Options for Developing and Evaluating Mitigation Strategies for Indoor Air Impacts at CERCLA Sites. Air/Superfund National Technical Guidance Study Series, Report ASF-36

摘要

The purpose of the document is to present and analyze approaches that may be used to mitigate the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) site impacts on the indoor air quality of nearby structures. The document is designed to provide information that may assist in resolution of indoor air quality concerns at CERCLA sites. The procedures and methods, however, may also be useful in developing mitigation strategies for indoor air impacts from other hazardous wastes and hazardous materials sources. The document focuses primarily on mitigation methods that may be applied in the immediate vicinity of the impacted or potentially impacted structure(s). Reference is made to CERCLA site remediation methods that may also have a beneficial impact on indoor air quality, but these are not discussed in detail. The document includes summary level information on technical methods to prevent or reduce the intrusion of site related chemicals into the indoor environment and institutional methods to restrict the use of developed and undeveloped property to the extent necessary to reduce risks to acceptable levels.
