“…Where secondary processes have been active, the Culebra is extensively fractured, forming a water-bearing unit with relatively high permeability. Hydrologic field studies first focused on the Culebra during preparations for the 1961 Project Gnome underground nuclear detonation approximately 12 kilometers southeast of the WIPP site Cooper and Glanzman, 1971). Because of its relatively high permeability in the vicinity of the WIPP site, the Culebra is considered an important potential pathway for the transport of radionuclides in the event of a repository breach (U.S. Department of Energy, 1980a, sec.…”

A series of analyses, including variable-density flow simulations, was used to examine groundwater flow in the vicinity of the Waste Isolation Pilot Plant (WIPP) in the context of the regional flow system. WIPP is an underground repository mined from a thick bedded-salt unit to provide a facility for the disposal of radioactive waste. WIPP is located in southeastern New Mexico. The analyses primarily examined the Culebra Dolomite Member of the Rustler Formation, which is a potential pathway for the transport of radionuclides to the biosphere in the event of a breach of the WIPP repository. An analysis of the relative magnitude of pressure-related and density-related flow-driving forces indicates that density-related forces are not significant at the WIPP site and to the west but are significant in areas to the north, northeast, and south of the site. The area to the south is important because it lies along potential transport pathways from the site. In this area, groundwater flow simulations based on equivalent-fresh water head produce very misleading information on predicted flow directions and velocity magnitudes. A regional-scale, variable-density model of groundwater flow in the Culebra Dolomite Member was developed in which a baseline, approximate steady-state simulation was calibrated to the distribution of equivalent-fresh water heads. The flow field from the baseline simulation, along with long-term brine transport patterns, indicates that flow velocities are relatively fast west of the site and extremely slow east and northeast of the site. In the transition zone between these two extremes, which includes the WIPP site, velocities are highly variable.

“…Although most investigators agree with the interpretation that a dissolution zone exists in the Rustler Formation at the WIPP site (Cooper and Glanzman, 1971;Powers et al, 1978;Mercer, 1983;Chaturvedi and Rehfeldt, 1984;Bachman, 1985;and Snyder, 1985), other investigators oppose this concept and think that the westward decease of halite within the Rustler simply represents depositional limits (Powers and Holt, 1984;and Holt and Powers, 1988).

This hydrogeologicmodeling study has been performed aspart of the regional hydrologiccharacterization of the Waste Isolation PilotPiVant(WIPP) sltein southeastern New Mexico.The studyhasproducedan estimation ofthe transmissivity and Darcy-velocity distributions in the CulebraDolomiteMember of the Permian Rustier Formationatthe WIPP site. The results ofthis studyareintendedtosupport SandiaNational Laboratories performance-assessment calculations. The three-dimensional finite-difference codeSWIFT IIwas employedforthe numerical modeling, usinga variable-fluid-density and single-porosity formulation. The spatial scale ofthemodel,21.3km by 30.6km, was chosento allow simulation ofregional-scale pumping tests conductedat t_he H-3 and H-11 hydropadsand theWIPP-13 borehole, which arelocated south,southeast, and northwest, respectively, ofthe centerofthe WIPP site. The modeledareaincludes and extends beyond thecontrolled areadefined by theWIPP-site boundaries.
