TABLE II
SUMMARY OF CALCULATED HYDRAULIC CONDUCTIVITY OF BEDROCK
GEISERT GRAVEL PIT
SLURRY WALL DESIGN
GREELEY, COLORADO
111025 -000
Notes:
Increasing MGP
MGP = calculated maximum gage pressure
cm /sec = centimeters per second
No Take; indicates that the hydraulic conductivity was too low to be measured by the test method.
Test boring LHP -4(B) was not conducted due to a faulty packer.
• Test conducted in weathered bedrock
** erratic data, not considered in calculations
