Brownfields properties are those sites where development has largely been encumbered by real or perceived environmental issues. A Brownfields investigation identifies impediments to Brownfields development and suggests solutions to facilitate redevelopment. Both government and community groups are concerned with the quality of Brownfields redevelopment and wish to ensure that the redevelopment will not only protect public health and environment, but also be economically viable and benefit the community. The Sustainable Brownfields Redevelopment process is a voluntary effort that actively engages property owners, developers, government agencies, and the community in conducting corrective action, economic evaluation, and other actions to promote the long-term productive reuse of a Brownfields property. The process can make great strides toward sustainable redevelopment since it encourages economic vitality of an area which in turn can reduce other social problems at Brownfields properties including poverty, unemployment, and crime. The Brownfields Law establishes that site characterizations or assessments conducted by entities with the use of Brownfields grants awarded under CERCLA must be conducted in accordance with the "all appropriate inquiry" standards established under the law. The Phase I ESA Practice complies with the "all appropriate inquiry" standards established under the Brownfields Law.
