AbstractThe University of Arizona produces different types of radioactively contaminated waste. It is shipped to a burial site located on the Oracle Agricultural Center in Pinal County, Arizona and disposed of in shallow pits. This study dealt with water movement at the disposal site. Monitoring of water movement through young pits was accomplished with a neutron probe. It was found that due to slumping and cracking of the pit cap, the younger pits were very susceptible to greater than normal water infiltration. Further data were gathered around the older pits by deep soil sampling for tritium activity. Water fluxes and travel times to the major aquifer were calculated from these data. Estimates of travel times range from 40 to 230,000 years to reach the principal aquifer at 150 m.

Theoretical and field studies of fluid flow in fractured rocksHsieh, P. A.(Paul A.); Neuman, Shlomo P.; Bredehoeft, John D.; Simpson, Eugene S.; Maddock III, Thomas; Daemen, Jaak J.; Glass, Charles E. (The University of Arizona., 1983)A comprehensive methodology of hydraulic testing in fractured rocks is presented. The methodology utilizes geological and geophysical information as background. It consists of conventional single-hole packer tests in conjection with a newly developed cross-hole packer test. The cross-hole method involves injecting fluid into a packed-off interval in one borehole and monitoring hydraulic head variations in packed-off intervals in neighboring boreholes. Borehole orientation is unrelated to the principal hydraulic conductivity directions which, therefore, need not be known a priori. The method yields complete information about the directional nature of hydraulic conductivity in three dimensions on a scale comparable to the distance between the test boreholes. In addition to providing all six components of the hydraulic conductivity tensor, the cross-hole method also yields the specific storage of the fractured rock mass. While the theory behind this method treats the rock as a homogeneous, anisotropic, porous medium, the test provides detailed information about the degree to which such assumptions may actually be vaild in the field. The method may also be useful as a tool for detecting, in the vicinity of the test area, major fractures or faults that have not been intercepted by boreholes. Preliminary results from a granitic site near Oracle in southern Arizona are presented together with details of the instrumentation designed and constructed specifically for that site.
Structural, hydraulic, and geophysical properties of granite near Oracle, ArizonaJones, Jay W.; Simpson, Eugene S. (The University of Arizona., 1983)A combination of geophysical and hydraulic testing was conducted in granite near Oracle, Arizona. The purpose of the work is to determine relationships, if any, among fracture distribution, geophysical, and hydraulic properties of low permeability fractured rock. Neutron, gamma, acoustic velocity, electrical resistivity, and acoustic televiewer logs, and the results of over 100 single-hole straddle-packer injection tests were used to describe the fracture system. The geophysical techniques are sensitive to both subtle variations of the granite and to the fracture network. Fracture densities determined by the acoustic televiewer over hydraulically tested intervals do not correlate with measured hydraulic conductivities for the intervals. However, a strong correlation was noted between the neutron log response and measured hydraulic conductivities and used to estimate hydraulic conductivity in areas that were not hydraulically tested. A map of hydraulic conductivity was also constructed using the geostatistical technique of kriging.
Analysis of divergent flow tracer tests in fractured granite, near Oracle, ArizonaAikens, Alan William,1958-; Neuman, Shlomo P. (The University of Arizona., 1986)A computer model is extended and applied to analyze divergent flow tracer test data from a field experiment near Oracle, Arizona. The model can accommodate a pulse, step increase, and an arbitrary distribution of injection concentration with respect to time. The model is tested against three analytical solutions and is subjected to sensitivity analyses. The model is free of numerical dispersion with proper grid spacing and location of the external boundary. Analysis of field data using the model involves a curve matching procedure. An equivalent radial flow field is used to account for non-radial flow conditions by adjusting the flow rate and the mass that enters the flow field. Application of the model to field data yields a longitudinal dispersivity of 5.08 meters and a product of effective porosity and thickness of 0.009 meters. Since the test was not conducted under strict flow conditions, the above results are considered tentative.
