Unique Well Rehabilitation at Myrtle Beach AFB

Abstract
After only 10 weeks of operation, the efficiency of a small 3-well groundwater extraction system was significantly decreased. Yields were decreased by 40 to 50 percent. Severe iron and microbiologic fouling were the causes. Various mechanical adjustments were made with no noticeable effects. Finally, a unique well redevelopment and discharge line cleanout program (liquid and solid carbon dioxide) was implemented. This was followed by retrofitting a chemical injection metering system in two of the three extraction wells. The system has been operational for the last six months, and pumping rates have remained at or near their design rates.

The January meeting of the ETGS and the The East Tennessee Chapter of AIPG was conducted in Oak Ridge at Ryan's Family Steakhouse. Annett Sullivan presented her work at Peru Creek, a mine-affected stream located in the Colorado Rocky Mountains. Here three different processes were found to control cycling of element concentrations, which can vary significantly over the 24-hour (diel) timescale. Understanding the processes that control these cycles is important for environmental regulators and scientists who sample sites over longer periods of time. For instance, if a study involves one water sampling per day, then diel concentration cycles could introduce significant scatter into that dataset. The timing and controlling processes of these short-term cycles can differ, depending on chemical, physical and biological conditions.

TENNESSEE AND TENNESSEANS IN GEOTIMES
by J. Brad Stephenson
In the January 2001 issue of Geotimes, Tennessee and a Tennessean figure prominently in separate reports on sedimentology and careers in planetary geology.
In Mighty Mississippi meets New Madrid, staff writer Laura Wright reports on a GSA presentation regarding the impact of the Reelfoot Scarp on sedimentation and channel morphology in the Mississippi River. As a result of the 1811-1812 New Madrid earthquakes, the region upstream of the Reelfoot Scarp was depressed 8 to 11 meters. Changes in the river cross section are noted where it crosses the scarp, and the river is still interpreted to be adjusting to the sudden changes induced nearly two centuries ago.
