Green Remediation: Best Management Practices for Excavation and Surface
Restoration (EPA 542-F-08-012). This quick-reference fact sheet provides examples
of planning and field strategies for increasing sustainability of contaminated soil or
sediment excavation and subsequent land restoration under any regulatory framework.
The document focuses on opportunities to reduce the negative impacts of excavation,
such as high rates of fuel consumption, transport of air-borne contaminants,
uncontrolled stormwater runoff, soil erosion, and ecosystem disturbance. Green
remediation encourages decision-makers to weigh the environmental and economic
tradeoffs of implementing remedies such as excavation and to closely coordinate
remedy implementation with long-term site use (December 2008, 4 pages). View or

Environmental Technology Verification (ETV) Program Materials Management
and Remediation Center. The ETV Program is pleased to announce the addition of
the new Materials Management and Remediation (MMR) Center. Battelle Memorial
Institute has been awarded the cooperative agreement to operate the new MMR
Center. This center will verify materials management technologies, including for
recycling, beneficial use of waste materials, recovery of useful components of waste,
and treatment to minimize disposal requirements (e.g., containment, volume, cost). The
MMR Center will also verify technologies to remediate contaminated land and ground
water, such as is found at Superfund sites and other properties where industrial or
commercial activities have resulted in a legacy of hazardous constituents that limit
future use of the property. For more information, visit

Comparison of Pumped and Diffusion Sampling Methods to Monitor
Concentrations of Perchlorate and Explosive Compounds in Ground Water,

Camp Edwards, Cape Cod, Massachusetts, 2004-05. Laboratory and field tests were
conducted at Camp Edwards on the Massachusetts Military Reservation on Cape Cod
to examine the utility of passive diffusion sampling for long-term monitoring of
concentrations of perchlorate and explosive compounds in ground water. The results of
laboratory tests in which diffusion samplers were submerged in containers filled with
ground water containing perchlorate, RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine), and
HMX (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine) indicate that concentrations
inside the diffusion samplers equilibrated with concentrations in the containers within
the 19-day-long test period. The results of the field tests indicate generally good
agreement between the pumped and diffusion samples for concentrations of

An Overview of Land Use Control Management Systems (ITRC BRNFLD-3). This
document presents an overview of various systems and state programs that track,
monitor, and/or educate people on Land use controls (LUCs). Moreover, it describes
each of these systems and programs and explains what and how information is provided
by each system. Information about the various technologies and their associated costs
for development and implementation is provided, advantages and limitations are
discussed, potential users are identified, contact information for the user is provided,
and case studies offer insight into implementation efforts. It is important to note that,
due to the ongoing and sometimes contentious debate about the .appropriateness, of
LUCs in comparison to permanent, active, or .complete, remedies, this document does
not evaluate the policy issues related to LUCs or their role as part of an appropriate
solution to any specific environmental condition (December 2008, 134 pages). View or

Quality Considerations for Munitions Response Projects (ITRC UXO-5). In this
document the ITRC Unexploded Ordnance (UXO) Team provides guidance to
environmental regulators on how to define quality, how to systematically plan for and
achieve quality results, and how to apply these concepts to processes common to a
munitions response (MR) project. The document also provides real-world examples to
illustrate how the proper or improper application of the quality concepts presented in
this document affect the .quality, of MR projects.In this document, quality is defined as
.conformance to requirements.. To manage quality, the quality requirements of the
project must first be understood. Requirements must be precisely stated and clearly
understood by everyone involved. A plan is then put in place to meet those
requirements. The UXO Team emphasizes taking a whole-system approach to
designing and managing an MR project to optimize quality (October 2008, 83 pages).

In-Situ Chemical Oxidation: A Study of the Current State of the Technology. This
document was prepared by Matthew West during an internship with the U.S.
Environmental Protection Agency, sponsored by a Cooperative Agreement with the
University of Arizona. Chemical oxidation is one of the many different methods of site
remediation that has emerged lately as an alternative method to traditional techniques.

-------
Chemical oxidation is based upon the theory that by introducing certain reactive
chemicals into the contaminated aquifer, the contaminant in question can be converted
into less harmful compounds in a relatively automated process. After the reactive
chemicals (reagents) are introduced into the aquifer, they work by themselves and are
driven by the internal chemical energy. Furthermore, chemical oxidation has been
shown to be effective at the destruction of the dissolved phase of non-aqueous phase
liquids (NAPL), which are known to be difficult to remediate through other tactics.
Therefore, if administered correctly, in-situ chemical oxidation (ISCO) has the potential
to be a low-cost, fast, effective, and relatively low maintenance remediation technology
(August 2008, 9 pages). View or download at http://www.ciu-in.ora/techpubs.htm .

Report of the NICOLE Workshop: Environmental Decision Support Systems 9-10
October 2008 Madrid, Spain. (2008). Decision support tools (DSTs) integrate
environmental data and simulation or conceptual models into a framework for
supporting decision-making for site characterisation, monitoring, or remediation. DSTs
are tools that facilitate the use of data, derivations and models and/or structure the
processes in decision making. This workshop presented a range of decision support
tool/system functions with some examples and case studies. Its discussion related to
the capabilities and limitations of such tools and systems and their degree of
acceptance in daily decision making processes. View or download at

RTD RESULTS: USE, EXPLOITATION AND COMMUNICATION

EXPERIENCES ECODIS project. ECODIS is an FP6 specific target research project

on dynamic sensing of chemical pollution disasters and predictive modelling of their

spread and ecological impact. The project is close to completion and the final

integrating activities have included an international conference on

'Chemodynamics of Ecosystems' at the Centra Stefano Franscini, Monte

Verita, Switzerland (abstracts are available at www.eawaa.ch/chemdvn').

The outcomes of ECODIS were disseminated to potential end users at a

workshop on 28 November at the JRC-IHCP in Ispra, IT. The dynamic

approach to risk assessment developed by the project involves

measurement and modelling of spatial and temporal distributions of

pollutants and their biological impacts, coupled with macro-scale flows in

a water body. A technical guidance document on pollution disaster

monitoring and ecological impact prediction will be available in early 2009.
