Chapter 1 describes the CQC/CQA process, identifies key responsibilities of individuals and organizations, and discusses the important components for proper CQC/CQA. Chapter 2 summarizes the construction process for waste containment units and discusses the importance of proper CQA. Information on the cost of CQC/CQA is also provided. Chapters 3-8 give detailed information on the CQC/CQA procedures (observations, tests, testing frequencies, corrective actions, and documentation) for compacted clay liners, geomembranes, geosynthetic clay liners, soil drainage materials, geosynthetic drainage materials, vertical cutoff walls, and other components such as pipes and appurtenances. The book is written as a technical guide for field technicians, field engineers, owners, regulators, and others interested in proper construction, CQC, and CQA of waste containment facilities.
