Description: Miscellaneous Paper
Abstract: Eleven sites at the Naval Weapons Station, Concord, California, have been investigated for suitability for hazardous waste disposal. State and Federal regulations and technical guidance on siting and on disposal practice in general were used as the criteria for evaluating each site. Five sites were rejected as unsuitable based on surficial examinations. Bedrock exposed at two sites was regarded as unacceptable by virtue of the likelihood of adverse secondary permeability along rock joints. Potential for slope instability largely eliminated a third site, and high water table made two others unsatisfactory for meeting state requirements. Five remaining sites passed the early screening and required subsurface investigations for completion of the evaluation. Both field tests and laboratory tests were undertaken to determine the coefficient of permeability. The coefficient ranged from 10⁻³ to 10⁻⁸ cm/sec at the small scale of laboratory testing. Field-determined values mostly ranged more narrowly from 10⁻⁵ to 10⁻⁶ cm/sec in bracketing a variety of material types over vertical intervals of several feet. None of the eleven sites strictly satisfied State criteria for low permeability.
