This report presents preliminary results and description of hydrologic testing activities for the Middle Sentinel Bluffs flow top (2,981-3,020 feet) at Borehole RRL-2. Hydrologic tests conducted include four over-pressure pulse, one constant head injection, and one slug injection test. Preliminary results indicate an observed hydraulic head for the test interval of 398.8 feet above mean sea level. Transmissivity values determined from hydrologic tests performed range between 9.3 {times} 10{sup {minus}3} to 6.2 {times} 10{sup {minus} 2} ft{sup 2}/day, with an assigned best estimate of 4.2 {times} 10{sup {minus}2} ft{sup 2}/day. The best estimate of equivalent hydraulic conductivity, based on an effective test thickness of 19 feet, is 2.2 {times} 10{sup {minus}3} ft/day. 8 refs., 10 figs., 4 tabs.
