[CPEO-MEF] ITRC Offers More Internet Training Courses

[CPEO Moderator <cpeo@cpeo.org>]

[These ITRC internet training courses are open to anyone with interest 
in the learning more about the appropriate evaluation/implementation of 
innovative environmental technologies.  This is a particularly effective 
way for public stakeholders to learn about new and emerging 
technologies.  --Aimee]

The Interstate Technology and Regulatory Cooperation (ITRC) in 
conjunction with the EPA Technology Innovation Office offers a wide 
variety of internet training events on innovative environmental methods 
and technologies.  The upcoming "no cost" ITRC Internet Training topics 
are:

(1)  Enhanced In Situ Bioremediation of Solvents in Ground Water
DATE:  May 29th - Tuesday (2:00 p.m. - 4:00 p.m. EASTERN) 
Enhanced In Situ Bioremediation systems designed to remediate 
chlorinated solvents in groundwater involve input of an organic source, 
nutrients, electron acceptors, and/or microbial cultures to stimulate 
degradation. EISB systems may be used to remediate high concentrations 
areas within plumes or source areas, to help provide containment of a 
chlorinated solvent plume, or as part of a treatment train down gradient 
from a primary cleanup or containment system. 

This training is designed to introduce state regulators, environmental 
consultants, site owners and community stakeholders to the document 
created by the ITRC's In Situ Bioremediation Technical Team and the 
Remediation Technologies Development Forum (RTDF) Bioremediation 
Consortium titled, "Technical & Regulatory Guidance for Enhanced In Situ 
Bioremediation of Chlorinated Solvents in Ground Water". The training 
focuses on a variety of amendments, which may be added to in situ 
bioremediation systems, the mechanism of delivery and regulatory issues 
associated with approving or permitting EISB systems. You will also hear 
discussions of common problems encountered during operation of a system.
 
(2)  Permeable Reactive Barriers for Chlorinated Solvent, Inorganic, and 
Radionuclide Contamination
DATE:  May 31st- Thursday (11:00 a.m. - 1:15 p.m. EASTERN)
 
This training is designed to introduce state regulators, environmental 
consultants, site owners and community stakeholders to three documents 
created by the ITRC's Permeable Reactive Barrier Walls Technical Team 
and the Remediation Technologies Development Forum (RTDF) Bioremediation 
Consortium titled, "Regulatory Guidance for Permeable Barrier Walls 
Designed to Remediate Chlorinated Solvents", "Regulatory Guidance for 
Permeable Reactive Barriers Designed to Remediate Inorganic and 
Radionuclide Contamination" & "Design Guidance for Application of 
Permeable Barriers to Remediate Dissolved Chlorinated Solvents". The 
training focuses on the basic information one needs to determine and 
document the conditions necessary to effectively apply a permeable 
reactive barrier to a contaminated zone to be an effective part of 
remediating chlorinated solvents, radionuclides and other inorganic 
compounds in ground water. It provides a framework, that is, how to 
think about permeable reactive barriers based on science. The 
information contained in this manual and presentation is based on 
research activities of the RTDF and from experience and knowledge of the 
participating members.
 
(3)  Passive Diffusion Bag Samplers for Volatile Organic Compounds in 
Ground Water
DATES:     June 12, 2001 - Tuesday (2:00 p.m. to 4:00 p.m. EST)
                June 14, 2001 - Thursday (11:00 a.m. to 1:00 p.m. EST)
Passive diffusion bag (PDB) samplers are a simple and inexpensive way to 
sample ground water monitoring wells for a variety of volatile organic 
compounds. A typical PDB sampler consists of low-density polyethylene 
lay-flat tubing that is filled with distilled, deionized water and heat 
sealed at both ends. The bags are suspended in the monitoring well at 
the target horizon by a weighted line and allowed to equilibrate with 
the surrounding water (typically 2-weeks). The PDB samplers are 
retrieved from the well after the equilibration period and the enclosed 
water is immediately transferred to appropriate sample containers for 
analysis [40 ml VOC vials]. Field-tests show good correlation between 
samples obtained with PDB samplers and samples obtained using 
traditional methods (i.e. purge 3-5 casing volumes and sample with a 
bailer). Currently, the samplers are recommended only for long-term 
ground water monitoring of VOCs at well-characterized sites. The number 
of sites where they can be appropriately deployed is large and the 
associated cost savings are significant.

The ITRC internet training for this technology will discuss the 
technical and regulatory considerations associated with deployment of 
diffusion samplers, and summarize major points of the recently issued 
USGS document “Users Guide For Polyethylene-Based Passive Diffusion Bag 
Samplers To Obtain Volatile Organic Compound Concentrations In Wells,” 
which was developed in cooperation with the ITRC Diffusion Sampler Work 
Group.
