IGS geologists are offering classes and field
trips through the IU Bloomington Continuing
Studies Lifelong Learning program.
"Whose Fault Is It?
The Mt. Carmel Fault in Monroe and
Lawrence Counties" will take
place on Sept. 24 and Sept. 26. On
Thursday evening IGS geologists Brian Keith
and Todd Thompson will teach you how to
read the new geologic map of Monroe
County and to follow the trace of the fault on
the map; on Saturday you'll participate in a
field trip to look at exposures of the fault
along Highway 446.
As part of the "Issues and Experts" lunchtime programs, IGS geologist John Rupp will present "New Uses for an Old Fuel: Coal in Indiana's Future" on Oct. 7 at 12:15 at the Meadowood Retirement Community in Bloomington. Registration is required. |

On Sept. 19, the Lost River Conservation
Association is holding a public guided tour of
the Lost River Karst aquifer system,
beginning in Orleans, Ind.
Contact Bob Armstrong (317 253-6951) for
more information or to sign up for the trip.
Additional tours may also be arranged
through him.
And if you can't make it to the public tour, the
IGS has a guidebook that is
designed to be a self-guided trip of the
Spring Mill Lake and Lost River basins in
southern Indiana. Karst
Geology and Hydrology of the Spring Mill
Lake and Lost River Drainage Basins in
Southern Indiana is concerned
primarily with the
karst geology, hydrology, and water quality of
the area. It includes a road log describing
geologic features along the field trip route
from Indianapolis, Indiana, to Spring Mill
State Park near Mitchell in Lawrence County,
Indiana. An appendix details the driving
instructions for the entire field trip route.

In Indiana, the groundwater in many
agricultural areas is susceptible to pollution
from agricultural sources such as inorganic
fertilizers, crop residues, applied manure,
and manure from grazing cattle. Results
of an important environmental study by the
IGS on this
subject have been published in Best
Management Practices to Remediate Nitrate
Contamination in a Major Outwash Aquifer in
Jackson County, Indiana, IGS
Occasional
Paper 70, by D. Harper and E. Hartke.
This paper resulted from a 4-year field
experiment undertaken by the authors,
wherein they developed a cooperative effort
with local farmers and farm service
companies to establish a program to
implement best management practices
(BMPs) for the application of fertilizer. The
project involved intensive groundwater
monitoring with the intention of assisting
farmers with optimizing the rate, method,
and timing of their nutrient applications.
Ideally, these BMPs will result in minimizing
the
influx of nitrate into the local aquifer, which is
composed of glacial outwash and windblown
sands. The research and
recommendations are applicable to similar
aquifers of the same composition.

It's been a while since we updated you
on
staff changes at the IGS, and lately we've
welcomed quite a few new faces and said
goodbye to some old friends.
Our newest staff member is Paul Rohwer, Programmer and Database Administrator, recently of the IU Alumni Association. He is working on his Ph.D. from IU's School of Informatics and Computing. Prem Radhakrishnan previously held this position, but left to pursue private enterprise as part-owner of 39 Degrees North, a GIS consulting company. Michael Daniels is our new System Analyst/Programmer and Web Developer. He comes to us from IU's Kelley School of Business. Prior to that he was a Technology Consultant for IU's Technology Services. Michael received his Bachelor of Science degree in Informatics with a minor in Computer Science at IU Bloomington. He took over the position from Nathan Eaton, who recently moved on to a position as GIS developer at Indiana's National Guard at Camp Atterbury. Walter Gray is our new Education and Outreach Coordinator. Walt has considerable experience as a science teacher at the elementary, middle, and high school levels in both North Carolina and Indiana. In addition, he has organized and taught geologic field workshops in North Carolina and Wyoming. Walt is working on his master's degree in Geochemistry in IU's Department of Geological Sciences. Amzie Wenning, who previously held this position, left the Survey to pursue a career in financial management. David Jacob is the new Office and Field Assistant in the Subsurface Geology Section. He is replacing Rebecca Lowe, who decided to remain at home after the birth of her baby. David was most recently affiliated with ACM Engineering & Environmental Services and brings considerable experience as a laboratory technician to the position. Mary Parke, previously of Chevron and the University of California at Berkeley, is filling the new position of Petroleum Geologist. This is her return to Indiana after receiving her B.S. from IU; she also has a Ph.D. from Cornell University. Amongst her many accomplishments are breeding and showing championship Welsh Pembroke corgis. Shawn Naylor, who came to the Center for Geospatial Data Analysis 1½ years ago as Hydrogeologist, has been named the new Director of the Center. Sally Letsinger stepped down from this position to be able to spend more time on research and scholarly activities for the Center. Sam Frushour, Head of the Field Services Section, retired after nearly 25 years of service to the IGS. Sam is still devoting time to the Survey by working on a major publication about Indiana caves, which we hope to publish next year. Paul Irwin, GIS and Database Systems Analyst, recently retired after nearly 33 years of service to IU and the IGS. He is enjoying canoeing local waterways and working in his woodshop. His position will remain unfilled for the immediate future. John Comer, Head of the Geochemistry Section, retired after 20 years of service to the IGS. John is keeping his hand in by acting as editor for an upcoming volume of papers on environmental reclamation for the Survey. Jennifer Olejnik, Glacial Geologist, left the Survey last year in August to pursue life in northern Indiana and is, at present, staying home to spend more time with her children. |
