This document provides information that facilitates characterization of the site and selection of treatment technologies at metal-contaminated sites that are capable of meeting site-specific cleanup levels. The document does not facilitate the determination of cleanup levels. This document focuses mainly on the metalloid arsenic and the metals cadmium, chromium, lead, and mercury. Other metals are discussed, particularly those that have a strongly favorable or unfavorable influence on the performance of a treatment technology. Sections describing contaminants at metal-contaminated sites and the behavior, fate, and transport of metals in the environment are provided to assist the remedial manager in identifying the matrix and chemical species likely to be present. The section on remedial options outlines the arrangement of treatment trains to achieve performance levels. Technology performance data provided can help the remedial manager narrow options to those most likely to achieve site-specific cleanup goals. The descriptions of remedial options cover innovative and emerging technologies, as well as proven treatments.
