A Low Rise Hospital Development On Restored Opencast Fill, W. M. Kilkenny Jun 1988

A Low Rise Hospital Development On Restored Opencast Fill, W. M. Kilkenny

International Conference on Case Histories in Geotechnical Engineering

An extensive low-rise hospital development has taken place since 1982 on a former opencast coal mining site 30 years after working and restoration. The clay and shale fill some 20 metres deep was placed without systematic compaction. Five separate site investigations have been carried out at different times during the last 20 years and a detailed engineering geological mapping exercise was completed in 1977. Drainage works and the main buildings in Scheme 1 and 2 have been monitored during and after construction. Significant settlements have occurred requiring some remedial work. A surcharge and inundation trial has been undertaken prior to …


A Modified Field Infiltrometer Test For Clay Liners, G. S. Laird, W. B. Lozier, A. M. Gurevich Jun 1988

A Modified Field Infiltrometer Test For Clay Liners, G. S. Laird, W. B. Lozier, A. M. Gurevich

International Conference on Case Histories in Geotechnical Engineering

Regulatory agencies are looking more frequently to in situ field hydraulic conductivity tests for the assessment of a liner's compliance to a specified hydraulic conductivity. Most field tests have evaluated hydraulic conductivity by measuring the infiltration rate of the liner. The infiltration rate can be used to arrive at a hydraulic conductivity value if the hydraulic boundary conditions of the test can be identified or if the head loss at different depths can be measured. A test fill of a clay liner was evaluated for its saturated vertical hydraulic conductivity. This paper discusses the use of eight tensiometers to measure …


A Study Of Contamination Migration At A Hazardous Waste Facility In Louisiana, George H. Cramer Ii Jun 1988

A Study Of Contamination Migration At A Hazardous Waste Facility In Louisiana, George H. Cramer Ii

International Conference on Case Histories in Geotechnical Engineering

Traditionally clay soils have been regarded as being relatively impermeable to the migration of water and contaminants. Recent studies in Louisiana are beginning to show, however, that laboratory permeability tests are not true indicators of the ability of an in-situ soil to retain or transmit fluids. Both the depositional and post-depositional environment of a soil can greatly alter its in-situ permeability. In particular, post-depositional structural fractures provide preferential pathways for contaminant migration at rates that far exceed those predicted by using laboratory permeability values. Difficulties in field identification of these pathways reduces modeling of their effect on site hydrology to …


Complementing Radiologic Data With Geology – A Case History, Dennis Mcgrane Jun 1988

Complementing Radiologic Data With Geology – A Case History, Dennis Mcgrane

International Conference on Case Histories in Geotechnical Engineering

The goal in characterizing radioactively contaminated soil is to quantify the degree of contamination and its parameters. A cost effective, small scale characterization is done by performing a surface radiological survey with subsurface data coming from boreholes augered in a tight grid pattern. Confidence in the between-hole extrapolations depends on the grid size. However, at the widely contaminated site in Maywood, New Jersey a grid width of 100 feet was the only economical choice. Accurate contamination parameters were determined despite the wide hole spacings once geologists and health physicists learned how local geologic conditions controlled the contamination's location and extent. …


Control Of Uplift From Ground Water, R. V. Sarsby Jun 1988

Control Of Uplift From Ground Water, R. V. Sarsby

International Conference on Case Histories in Geotechnical Engineering

This paper relates to the conversion of a disused water reservoir into a landfill site for domestic and industrial refuse. The reservoir was initially subdivided into four cells (by using earth bunds) and three of the cells have been successfully prepared and filled. The fourth cell is the largest and presents the greatest number of geotechnical problems, the major one being the problem of ensuring that leachate does not escape into the groundwater. The first owner of the site removed natural clay from various parts of the reservoir base to seal the first three cells. In doing so he exposed …


Design And Construction Of A Soil Bentonite Slurry Wall Around An Operating Facility Superfund Site, A. S. Burgess, G. S. Laird, M. S. Leonard Jun 1988

Design And Construction Of A Soil Bentonite Slurry Wall Around An Operating Facility Superfund Site, A. S. Burgess, G. S. Laird, M. S. Leonard

International Conference on Case Histories in Geotechnical Engineering

A soil bentonite slurry wall was designed for an NPL site to stop further migration of chemicals in a complex aquifer system, and to facilitate the removal of possible chemical sources from saturated zones beneath the site. Pumping from within the slurry wall will maintain inward and upward hydraulic gradients and thus stop further lateral or vertical migration of chemicals from the contained area. The slurry wall was constructed under an exceptionally detailed Quality Assurance; Quality Control review by the Contractor and two independent consulting firms. Ground movements, vibration levels and opacity of dust produced during construction were monitored for …


Failure And Reconstruction Of A Waste Containment Pond Slope, Dorairaja Raghu, Robert J. Van Orden Jun 1988

Failure And Reconstruction Of A Waste Containment Pond Slope, Dorairaja Raghu, Robert J. Van Orden

International Conference on Case Histories in Geotechnical Engineering

A portion of a slope of a subsurface waste containment cell failed. It is believed that this failure could be attributed to a sudden drawdown condition caused by the pumping of treated wastewater effluent stored inside the cell prior to construction of the permanent liner. This conclusion seems to be in agreement with the results of a stability analysis conducted utilizing post-failure slope profile data. A discussion of the analysis of the failure and the reconstruction of the slope is presented in this paper.


Disposal Of Phenolic Waters From A Producer Gas Plant, Dorairaja Raghu, Hsin-Neng Hsieh Jun 1988

Disposal Of Phenolic Waters From A Producer Gas Plant, Dorairaja Raghu, Hsin-Neng Hsieh

International Conference on Case Histories in Geotechnical Engineering

Phenolic waters are generated in a producer gas plant in India. Since harmful environmental effects can result even with low concentrations of phenol in water, its disposal poses a problem. Four options for disposal were considered. One of these options considered involves disposal in a earthen pond situated close to a river. In order to avoid river pollution by possible seepage of phenolic waste, geotechnical aspects have to be considered. For each option, cost analysis is performed. This paper d1scusses as to how the final disposal technique is decided taking into account all the relevant aspects of the problem.


Evaluation Of Remedial In-Waste Leachate Head Reduction, Denise E. Mills, Donald A. Cordell Jun 1988

Evaluation Of Remedial In-Waste Leachate Head Reduction, Denise E. Mills, Donald A. Cordell

International Conference on Case Histories in Geotechnical Engineering

Water quality monitoring at Cedar Hil.ls Regional Landfill, in King County, Washington has indicated that shallow ground water perched in lodgement till has been impacted by solid waste disposal. A leachate mound to 50 feet in thickness was identified in the refuse which overlies the low permeability till. The leachate head over the till is sufficient to cause downward flow of leachate through the till to shallow ground water, and may contribute to water quality impacts at the site. Lowering the leachate head, therefore, may reduce the potential for impacts on water quality. A study was conducted to obtain estimates …


Geotechnical And Groundwater Site Characterization On The Umtra Project, J. A. Caldwell, R. A. Rager, L. Coons Jun 1988

Geotechnical And Groundwater Site Characterization On The Umtra Project, J. A. Caldwell, R. A. Rager, L. Coons

International Conference on Case Histories in Geotechnical Engineering

Reclamation of 24 inactive uranium mill tailngs piles involves remedial work to stabilize the piles for 1000 years. Site characterization of geotechnical and groundwater conditions at each site is undertaken prior to remedial action design. This paper describes the approach to UMTRA Project site characterization. A case history, Green River, is described. Details of site characterization costs for most sites are provided.
