Correct Implementation of the Argonne Expedited Site Characterization (ESC) Process for Preremedial Site Investigations

Jacqueline C. Burton, John L. Walker, Robert Sedivy, and Stephen Cook, Argonne National Laboratory, Environmental Research Division (INDOOR)

The purpose of this workshop is to introduce participants to the ESC process and provide guidelines for conducting a successful ESC field program for a variety of site types, sizes, and regulatory settings. The Argonne ESC Progress is an effective, cost- and time-saving approach for technically suffessful remedial site investigations. It is presently being used by many federal agencies as the correct approach to CERCLA RI/FS and RCRA TFI/CMS investigations. Fundamental to the ESC process is an understanding of geologic and hydrogeologic controls at a site, which provides the framework for efficient prediction, sampling, and delineation of contamination. To achieve this understanding, a multidisciplinary team is assembled to direct the investigations, using a dynamic work plan and emphasizing innovative field approaches.

Estimating the Phase Distribution and Mass Transfer of Organic Contaminants in Subsurface Environments

Michael G. Ellerd, Montana Department of Transportation; and William T. Brown, Energy Laboratories, Inc. (INDOOR)

This workshop will provide practitioners with the fundamentals to estimate the mass transfer and resulting phase distribution of organic chemicals in subsurface environments using minimal site investigation information and data.

It will present the principles of partition (solution/dissolution and volatilization/condensation) and sorption (absorption) of single and multiple component LNAPLs and DNAPLs, how these principles can be used to estimate the phase distribution of organic contaminants of soil and ground water samples, how to estimate mass transfer as conditions change in the subsurface, and how to evaluate the potential effectiveness and efficiency of various in-situ remediation methods such as vapor extraction and air sparging systems.

Surface Geophysics (Beyond locating drums, ESTs, and landfills)

Pieter Hoekstra, Bart Hoekstra, and Bob Grimm, Blackhawk Geometrics (Part I - INDOORS, Part II - OUTDOORS)

Unlike past geophysical workshops, this workshop will address deeper objectives involving ground water exploration, and mapping geologic features impacting contaminant migration, and geotechnical and environmental engineering. The focus will be on case histories and methods used in ground water exploration; mapping geologic features influencing ground water flow and contamiant migration; and mapping geotechnical parameters influencing remediation design of slurry walls, evaluating clay and sand gravel borrow pits, depth to rock competency, faults and shear zones in rock.

Single-Well, "Push-Pull" Test for Site Characterization

Jonathan D. Istok, Michael Hyman, Martin Schroth, and Mark D. Humphrey, Oregon State University (INDOOR)

This workshop will introduce participants to a new partical site characterization technology, the single-well "push-pull" test that can be used to measure a variety of aquifer properties in the field. The "push-pull" test method is a relatively simple extension of existing aquifer testing technolgies (slug tests and pumping tests) that requires only a small amount of additional effort and yet can provide useful information for remedial design and feasiblity assessment at low cost. The method is relatively simple and fast, with a typical test requiring less than one day of field work. The emphasis in this workshop will be on applicaitons of the method to quantitative determination of in-situ microbial activities related to intrinisc and enhanced bioremediation. Data from cast studies are used to illustrate each step of a "push-pull" test from test design to data analysis. Video tape clips of actual push-pull tests will be used to further illustrate field procedures.

U.S. EPA Soil Screening Guidance Workshop

David M. Kargbo, U.S. EPA; and Stephen J. Scott, Unvironmental Graphics, Inc. (INDOOR)

This workshop will cover details of the 7-step methodology in assessing risk-based soil screening levels (SSLs) for major environmental pathways of concern including ingestion, inhalation of volatile contaminants, inhalation of fugitive dust and migration to groundwater. Derivation of and rationale for the mass balance equations for each pathway will be discussed. The use of Data Quality Objectives and Data Quality Analysis in the development of SSLs will be addressed in detail as well as recommended methods for generating input parameters into the mass balance equations.

