- Rock core descriptors based on U.S. Bureau of Reclamation "Engineering Geology Field Manual, Volume I, Second Edition" (1998).- 6-inch diameter borehole advanced vertically into top of competent rock; 5-inch diameter PVC secondary casing cemented to bedrock; secondary seal allowed to cure >8 hours, seal evaluated and verified prior to coring activities.- Bedrock core collected using 94 mm wireline system with split inner barrel; cuttings removed with compressed air using potable water as necessary to control dust and cool bit; polycrystalline impregnated bit, flat kerf, surface (bit face) discharge. - Recovered rock cores measured 2.390 inches (60.706 millimeters) in diameter.- Measurements taken from top of sample-interval recovery (e.g., from the top of an individual core run).

Moderately hard (sample can be scratched with knife using light to moderate pressure) to hard (can be scratched with knife using heavy pressure). - Moderately Fractured (core recovered in lengths from 4 to 12 inches, with most lengths about 8 inches in length).- Fracture coatings range from very dark gray (10YR 3/1) to black (10YR 2/1). Fractures are mostly moderately open to open (1-10 mm). Fractures are oriented at 70-90 degrees from core axis.- Staining of core begins at the lower face of a fracture at 66.5 inches from top of run and extends downward to 73.5 inches below top of run; definite petroleum-type odor at 66.5 inches; stained interval is gray (10YR 5/1); lower boundary of staining is delineated in 3 mm vertical distance.- Elapsed drilling time = 53 minutes; penetration rate = 0.17 feet (2 inches) per minute.

From 21.0 to 27.0 feet, drilling return water did not have visual or olfactory evidence of petroleum, coal tar, or similar impacts. At 27.0 feet, drilling return water exhibited dark color, definite sheen, and definite odor.

- Analytical sample collected from rock core interval with stained appearance that began at a fracture face located at 66.5 inches of this core run. Rock core sample was collected from 4.0 inches above the top of the stained zone (sample ID = SBD2, 66.5FF-4.0"), from 1.5 inches below the top of the stained interval (sample ID = SBD2, 66.5FF+1.5"), and from below the stained interval (sample ID = SBD2, 66.5FF+10.5").

31 feet 0 inches to 36 feet 0 inches: - Limestone; massive. Colors in upper 32 inches range from light bluish gray (10B 7/) to bluish gray (5PB 6/); colors below 32 inches range from light gray (10YR 7/2) to brown (10YR 5/3). Moderately hard (sample can be scratched with knife using light to moderate pressure) to hard (can be scratched with knife using heavy pressure). - Core at top of run is curved.- Moderately Fractured (core recovered in lengths from 4 to 12 inches, with most lengths about 8 inches in length.- Upper 3 inches of core had slight but definite sheen. Remainder of core did not exhibit definite non-native staining or odor.- Fractures are not coated except for lowermost end of core at 63.5 inches, which was 50% coated very dark gray (10YR 3/1) to black (10YR 2/1).- From 0 to 16 inches, 40-50% pitted to 10 mm with a few vugs to 30 mm that have calcite crystals to 5 mm.

- At 31.5 inches, abrupt color change.- From 49 to 63.5 inches, 25-35% pitted to 5 mm.- Elapsed drilling time = 16.2 minutes; penetration rate = 0.3 feet per minute.

From 31.0 to 35.0 feet, drilling return water exhibited dark color, definite sheen, and definite odor. From 35.0 to 36.0 feet there was a noticable reduction in return water discoloration and associated odor.

- Analytical sample collected from top of core run where a sheen on rock core was observed. Analytical sample was collected from sheen zone at top of Run 3 (sample ID = SBD4, R3TOP +0.0") and from below interval of potential impact (sample ID = SBD4, R3TOP+30.5").


22 feet 0 inches to 31 feet 0 inches: - Limestone; massive. Colors in upper 32 inches range from light bluish gray (10B 7/) to bluish gray (5PB 6/); colors below 32 inches range from light gray (10YR 7/2) to brown (10YR 5/3). Moderately hard (sample can be scratched with knife using light to moderate pressure) to hard (can be scratched with knife using heavy pressure). - Moderately Fractured (core recovered in lengths from 4 to 12 inches, with most lengths about 8 inches in length.- Core, fractures, and/or fracture coatings do not exhibit definite non-native staining or odor.- Fractures are not coated.- From 32 to 51 inches, 25-35% pitted to 1 mm with a few pits to 4 mm.- From 68.5 to 75.5, 15-25% pitted to 4 mm.- Core at bottom of run is curved.- Elapsed drilling time = 29 minutes; penetration rate = 0.3 feet per minute.

From 22.0 to 28.0 feet, drilling return water did not have visual or olfactory evidence of petroleum, coal tar, or similar impacts. At 28.0 feet, return water had slight sheen, no odor. From 28.5 to approximately 29.5 feet, return water had slight sheen and slight odor.

-Analytical sample collected 13.0 inches from the bottom of core run (sample ID = SBD4, R3TOP-13.0"); sample selection was based on sheen observed at top of next core run.
