Applying the Concept of Effective Data to Environmental Analyses for Contaminated Sites (PDF) (239K, 17pp, About PDF)

Analytical chemistry methods can be classified as 'definitive methods' or 'screening methods.' Environmental decision-makers frequently assume that definitive analytical methods generate 'definitive data,' while screening methods generate 'screening data.' This is misleading. Adopting the concept of 'effective data' could promote cost-savings while ensuring more reliable site decisions, because it recognizes that the information value of data depends on the interaction between sampling design, analytical design, and the intended use of the data.

The report provides information on innovative long-term monitoring technologies to detect contaminant releases beneath a liner containment system and identify potential problems with the integrity of final containment covers. Several of the technologies were specifically intended for vadose zone containment monitoring, while others were designed for leak detection or moisture measurements in other industries (petroleum, chemical, agricultural, geological exploration). The report summarizes available information on these technologies and provides examples of where the technology has been used. Information in the report can be used to provide some preliminary assessment on the applicability of these technologies.

Triad Issue Paper: Using Geophysical Tools to Develop the Conceptual Site Model (PDF) (908K, 15 pp, About PDF)

Order EPA 542-F-08-007

This technology bulletin explains how hazardous-waste site professionals can use geophysical tools to provide information about subsurface conditions to create a more representative conceptual site model (CSM). The CSM is a tool for gaining a synergistic understanding of the site, improve cost effectiveness, and improve decision-making within the Triad approach. Geophysical tools can be applied to create more robust CSMs with more complete data sets that result in a more representative and accurate depiction of the site characteristics at Brownfields and other hazardous waste sites.

Using the Triad Approach to Improve the Cost-effectiveness of Hazardous Waste Site Cleanups (PDF) (176K, 8 pp, About PDF)

Order EPA 542-R-01-016

U.S. EPA's Office of Solid Waste and Emergency Response is promoting more effective strategies for characterizing, monitoring, and cleaning up hazardous waste sites. In particular, a paradigm based on using an integrated triad of systematic planning, dynamic work plans, and real-time measurement technologies is encouraged. A central theme of the triad approach is a clear focus on overall decision quality as the overarching goal of project quality assurance, requiring careful identification and management of potential causes for errors in decision-making (i.e., sources of uncertainty).

Using the Triad Approach to Streamline Brownfields Site Assessment and Cleanup (PDF) (1.5MB, 48 pp, About PDF)

Order EPA 542-B-03-002

EPA's Brownfields Technology Support Center (BTSC) has prepared this document to provide an educational tool for site owners, project managers, and regulators to help streamline assessment and cleanup activities at brownfields sites. Strategies that reduce costs, decrease time frames, and positively affect regulatory and community acceptance also can improve the economics of redevelopment at brownfields sites. Increased attention to brownfields sites and the manner in which they are redeveloped places greater importance on the approach to site cleanup. This primer is one in a series that will address specific cleanup issues.