Buck Rogers, Project Manager: Satellite and Laser Technologies for Computerized Mapping and GIS Data Collection

John H. Kramer, Condor Earth Technologies, Inc.; and Jeff Schuyler, Applied Geochemical Inc. (INDOOR)

This workshop will help you to appreciate the power, utility and disadvantages of computerized field data collection systems, to understand global positioning systems (GPS) and appreciate applications of each. In a society where golf carts calculate the distance to the pin using satellites, consultants and environmental project managers who don't understand and use these technologies will be left behind.

Treatment Technology

Evan K. Nyer, Geraghty & Miller, Inc. (INDOOR)

Attendees will enjoy this seminar based upon the articles written in groundwater Monitoring and Remediation. Several new technologies will be discussed with field data reviewed, plus an analysis of the technical trends in the remediation field.

Introduction to Horizontal Environmental Wells

Daniel Oakley, Horizontal Technologies Inc.; and Dawn Kaback, Colorado Center for Environmental Management (INDOOR)

A recent survey illustrates that the number of yearly horizontal well installations has seen explosive growth during the last 3 years. During the late 1980's yearly installations numbered in the single digits. Yearly installations now number in the hundreds. The primary objectives of this workshop are to review the evolution of this industry concentrating on unique attributes of horizontal well that have led to more widespread use for remediation. Attendees will become familiar with the advantages and disadvantages of this emerging remediation method. Case studies will emphasize practical experience and lessons learned from different installations throughout the country.

Design, Installation, and Operation of Groundwater Injection and Infiltration Systems: It's Not for the Faint-Hearted

John Sciacca and Bruce Manchon, International Technology Corporation (INDOOR)

Injection/infiltration is being considered on an increasing basis for effluent disposal for ground water remediation systems. It is a technically complex process with many problems and not many professionals have experience with such systems. This workshop will provide an overview of many of the factors which need to be considered by attendees when they evaluate, design, install and operate their own systems. You will be shown actual examples from working systems with several interesting problems. You will understand the basic hydraulics of injection/infiltration systems (they don't behave the same as ground water extraction systems); the causative factors reducing or inhibiting injection/infiltration; become familiar with some of the basic maintenance, rehabilitation techniques, and regulatory requirements affecting the construction and operation of such systems; and more.

Practical Efficient Ground Water Sampling

David Kaminski, QED Ground Water Specialists; David Nielsen and Gillian Nielsen, Nielsen Ground Water Science, Inc.; and Michael J. Barcelona, University of Michigan (OUTDOOR)

Ground water sampling procedures in support of detection, assessment and remediation performance efforts have maintained their importance over the years. In some respect, these procedures have been reduced to rote mechanical exercises following regulatory guidance manuals. This may be useful in collecting consistent data of known quality if guidance is followed carefully. However, many of the procedural manuals are out-of-date or at odds with advances reported in the scientific literature. The continued use of bailers in well that could yield sufficient water for controlled purging and sampling with pumps is a clear example of poor, (i.e. inconsistent) albeit tolerated sampling practice.

This workshop will clearly discuss: selection of reliable sampling devices, their proper usage, and streamlined field analysis and water sample collection methods. The participants will gain a renewed perspective on sampling efforts as well as the means to conduct "value-added" field operations. The critical aspects of low-flow (minimal-drawdown) purging and sampling methods will be covered in detail. These efficient methods and related approaches can provide more defensible high quality datasets and assist in the interpretation of site-wide ground water conditions.

Borehole Geophysical Techniques for Detecting and Characterizing Fractures

Hughbert Collier, Tarleton State University (INDOOR)

Significant advances have been made in detecting and characterizing fractures in uncased well bores with borehole geophysical instruments. This workshop will review the principles, applications and limitations of both state-of-the-art and older technology. Several case histories will be presented and attendees are encouraged to bring their problem logs and questions. The course is designed for ground water scientists and engineers with any level of expertise in logging techniques.
