本文概述了作为《资源保护和回收法案》（RCRA）的一部分，针对南亚当斯县水和卫生区产生的废颗粒活性炭提出的除名申请中所准备的危险废物特性研究的结果。该研究分析评估了废GAC的许多特征，包括污染物成分浓度、毒性特征浸出程序（TCLP）测试、辐射参数和其他潜在危险废物特征。这项研究还从经验和理论上评估了如果GAC管理不当或六种最糟糕的情况之一，污染物释放到环境中的可能性- 发生了一起事故。最重要的是，该研究利用这些结果为预测污染浓度的增加提供了理论基础，而这对于废GAC通过TCLP测试并因此被归类为危险废物是必要的。

This paper outlines the results of a hazardous waste characterization study prepared as part of a Resource Conservation and Recovery Act (RCRA) Delisting Petition for spent granular activated carbon generated by the South Adams County Water and Sanitation District. The study analytically evaluated the spent GAC for numerous characteristics, including contaminant constituent concentrations, toxicity characteristic leaching procedure (TCLP) tests, radiological parameters, and other potential hazardous waste characteristics. The study also empirically and theoretically evaluated the potential for contaminants to be released to the environment if the GAC is improperly managed or if any one of six worst-case accident scenarios occurred. Most importantly, the study used the results to develop a theoretical basis for projecting the increased contamination concentrations that would be necessary for the spent GAC to fail the TCLP test and, thereby, be classified as a hazardous waste.
