This document is not designed to be used as the sole basis for remedy selection. This guide and supporting information should be used only as a guidance document, and the exclusion or omission of a specific treatment technology does not necessarily mean that a technology is not applicable to a site.

It is important to recognize that the amount of information about technologies is rapidly growing. Information currently contained in this document was primarily excerpted from 1994 through 2000 source documents. This information was subsequently updated to the maximum extent possible through the interagency review process used in preparing this handbook. After identifying potentially applicable technologies, however, it is essential that prior to remedy selection RPMs consult the individual treatment technology vendor and/or government point of contact to evaluate technology, cost, and performance data in light of the most up-to-date information and site-specific conditions. Additional information to support identification and analysis of potentially applicable technologies can be obtained by consulting published references and contacting technology experts. The final selection of technology usually requires additional site-specific treatability studies. The reader is encouraged to keep information current by adding new information as it becomes available.
