EPA and the U.S. Air Force have published a Remediation Technologies Screening Matrix and Reference Guide (Document No. EPA/542/B-93/005). The guide is intended to help federal site managers identify potentially applicable technologies for more detailed assessment and evaluation prior to remedy selection and summarizes the strengths and limitations of 48 innovative and conventional technologies for the remediation of soils, sediments, and sludges; ground water; and air emission/off-gases. The list of technologies includes in situ and ex situ biological, thermal, and physical/chemical processes. It includes treatment technologies and processes designed primarily for containment, waste separation, and enhanced recovery.
The document contains (1) a copy of the matrix evaluating the 48 technologies; (2) definitions for each of the technologies and processes evaluated; (3) definitions for each of the 13 factors (cost, performance, technical, developmental, and institutional) used to evaluate the technologies; (4) a technology-by-technology discussion of the contaminant groups treated, with supplemental information as needed to explain each rating on the matrix and factors that could limit the suitability and effectiveness of the technology; (5) a list of reference materials, including field demonstration reports and case studies; and (6) examples of contaminants included in each contaminant group in the matrix.
As part of its effort to improve awareness of the technical literature concerning innovative technologies, EPA has published the Literature Survey of Innovative Technologies for Hazardous Waste Site Remediation 1978-1991 (Document No. EPA/542/B-92/004). The bibliography was developed by searching commercial databases and software. Each citation contains the article or document title, journal or publication title, author, corporate source or publisher, conference name, and ordering information, where available. The citations are organized into survey reports; conference reports; in situ vitrification; soil washing; solvent extraction; thermal desorption; chemical dechlorination; soil vapor extraction; bioventing; biological slurry phase; biological solid phase; biological land treatment; in situ biological treatment; general biological treatment; and in situ ground water treatment. Although the search primarily focused on remediation of sites with contamination from hazardous waste, references for petroleum contaminated sites were also retained. The bibliography does not include waste streams or BDAT; fate and transport, unless explicitly related to treatment; oil spill cleanup other than underground storage tank sites; and above ground water treatment.
