Incremental sampling (also call
“Multi-increment Sampling®”) is quickly gaining
recognition as a potentially useful technique to
increase sampling coverage of soil sites, while at the
same time reducing analytical costs. However, a number
of concerns and questions are also arising about how to
use incremental sampling in some scenarios, such as risk
assessment and action level compliance decisions that
have traditionally relied on upper confidence limit
(UCL) calculations. This course will cover the variety
of implementation options that are available for
incremental sampling that can address such concerns in a
site-specific manner.
For example, there are actually two
ways that incremental sampling can be used: 1) for the
derivation of an average over a decision unit; and 2)
for searching for contaminated areas. Incremental
sampling can also be integrated into other, more
traditional, sampling designs to improve their
performance.
An infrequently used, but highly
useful, sampling design is “stratified sampling.” Don’t
be confused! This "stratification" does not refer to
geologic soil strata. It refers to a statistically based
sampling design that is conceptually easy, but extremely
useful. The purpose of the design is to determine the
average concentration and UCL of an analyte across a
decision unit.
What
is special about a stratified sampling design is its
ability to weight for spatial size differences between
different sampling units within the decision unit.
Terms and concepts will be explained
in the course, along with how stratified and incremental
designs can be combined with real-time technologies to
create powerful data collection and analysis strategies.
#2 - Assessing Vapor Intrusion at Petroleum Release
Sites

This workshop will provide guidance on assessing
hydrocarbon vapor migration up through the vadose zone
and intrusion into structures. A conceptual model
of the typical vapor intrusion scenario will provide the
basis for a detailed discussion of the principles of
vapor migration and attenuation, including
biodegradation. Mathematical modeling approaches
addressing diffusion, mixing, advective flow, sorption,
and degradation will be presented. A number of
case studies of natural attenuation will be presented,
providing field data and demonstrating predictable vapor
attenuation given sufficient soil thickness and oxygen.
Sampling considerations and lessons learned from vapor
intrusion investigations will also be offered.
#3 –
BioVapor, a 1-D Vapor Intrusion Model with Aerobic
Biodegradation
Tom
McHugh, GSI,
Houston, TX
George DeVaull, Shell Global Solutions,
Houston,
TX
Kevin Hale, New York Department of Environmental
Conservation, Albany, NY
This
workshop will introduce API’s BioVapor 1-D vapor
intrusion model. The model assesses vertical vapor
transport by advection and diffusion, assuming
first-order aerobic biodegradation. The model
calculates indoor air concentration and associated risk,
as well as concentration vs. depth profiles.
The workshop will provide a basic overview, software use
demonstration, and subsequent demonstration of a number
of example case studies.
#4 – preregistration is required; no walkins
The MCP Audit 2009 - A Case Study Approach: Training
Materials
Paul Locke, MassDEP, Boston, MA, Lisa Alexander, MassDEP,
Boston, MA, John Zeigler, MassDEP Western Regional
Office, Mike Reed, MassDEP Western Regional Office
This
year's Audit Case Study Training will focus on reviewing
one case study in depth concentrating on site
activities at this former plating facility from Phase
III through Phase V. The first hour of the course
consists of at-home review of the Phase II Report to get
an overview of the site issues and the completion of a
questionnaire provided by MassDEP.
"Homework" - To be Completed Prior to Seminar Date:
Review the Phase II Report
Complete the MassDEP 2009 Audit Case Study Questionnaire
(last page of PDF file). There are no right or wrong
answers for this particular case, but please come to the
training prepared to:
Briefly discuss the conceptual site model; and, Make
independent suggestions for possible Remedial
Alternatives that could be considered for the site.
As stated by the LSP Board Course Approval Letter: LSPs
must present the course provider proof of homework
completion prior to attending course # 1207-09. If
unable, the Board requests no Continuing Education
Credits for the course. Therefore, please complete the
questionnaire, in writing, and bring it with you to the
seminar to be handed in at registration.
#5 - Environmental Fate of Hydrocarbons in Soils and
Groundwater
James Dragun, Ph.D., The Dragun Corporation,
Farmington Hills, MI
This
course will cover predicting
bulk hydrocarbon migration, the extent of
absorption of organic chemicals, chemical volatility in
soil, organic chemical reaction rates and rates of
organic chemicals in soils.
The information will be presented in the context
of site remediation, site disposal facilities, and
analyzing chemical releases, as well as auditing
closures of industrial facilities.
