Versus Conventional Monitoring Wells. This study
was conducted by BP Amoco in partnership with U.S. EPA Regions
4 and 5. This project was undertaken to determine whether
measurements of groundwater parameters obtained using
direct-push wells are comparable to those obtained from
conventional monitoring wells. Direct-push monitoring wells
contained no filter pack and were pushed into the subsurface;
conventional monitoring wells contained filter packs and were
installed with typical drilling and completion methods. The measured
parameters were groundwater levels, chemical concentrations
(BTEX, MTBE, TSS, and naphthalene), hydraulic conductivity, and
natural attenuation (geochemistry) parameters. The study was
conducted at two sites in Ohio and two sites in Georgia and they

Spill Prevention Control and Countermeasure Rule (40 CFR
112). On July 17th, 2002, EPA issued a final rule amending the Oil
Pollution Prevention regulation promulgated under the authority of
the Federal Water Pollution Control Act (Clean Water Act). This rule
addresses requirements for Spill Prevention Control and
Countermeasure Plans (SPCC Plans) and some provisions may also
affect Facility Response Plans (FRPs). The new SPCC rule
addresses will become effective August 16, 2002 and applies to
owners or operators of facilities that drill, produce, gather, store, use,
process, refine, transfer, distribute, or consume oil and oil products.
