Jerry W. Mercer Kevin F. Dennehy 1982 <p><span>Data were collected during hydrologic testing at wells H-5A, H-5B, and </span><span>H-5C in the northeastern part of the proposed Waste Isolation Pilot Plant </span><span>site in southeastern New Mexico. The three water-bearing zones tested, the </span><span>Magenta and Culebra Dolomite Members of the Rustler Formation and the Rustler </span><span>Formation-Salado Formation contact, yield water to wells at rates less than </span><span>0.6 gallon per minute. Throughout the testing, water-pressure response in </span><span>the tested zone was monitored by a pressure-transducer system. Shut-in and </span><span>slug tests were conducted to acquire data from which the following values </span><span>were derived.</span></p><p><span>Dissolved-solids concentrations In water samples were: (1) Magenta Dolomite Member, 6,090 milligrams per liter; (2) Culebra Dolomite Member, 144,000 milligrams per liter; and (3) Rustler Formation-Salado Formation contact, 412,000 milligrams per liter. The major chemical constituents of water samples from the Magenta Dolomite Member were sodium and sulfate; from the Culebra Dolomite Member, sodium and chloride; and from the Rustler Formation-Salado Formation contact, magnesium and chloride. Radium-226, a naturally occurring radioactive element, was present in samples from all three zones. </span></p> application/pdf 10.3133/wri8219 en U.S. Geological Survey Results of hydrologic tests and water-chemistry analyses, wells H-5A, H-5B, and H-5C, at the proposed Waste Isolation Pilot Plant site, southeastern New Mexico reports
