Use of 3H/3He Ages to evaluate and improve groundwater flow models in a complex buried-valley aquifer Use of 3H/3He Ages to evaluate and improve groundwater flow models in a complex buried-valley aquifer
Combined use of the tritium/helium 3 (3H/3He) dating technique and particle-tracking analysis can improve flow-model calibration. As shown at two sites in the Great Miami buried-valley aquifer in southwestern Ohio, the combined use of 3H/3He age dating and particle tracking led to a lower mean absolute error between measured heads and simulated heads than in the original calibrated...

Detection of underground voids in Ohio by use of geophysical methods Detection of underground voids in Ohio by use of geophysical methods
Geophysical methods are generally classified as electrical, potential field, and seismic methods. Each method type relies on contrasts of physical properties in the subsurface. Forward models based on the physical properties of air- and water-filled voids within common geologic materials indicate that several geophysical methods are technically feasible for detection of subsurface voids...

Evaluation of ground-water flow by particle tracking, Wright-Patterson Air Force Base, Ohio Evaluation of ground-water flow by particle tracking, Wright-Patterson Air Force Base, Ohio
The U.S. Geological Survey (USGS) and Wright-Patterson Air Force Base (WPAFB) began a Basewide Monitoring Program (BMP) in 1992. The purpose of the BMP was to establish a long-term ground-water and surface- water sampling network in order to (1) characterize current ground-water and surface-water quality; (2) describe water-quality changes as water enters, flows across, and exits Base...

Contributing recharge areas to water-supply wells at Wright-Patterson Air Force Base, Ohio Contributing recharge areas to water-supply wells at Wright-Patterson Air Force Base, Ohio
Wright-Patterson Air Force Base, in southwestern Ohio, has operated three well fields--Area B, Skeel Road, and the East Well Fields--to supply potable water for consumption and use for base activities. To protect these well fields from contamination and to comply with the Ohio Wellhead Protection Plan, the Base is developing a wellhead-protection program for the well fields. A three...
