Download or read book Advances in Geosynthetic Clay Liner Technology written by Robert E. Mackey and published by ASTM International. This book was released on 2004 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soon after the inception of ASTM D35.04 Subcommittee on Geosynthetic Clay Liners, the first symposium on Testing and Acceptance Criteria for Geosynthetic Clay Liners (GCLs), STP 1308, was held on 29 January 1996, in Atlanta, Georgia. The intention of the symposium was to bring together the current knowledge and understanding regarding this relatively new product used in containment systems. Since that symposium, numerous GCL standards have been developed along with a greater appreciation of the product's capabilities and limitations. ASTM D35 determined it was time to assess the current state of GCL technology to better address possible revisions of the present ASTM GCL standards and determine what new standards will be required in the future.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-level radioactive waste (LLW) disposal facilities employ geosynthetic liner materials [e.g., high-density polyethylene (HDPE) geomembrane (GM) and geosynthetic clay liner (GCL)] in multilayer barrier systems to control the flux of contaminants into the environment. Long-term durability of geosynthetics in contact with LLW leachate is of particular importance because the design life of LLW barrier systems is commonly 1000 yr. This study focused on antioxidant depletion in 2-mm-thick HDPE GM immersed in synthetic radioactive leachate (RSL) with chemistry representative of leachate in LLW disposal facilities operated by the U.S. Department of Energy's environmental restoration programs. HDPE GMs were immersed in RSL at elevated temperature (25, 50, 70, and 90 °C), and antioxidant depletion rates were measured by oxidation induction time. Based on Arrhenius modeling, results demonstrate that antioxidant depletion time in 2-mm-thick HDPE GM is approximately 649 yr if correlated to an average field temperature of 15 °C. In separate experimentation, the radiation (e.g., alpha and beta) from LLW leachate had a negligible effect on antioxidant depletion in HDPE GM due to low dosage (2.3 Gy) over the 1000-yr service life and the surface effect of alpha and beta radiation on GM. This study also evaluated hydraulic conductivity of two conventional sodium-bentonite (CS and GS) and six polymer-bentonite (CPL, GPL, GPM, CPM, GPH, and BPC) GCLs permeated with RSL. In situ conditions were simulated with an elevated stress level to mimic a waste body mass and prehydration of GCLs from subgrade soil. For the CS, GS, CPL, GPL, and GPM GCLs, the hydraulic conductivity permeated with RSL gradually increased by a factor of 5-25 times, with final hydraulic conductivities ranging from 1.3 x 10-10 to 7.5 x 10-10 m/s at 20 kPa effective stress. In contrast, hydraulic conductivity of the CPM, GPH, and BPC GCLs were very low to RSL ([approx. equal to] 3 x 10-12 to 8 x 10-12 m/s) due to polymer hydrogel blocking. Increasing the confining stress from 20 kPa to 450 kPa reduced the hydraulic conductivity of CS GCL by approximately two orders of magnitude and eliminated preferential flow for CS GCL hydrated on a subgrade prior to permeation.

This book was released on 2007-09-22 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: President Carter's 1980 declaration of a state of emergency at Love Canal, New York, recognized that residents' health had been affected by nearby chemical waste sites. The Resource Conservation and Recovery Act, enacted in 1976, ushered in a new era of waste management disposal designed to protect the public from harm. It required that modern waste containment systems use "engineered" barriers designed to isolate hazardous and toxic wastes and prevent them from seeping into the environment. These containment systems are now employed at thousands of waste sites around the United States, and their effectiveness must be continually monitored. Assessment of the Performance of Engineered Waste Containment Barriers assesses the performance of waste containment barriers to date. Existing data suggest that waste containment systems with liners and covers, when constructed and maintained in accordance with current regulations, are performing well thus far. However, they have not been in existence long enough to assess long-term (postclosure) performance, which may extend for hundreds of years. The book makes recommendations on how to improve future assessments and increase confidence in predictions of barrier system performance which will be of interest to policy makers, environmental interest groups, industrial waste producers, and industrial waste management industry.

Download or read book Hydraulic Conductivity Testing of Geosynthetic Clay Liners (GCLs) Using the Constant Volume Method written by XD. Wang and published by . This book was released on 1999 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydraulic conductivity tests were conducted using open and constant-volume permeation systems on specimens from a geosynthetic clay liner (GCL). Two constant volume (CV) systems were employed: the falling-head constant-volume (FHCV) system and the constant-head constant-volume (CHCV) system. A conventional burette system using pressurized air was employed for the open system (OS) tests. The test results show that hydraulic conductivity tests can be conducted 30 or more times faster with the FHCV and CHCV systems than with an open system. Typically the permeation portion of the FHCV and CHCV tests can be conducted in one-half day. Slightly lower hydraulic conductivities are measured with the CV systems due to the slightly higher effective stress applied during testing with these systems. The CHCV system has several advantages over the FHCV system, including minimizing initial transient behavior, constant applied effective stress during testing, and simpler calculations.

Download or read book Geotechnical Practice for Waste Disposal written by D.E. Daniel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth scientists and geotechnical engineers are increasingly challenged to solve environmental problems related to waste disposal facilities and cleanup of contaminated sites. The effort has given rise to a new discipline of specialists in the field of environmental geotechnology. To be effective, environmental geotechnologists must not only be armed with the traditional knowledge of fields such as geology and civil engineering, but also be knowledgeable of principles of hydrogeology, chemistry, and biological processes. In addition, the environmental geotechnologist must be completely up to date on the often complex cadre of local and national regulations, must comprehend the often complex legal issues and sometimes mind-boggling financial impli cations of a project, and must be able to communicate effectively with a host of other technical specialists, regulatory officials, attorneys, local land owners, journalists, and others. The field of environmental geo technology will no doubt continue to offer unique challenges. The purpose of this book is to summarize the current state of practice in the field of environmental geotechnology. Part One covers broadly applicable principles such as hydrogeology, geochemistry, and con taminant transport in soil and rock. Part Two describes in detail the underlying principles for design and construction of new waste disposal facilities. Part Three covers techniques for site remediation. Finally, Part Four addresses the methodologies for monitoring. The topics of 'waste disposal' and 'site remediation' are extra ordinarily broad.
