New Documents
In Search of Representativeness: Evolving the Environmental
Data Quality Model. This reprint, entitled "In Search of
Representativeness: Evolving the Environmental Data Quality
Model" was published in the November/December 2002 issue of the
journal Quality Assurance: Good Practice, Regulation, and Law. This
article asserts that data representativeness is fundamental to data

quality, yet the data quality model for contaminant data remains
focused on analytical methods to the neglect of strategies to
accommodate environmental heterogeneity. Advancing technology
enables the cost-effective, high density, adaptive sampling needed
to assure data representativeness, supporting a next generation data
quality model that explicitly manages sampling uncertainties

Guidance on the Use of Passive Diffusion Samplers to Detect
Volatile Organic Compounds in Ground Water Discharge Areas,
and Example Applications in New England (Water-Resources
Investigations Report 02-4186). This document was published by
the USGS, DOI, and EPA. It was prepared under the auspices of the
EPA, Office of Solid Waste and Emergency Response Monitoring
and Measurement for the 21st Century Initiative. The document
provides guidance on passive vapor diffusion (PVD) sampler
assembly, deployment, and recovery to detect volatile organic
compounds in ground-water discharge areas. The report also
discusses the use of PVD samplers at nine Superfund sites in New
England to identify likely discharge areas for VOCs in ground water
(December 2002, 80 pages). View or download at

Study of Five Discrete Interval-Type Groundwater Sampling
Devices (TR-02-12). This report was published by the U.S. Army
Corps of Engineers Cold Regions Research and Engineering
Laboratory. Five relatively newly developed groundwater-sampling
devices (the Kabis, HydraSleeve, Discrete Interval, Pneumo-Bailer,
and USGS Passive Diffusion Bag [PDB] samplers) were tested to
determine their ability to recover representative concentrations of a
variety of analytes, including volatile organics, explosives, pesticides,
and metals (August 2002, 57 pages). View or download at

Calculation and Use of First-Order Rate Constants for
Monitored Natural Attenuation Studies (EPA 600-S-02-500). This
paper was published by the U.S. EPA National Risk Management
Research Laboratory. It explains when and how to apply first-order
attenuation rate constant calculations in monitored natural
attenuation (MNA) studies. First-order attenuation rate constant
calculations can be an important tool for evaluating natural
attenuation processes at ground-water contamination sites. Specific
applications identified in U.S. EPA guidelines (U.S. EPA, 1999)
include use in characterization of plume trends (shrinking,
expanding, or showing relatively little change), as well as estimation
of the time required for achieving remediation goals (November

Risk Management Research Laboratory. It is the first comprehensive
evaluation of the performance of composite and natural bottom
containment liners constructed in accordance with RCRA Subtitle C
(with implications for Subtitle D facilities). The report is a result of
cooperative research between US EPA's ORD, The Geosynthetic
Institute, GeoSyntec Consultants and the University of Illinois. The
document offers detailed study of 187 landfill cells at waste
containment landfill 54 sites. It is arranged in 3 parts: geosynthetic
liner technical issues, soil liner technical issues, field performance
assessments ( December 2002, 1004 pages). View or download by

NATO/CCMS Pilot Study Evaluation of Demonstrated and
Emerging Technologies for the Treatment of Contaminated
Land and Groundwater (Phase III) Reports. The Council of the
North Atlantic Treaty Organization (NATO) established the
Committee on the Challenges of Modern Society (CCMS) develop
programs to share information among countries on environmental
and societal issues that complement other international endeavors
and to provide leadership in solving specific problems of the human
environment. They have produced three new documents, which
