Abstract

Data were collected during hydrologic testing at wells H-5A, H-5B, and H-5C in the northeastern part of the proposed Waste Isolation Pilot Plant site in southeastern New Mexico. The three water-bearing zones tested, the Magenta and Culebra Dolomite Members of the Rustler Formation and the Rustler Formation-Salado Formation contact, yield water to wells at rates less than 0.6 gallon per minute. Throughout the testing, water-pressure response in the tested zone was monitored by a pressure-transducer system. Shut-in and slug tests were conducted to acquire data from which the following values were derived.

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.
