Expandable Membrane Ground Anchors In Talus, United States Department Of Transportation, Federal Highway Administration

Dams

Expander Body (EB) tieback anchors were installed in talus material in Glenwood Canyon and evaluated as to their ease of installation and performance. The EB consists of a steel tube with thin, folded walls which is expanded in the soil by injection of cement grout. The EB system can be expanded in coarse, angular materials at high pressure without rupturing. It, therefore, can be successfully used to limit grout take in permeable materials.

Based on the results of this study, the EB system was approved as a permanent anchoring method in construction of I 70 through Glenwood Canyon.

Application Of Bmp For Prevention Of Ground-Water Contamination, Majid Ehteshami, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

The use of pesticides is an integral part of today's agriculture. In many cases, pesticides safeguard crops from severe pest infestation, or increase yield by suppressing competing weed growth. Pesticides often make the difference between profits and losses in farming operations. However, pesticides, even in extremely low concentrations, can pose a risk to human health and to the environment. Applied to plant or soil surfaces, or injected into the soil, pesticides may leach to the ground water or may be washed off with surface water. Pesticide contaminated surface water can reach ground water, or contaminated ground water can reach the …

Bioremediation Of Contaminated Surface Soils, J. L. Sims, R. C. Sims, J. E. Matthews

Reports

Biological remediation of soils contaminated with organic chemicals is an alternative treatment technology that can often meet the goal of achieving a permanent clean-up remedy at hazardous waste sites, as encouraged by the U.S. Environmental Protection Agency (U.S. EPA) for implementation of The Superfund Amendments and Authorization Act (SARA) of 1986. Bioremediation is consistent with the philosophical thrust of SARA, for it involves the use of naturally occurring microorganisms to degrade and/or detoxify hazardous constituents in the soil at a contaminated slip to protect public health and the environment.Bioremediation of contaminated soils, including applications and limitations, has been addressed.
