The Investigation of Potential Microbiologically Induced Corrosion (MIC)
of Stainless Steel Monitoring Well Components
at the Y-12 Plant, Oak Ridge, Tennessee
Monitoring wells are constructed from a variety of materials
from Polyvinyl Chloride (PVC) to various grades of steel.
Stainless steel is favored due to its durability and resistance
to corrosion. At the Y-12 Plant, a majority of the wells are
constructed from stainless steel, and elevated levels of nickel
and chromium concentrations not associated with known contaminant
source areas have been observed in a number of them. These trace
metals comprise approximately 30% of the alloy to make stainless
steel. Corrosion of the casing and screen and subsequent
dissolution of nickel and chromium is suspected. However, the
water quality data from wells exhibiting an increase in nickel
and chromium do not tend to support the possibility of chemical
corrosion. However, the water quality data and borehole camera
surveys performed at several wells, potentially agree with
corrosion from a microbiological source.
Microbiological Induced Corrosion (MIC) is a recognized source of stainless steel failure in the nuclear industry. With the right environmental conditions, it is possible for bacteria to thrive in a monitoring well, attached to the well casing and screen. Through biochemical processes, these organisms are able to corrode stainless steel causing the dissolution of the component metals. At the U.S. Department of Energy Y-12 Plant, an investigation into the viability of this process as a source for nickel and chromium in monitoring wells is underway.

The March meeting was held in conjunction with a
"brown-bag" seminar at IT Corporation in Knoxville.
ETGS member Tom Zondlo presented Applications of Thermal
Infrared Surveys at Redstone Arsenal. (An abstract is
available in the March
Newsletter.) In his case study, Tom discussed the application
and limitations of a thermal infrared survey as the first step in
a large-scale karst hydrogeologic investigation. He summarized
the objectives, methodology and preliminary results of the
survey, which has already resulted in the identification of
nearly 900 springs and seeps within the 40,000-acre study area.
ETGS thanks Tom for an excellent presentation.
Additional appreciation goes to ETGS member Mark Joop, as well as Bill Hedberg and Scott Logan for their roles arranging this joint meeting. The meeting was well attended by geologists from IT and elsewhere. Eight IT geologists have joined ETGS as a direct result of the March meeting, bringing the total number to twelve (so far). Thanks to everyone at IT Corporation for your support; and welcome, new members!
In addition to giving a brief description of the society for the benefit of our guests, we also discussed the upcoming bicycle field trip on the Virginia Creeper Trail. Tony Tingle is spearheading the effort to identify a trip leader, as well as lodging, camping, and bike-shuttle options. Tentatively, the trip will be held on May 20 or June 3. Please see Tony's article later in this issue for additional information.
Meeting attendees were reminded to submit suggestions for the "Name-the-Newsletter" contest. It was noted that only seven submissions had been received-all from the same member. (Since that time, one additional nomination has been received from a second person.) A call for membership renewal was also made, including a brief discussion about the forthcoming Membership Directory. (Please see Seaira's article later in this issue for details.)

ETGS is the primary organization serving the geological
community of East Tennessee. Its members ARE the organization.
Each member is a valuable resource with the potential to share a
unique set of experiences and talents with the rest of the group.
With each new member, ETGS increases its ability to keep local geologists informed about technical and professional trends in the geosciences, as well as opportunities for social interaction and networking. Unfortunately, many practicing geologists in East Tennessee are not members of the society and may not even be aware of its existence.
It has been suggested that we might increase awareness of ETGS among our colleagues by contacting Professional Geologists (PGs) registered with the State of Tennessee. Originally, it was thought that e-mail would be a cost-effective way to reach them. Although the State does not maintain e-mail addresses in its records, the names and addresses of Tennessee PGs may be downloaded from the Department of Commerce and Insurance web site (http://www.state.tn.us/cgi-bin/commerce/roster2.pl).
The online database includes nearly 3000 PGs, but only 800 of them live in Tennessee. Of these, 442 live in East Tennessee, loosely defined as the Cumberland Plateau eastward. Removing 70 who are already on the ETGS mailing list leaves 372 potential new members in the region.
For a total investment under $100, a computer-generated postcard can be sent to each of these 372 Professional Geologists for about $0.25 each (postage and paper). The cards could include a brief description of the society; list our web-site address; and invite the recipient to our next meeting. From a financial perspective, we would recover this investment if only 7 people (1.9%) join the organization for one year. More significantly, ETGS would benefit from the expertise and perspective of each added member.
This proposed recruitment effort will be discussed during the April meeting. If you have any suggestions or questions, please share them at the meeting or by contacting Membership Director, Jim Morgan (email@example.com), or Brad Stephenson (firstname.lastname@example.org). Finally, please help with this effort by inviting your friends and coworkers to our meetings and field trips. Visitors are always welcome!

This is your final chance to suggest the winning name for the
ETGS/AIPG Newsletter and receive a free, one-year
ETGS membership! The winning name will be selected
by a vote at the April meeting. Submit as many titles as you
like, but do it by Friday March 31, 2000.
E-mail your nominations to Brad Stephenson (email@example.com). You will be notified if any of your suggestions have been submitted previously.

Considerable interest has been expressed in a geology-oriented
bicycle trip on the Virginia Creeper Trail. However, I am still
looking for a person that would be willing to lead the proposed
field trip. Can you suggest someone versed in the stratigraphy of
that area? I have checked with a couple of folks that I know and
have had no success.
The proposed trip is a stratigraphic tour along the Virginia Creeper Trail. It would be an almost-all-downhill ride as long or as short as we would like to make it. A shuttle service would be used to transport the group to a high point (near Whitetop Station), and we would ride downhill toward Damascus. The Virginia Creeper starts in Abingdon and ends just east of Whitetop Station for a total length of 33.4 miles. It began as a Native American footpath and became part of the Virginia-Carolina Railroad system in 1907. Now it serves as a multi-use recreation trail.
Tentative dates for the trip were discussed at the March meeting. The weekends of May 20-21 and June 3-4 are currently the top choices, but the trip-leader search and other considerations may require that we schedule the trip for next autumn. Any suggestions for a trip leader (and/or alternative trip locations) should be directed to Tony Tingle at firstname.lastname@example.org.
