Nonaqueous Phase Liquids Compatibility with Materials Used in Well Construction, Sampling, and Remediation
The EPA Regional Ground Water Forum is a group of EPA professionals representing Regional Superfund and Resource Conservation and Recovery Act Offices (RCRA), committed to the identification and resolution of ground-water issues impacting the remediation of Superfund and RCRA sites. The Forum is supported by and advises the Superfund Technical Support Project. The compatibility of remediation, well construction, and sampling materials with nonaqueous phase liquids (NAPLs) is an issue that is a concern of Superfund decision-makers. This issue paper provides a comprehensive literature review regarding the compatibility of NAPLs with a wide variety of materials used at hazardous waste sites. A condensed reference table of compatibility data for 207 chemicals and 28 commonly used well construction and sampling equipment materials is provided. Field experiences illustrating incompatibility problems of common wastes are also included. This will assist monitoring and recovery system design personnel with the decision making process concerning the most effective materials to be used in heavily contaminated subsurface environments.
