Since July 1, TechDirect gained 257 new subscribers for a total of
6880. Welcome to all the new subscribers! We hope this service
continues to meet your needs.
Need to change your TechDirect subscription address? Remember,
you can change your subscription address any time at http://clu-in.org/techdrct
. Also, I have heard from a few long time subscribers that
mysteriously they no longer receive the monthly updates. The EPA
mail server in North Carolina has an automatic delete function that
removes addresses that it thinks are no longer valid from listservers.
It is supposed to delete addresses that come up as undeliverable
four consecutive deliveries. I am investigating how it works exactly
and whether or not that function can be modified. If, in the future you
realize that you are no longer receiving TechDirect and still want to,
you will need to resubscribe. I apologize for this inconvenience.
Remediation Documents
Envirometal Technologies, Inc. Metal Enhanced Dechlorination
of Volatile Organic Compounds Using an In Situ Reactive Iron
Wall (EPA 540-R-98 501). This report was published by EPA under
its Superfund Innovative Technology Evaluation (SITE) program. It
documents the results of a demonstration at an undisclosed site in
central New York. The results of the sample analyses indicated that
the technology significantly reduced concentrations of contaminants
passing through the wall (September 1998, 104 pages). View or
download at, http://www.epa.aov/QRD/SITE/reports/540r98501 .pdf .
Regulatory Guidance for Reactive Permeable Barriers Designed
to Remediate Metals and Radionuclides in Groundwater
(PBW-3). This document was published by the Interstate
Technology and Regulatory Cooperation (ITRC) Work Group. It was
developed to try to address the regulatory requirement of Permeable
Reactive Barriers (PRBs) and try to achieve state consensus on the
requirements. It is divided into sections dealing with site
characterization, modeling, permitting, construction, monitoring,
waste management, closure, health and safety and stakeholders
concerns [December 1998, 67 pages]. View or download at

Software.

This report was sponsored by the U.S. Department of Energy. It
evaluates nineteen Decision Support Software (DSS) codes on a
screening level in order to provide information to decision-makers on
the utility of a particular code to a site specific application. The
software packages analyzed addressed some or all of the following
decision categories: remedy selection, remedial design optimization,
cost benefit analysis, site characterization, plume characterization,
and/or risk assessment issues [June 1997, 45 pages]. View or

Using Simulation-Optimization Techniques to Improve
Multiphase Aquifer Remediation. This report was published by the
Lawrence Berkeley National Laboratory. The T2V0C computer
model for simulating the transport of organic chemical contaminants
in non-isothermal multiphase systems has been coupled to the
iT0UGH2 code which solves parameter optimization problems. This
allows one to use linear programming and simulated annealing
techniques to solve groundwater management problems, i.e. the
optimization of operations for multiphase aquifer remediation. A cost
function has to be defined, containing the actual and hypothetical
expenses of a cleanup operation which depend - directly or indirectly
- on the state variables calculated by T2V0C. Subsequently, the
code iteratively determines a remediation strategy (e.g. pumping
schedule) which minimizes, for instance, pumping and energy costs,
the time for cleanup, and residual contamination. An illustrative
sample problem is outlined to discuss potential applications of the
code. See http://ccs.lbl.aov/ITOUGH2/Biblioaraphv/Abstract/CON SimQpt.html.
Natural Attenuation of Chlorinated Solvents in Ground Water:
Principles and Practices This document was published by the
Industrial members of the Remediation Technologies Development
Forum (RTDF) and the Interstate Technology and Regulatory
Cooperation (ITRC) Work Group. This document is not a how-to
document, rather its purpose is to provide a framework to evaluate
natural attenuation of chlorinated volatile organic compounds [May
1999, 123 pages]. View or download at http://clu-in.org/conf/itrc/natatt/p&p.pdf .
Ground Water Currents (EPA 542-N-99-004). Ground water
Currents is a quarterly update that provides descriptions and
performance data for developments in innovative ground water
treatment. This issue features new techniques for ground water
monitoring and active remedies for ground water contaminated with
organics [July 1999, 4 pages]. View or download at http://clu-in.ora/techpubs.htm

Technology Highlight - Composting
Analysis of Compost as an Environmental Remediation
Technology (EPA 530-R-98-008). This report was published by the
EPA Office of Solid Waste. It summarizes the available information
on the use of compost for managing hazardous waste streams (as
well as other applications) and indicates possible areas for future
investigations [April 1998, 115 pages]. View or download this
document at http://www.epa.aov/compost [Note: the document consists of four
PDF files]. For hard copies contact (800) 490-9198 or (513)
489-8190 or fax your request to (513) 891-6685.
Compost - New Applications for an Age-Old Technology (EPA
530-F-97-047). This is a collection of fact sheets developed by
EPA's Office of Solid Waste that address many innovative and
cost-effective uses of compost to remediate or prevent pollution. The
fact sheets discuss how compost can be used to remediate
contaminated soils; remove oil, grease, and heavy metals from
storm water runoff; destroy VOC's; facilitate reforestation, wetlands
restoration, and revitalize wildlife habitats. The individual fact sheets
from this collection are listed below and may be downloaded at
http://www.epa.aov/compost [All are between 4-8 pages]. For hard copies
contact (800) 490-9198 or (513) 489-8190 or fax your request to

Fractured Rock Site Profiles. The U.S. Environmental Protection
Agency's Technology Innovation Office (TIO), in cooperation with
the Interstate Technology Regulatory Cooperation (ITRC)
workgroup, is assembling information on efforts to identify and
remediate contaminated fractured rock sites. Our goal is to establish
a series of 1 to 2 page site profiles that will identify the nature and
extent of the contamination problems at such sites, geology affecting
site assessment and remediation efforts, characterization and
