Description:
Systematically conducted, well-documented treatability studies are an important component of the remedial investigation/feasibility study (RI/FS) process and the remedial design/remedial action (RD/RA) process under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). These studies provide valuable site-specific data necessary to aid in the selection and implementation of the remedy. This manual focuses on solvent extraction treatability studies conducted in support of remedy selection prior to developing the Record of Decision.
This manual presents a standard guide for designing and implementing a solvent extraction remedy selection treatability study. The manual describes and discusses the applicability and limitations of solvent extraction technologies, and defines the prescreening and field measurement data needed to determine if treatability testing is required. It also presents an overview of the process of conducting treatability tests and the applicability of tiered treatability testing for evaluating solvent extraction technologies. The specific goals for each tier of testing are defined and performance levels are presented, which should be met at the remedy screening and remedy selection levels before additional tests are conducted at the next tier. The elements of a treatability study work plan are also defined with detailed discussions on the design and execution of the remedy screening and remedy selection treatability studies.
The manual is not intended to serve as a substitute for communication with experts or regulators nor as the sole basis for the selection of solvent extraction as a particular remediation technology. Solvent extraction must be used in conjunction with other treatment technologies since it generates residuals. This manual is designed to be used in conjunction with the Guide for Conducting Treatability Studies Under CERCLA (Interim Final). The intended audience for this guide comprises Remedial Project Managers (RPMs), On-Scene Coordinators (OSCs), Potentially Responsible Parties (PRPs), consultants, contractors, and technology vendors.
