Abstract
The City of Lawrenceville uses a high yield well located in Rhodes Jordan Park to supplement its drinking water supplies. This area has been investigated by the U.S. Geological Survey, the University of Georgia, and the City of Lawrenceville since 1994 to identify the fracture system and recharge to the well. This study reports on gas tracer tests that provide additional insight into the natural flow field at the site. The tracer experiment involved diffusing krypton gas into a bedrock observation well on-site and monitoring the response of krypton in the production well. This procedure was performed using bedrock observation wells situated in different directions from the production well. The results indicate that a larger fracture aperture exists in the direction that is at right angles to the regional strike.
