From introduction: This report summarizes existing subsurface data concerning the thickness, character, and structure of upper Permian evaporites in part of Eddy County, N. Mex. The area of particular interest lies in central eastern Eddy County between Project Gnome site, in the center of sec.

Abstract: A large amount of water leaks through the floor of Lake McMillan to underground solution channels or openings in the gypsiferous Seven Rivers Formation.

From abstract: The U.S. Atomic Energy Commission, through the Office of Test Operations, Albuquerque Operations Office, plans to detonate a nuclear device in a massive salt bed 1,200 feet beneath the land surface. The project, known as Project Gnome, is an element of the Plowshare program--a study of peacetime applications of nuclear fission. The location of the proposed underground shot is in a sparsely-populated area in southeastern Eddy County, N. Mex., east of the Pecos River and about 25 miles southeast of the city of Carlsbad.

From introduction: The present investigation is an attempt, by means of detailed areal mapping, to resolve the relations of the shelf-rock units to one another and to the reef and basin rocks and to clarify the confusing stratigraphic nomenclature.

From abstract: For Project Gnome, part of the Plowshare Program to develop peaceful uses for nuclear energy, a nuclear device was detonated December 10, 1961, underground in rack salt of the Permian Salado Formation southeast of Carlsbad, New Mexico. The Geological Survey's investigations on behalf of the U.S. Atomic Energy Commission provided basic geologic and geophysical information needed to define preshot and postshot geologic and hydrologic conditions at and near the site. This report describes the geology of the site, some physical and chemical properties of the rocks, and the known effects of the nuclear detonation on the rocks of the site.

From abstract: Drilling at the Project GNOME site, which is in the approximate center of sec. 34, T. 23 S., R. 30 E., NMPM, was undertaken in August and September 1958 by the W-W Drilling Company. The purpose of drilling this hole, which is at the precise location of the proposed shaft, was to determine (1) the lithologic and water-bearing characteristics of the rocks of Cenozoic, Mesozoic, and Paleozoic age that lie above the salt-bearing sequence in the Salado formation; (2) the depth to the top of the unleached salt and associated evaporites in the Salado formation; and (3) the local details of the salt-bearing sequence in the Salado formation.

From abstract: This report presents details of two test holes which were drilled to determine ground-water conditions in the near vicinity of the nuclear shot point.

From purpose and scope: This report discusses the ground-water systems and the interpretation of test results in the water-bearing zones above and below the proposed facility, Waste Isolation Pilot Plant (WIPP) in Los Medanos.

From introduction: This report contains geohydrologic and water-quality data, hydrologic testing methods, and preliminary interpretations related to the site area and it supplements a report in which the regional hydrogeologic regime was described (Mercer and Orr, 1977).

From introduction: The U.S. Geological Survey is participating in this evaluation by developing information on the ground-water hydrology of the region, obtaining geologic borehole data, and conducting hydrologic tests in boreholes on and near the WIPP site. This report provides well-construction information and lithologic data about the Rustler and Salado Formations and the top of the salt interval within the Salado Formation at the H-8 borehole complex.
