Spotlights on Technologies, Processes, and Initiatives

	Other Redevelopment Initiatives: Reducing Barriers to Redevelopment of Brownfields Sites In partnership with states, tribes, territories, and a broad range of stakeholders, EPA is undertaking the Land Revitalization Initiative to restore land to productive economic and green space uses.  [more]
	Superfund Redevelopment EPA's Superfund Redevelopment Initiative (SRI) reflects its commitment to consider reasonably anticipated future land uses when making remedy decisions at Superfund hazardous waste sites so that these sites can be cleaned up to be protective of human health and the environment under future uses.  [more]
	All Appropriate Inquiry: Standards and Practices to Provide CERCLA Liability Protections On January 11, 2002, President Bush signed the Small Business Liability Relief and Revitalization Act ("the Brownfields Law"). The Brownfields Law clarifies CERCLA liability provisions for landowners and potential property owners.  [more]
	USTs at Brownfields Sites: Technology Options for Tank Remediation Of the estimated 450,000 brownfields sites in the United States, approximately 100,000 to 200,000 contain abandoned USTs or are affected by leaks of petroleum from such tanks. EPA and many state and local leaders are committed to achieving sustainable development and preserving green space by cleaning up and reusing these petroleum brownfields, which are often located on corner lots and in other prime locations.  [more]
	Sustainable Management Approaches and Revitalization Tools - Electronic (SMARTe) Revitalization of contaminated sites is a global concern that requires an integrated approach to mitigate the risks to human health and the environment. Many countries have committed extensive resources to addressing environmental, social, and economic issues related to the cleanup and revitalization of brownfields sites.  [more]
	Keys to Technology Selection and Acceptance As described throughout the Road Map, innovative technologies and technology approaches offer many advantages in the cleanup of brownfields sites. Stakeholders in such sites, however, first must accept the technology.  [more]
	The Triad Approach: Streamlining Site Investigations and Cleanup Decisions The modernization of the collection, analysis, interpretation, and management of data to support decisions about hazardous waste sites rests on a three-pronged or "triad" approach. The introduction of new technologies in a dynamic framework allows project managers to meet clearly defined objectives.  [more]
	Data Quality and Representativeness: Keys to Cost-Effective Site Investigation The information value of data depends heavily upon the interaction among sampling and analytical designs in relation to the intended use of the data, the site-specific context surrounding that intended use, and the associated quality control. When this concept is understood, on-site analytical tools can play a major role in making environmental decision-making more efficient, defensible, and cost-effective.  [more]
	Supporting Tribal Revitalization Efforts State and tribal response programs oversee assessment and cleanup activities at most of the brownfields sites across the country. EPA provides technical assistance and other support to states and tribes in order to help them implement more effective approaches to attaining productive reuse of sites.  [more]
	Innovative Approaches to Assessment and Cleanup of Mining Sites The enactment of the Small Business Liability Relief and Brownfields Revitalization Act expanded the definition of brownfields to include mine-scarred lands (MSL), making these properties eligible for the benefits of the Brownfields Program.  [more]
	State Drycleaner Remediation Programs: An Innovative Approach to Cleanup State-mandated programs have had a major impact in turning former dry cleaner sites into marketable properties. Soil and groundwater contaminated by dry cleaning solvent are associated with many of these sites. Resource and budget constraints pose challenges to states as they undertake assessment and pursue remediation of these properties.  [more]
	Remediating Manufactured Gas Plant Sites: Emerging Remediation Technologies From the early 1800s through the mid-1900s, manufactured gas plant (MGP) sites were operated nationwide to produce gas from coal or oil for lighting, heating, and cooking. The gas manufacturing and purification processes conducted at the plants yielded gas plant residues that included tars, sludges, lampblack, light oils, spent oxide wastes, and other hydrocarbon products.  [more]
	Phytoremediation Technology: A Growing Field Phytoremediation includes the use of plants and natural processes to remediate or stabilize hazardous wastes in soil, sediments, surface water, or groundwater. By acting as filters or traps, plants can degrade organic pollutants, extract metal contaminants, or contain and stabilize the movement of contaminants.  [more]
	Cleanup of DNAPLs: A Widespread Challenge It is estimated that billions of dollars will be spent by the private and public sector to clean up sites contaminated with DNAPL. Denser than water, DNAPLs tend to sink through the water table and form a product pool on top of such impermeable soil layers as clay. DNAPLs also can sink and migrate laterally through fractures in bedrock.  [more]
	Vapor Intrusion: Subsurface Vapor Intrusion Guidance Vapor intrusion is the migration of volatile chemicals from the subsurface into overlying buildings. Vapor intrusion is typically associated with releases of volatile organic compounds (VOCs) such as petroleum products and chlorinated solvents to soil and groundwater from former gas stations, dry cleaners, automobile repair shops, and industrial facilities.  [more]
	Understanding the Role of Institutional Controls at Brownfields Sites: Major Concepts and Issues Institutional controls (ICs) are administrative and legal restrictions or limitations placed on the use of a site to minimize potential exposure to chemicals of concern or to prevent activities that might interfere with the effectiveness of a response action. Institutional controls are vital elements of response alternatives because they influence and supplement the physical component of the remedy to be implemented.  [more]
