This year, as always, has been busy as I continue to teach Hydrgeology (GEOL 4003/6003) and Aqueous Geochemistry (GEOL 4007/6007). I am also continuing work on a three-year contract with the State of Georgia [EPD DNR GGS] which involves a study of the potential for salt-water intrusion into the upper Floridan aquifer in Camden County - Georgia's fastest growing county. As many of you know brackish water is found at the base of the Floridan aquifer in coastal Georgia and pressure reductions in the upper Floridan aquifer resulting from overexploitation of ground water resources can result in the upwelling of salt.

I am pleased to announce that Danielle Sheheen and Mindy Crean have successfully completed their M.S. theses under my direction. These two former students are now gainfully employed as hydrogeologists in the Atlanta region. Working with Dr. Ghazi we have determined that zinc is the most problematic of all the heavy metals found in Atlanta region stream flow. We have conjectured that the source of much of this zinc may be the erosion of automobile tires. Zinc concentrations along with other heavy metals increase notably during peak stream discharge. Heavy metal concentrations in urban stream flow are notably lower than in urban street runoff leading us to conclude that much of the metal load is sorbed onto suspended partilces present as turbidity. This will be the subject of ongoing studies. Danielle Sheheen's thesis study analyzed concentration-discharge relationships and from these finding we were able to analyze sources of water constituting stream flow here in the Atlanta region. Continued work is being done in this area. Our work has been presented at recent conferences and a summary article has been accepted for publication in Environmental Geology.

Dr. Elliott, myself, and four undergraduate students - Kris Spykes, Danette Cooper, Michelle Foster, and James Brewer - have been involved with a service and research project involving an urban wetland in Dekalb County near Medlock Park. The project is headed by Dave Butler, an alumnus of our department (B.S. 1991), who for years has been the President of the South Peachtree Creek Nature Preserve. Under Dave's supervision our group has installed monitoring wells at the Preserve in order to better understand the hydrology of this urban wetland - a home to many bird species and other fauna. We have also undertaken analyses of these soil underlying the site. We are essentially trying to better understand what keeps this wetland wet, which will give the neighborhood group better insight on how to care for this very valuable resource. The project has also led to several Senior Theses that this group of students have worked on jointly. These students should be commended for undertaking such a worthwhile and time consuming research/service project.

I have recently completed a study with Jake Peters of the USGS in Atlanta in which we compared and contrasted urban stream flow characteristics to those of less urbanized watersheds in the Atlanta metropolitan region and the Georgia Piedmont. It is widely known that urban streams peak faster and higher during storms; however, we determined that they are also characterized by faster recession periods and lower summer baseflow. They also apparently lose less water to evapotranspiration during the growing season (perhaps because they are so prolific in transmitting water during storm events). Our findings will be published soon in Hydrological Processes. As you can see these explorations are virtually endless and I wish I had more time just to do this work.
