Title: Hydraulic properties of rock units and chemical quality of water for INEL-1: a 10,365-foot deep test hole drilled at the Idaho National Engineering Laboratory, Idaho

Technical Report ·
OSTI ID:5487149

A 10,365-foot deep test hole drilled at the INEL (Idaho National Engineering Laboratory) in southeastern Idaho provided hydraulic information for rock units underlying the Snake River Plain aquifer. Four aquifer tests showed that the hydraulic conductivity decreased with depth - from an average of 0.03 feet per day for the interval from 1511 to 2206 feet below land surface to an average of 0.002 feet per day for the interval from 4210 to 10,365 feet. In contrast, the hydraulic conductivity of the Snake River Plain aquifer ranges from 1 to 100 feet per day. The hydraulic head increased with depth; the head at depth was about 115 feet greater than that for the Snake River Plain aquifer. Water temperature in the test hole increased from 26/sup 0/C (Celsius) at 600 feet below land surface to 146/sup 0/C at 9985 feet. The gradient was nearly linear and averaged about 1.3/sup 0/C per one-hundred feet of depth. Water from the Snake River Plain aquifer contained 381 milligrams per liter of dissolved solids and had a calcium bicarbonate chemical composition. The dissolved solids concentration in underlying rock units ranged from 350 to 1020 milligrams per liter and the water had a sodium bicarbonate composition.
