text: Acquisition, adaptive re-use, and disposal of a brownfield site requires advanced and specialized appraisal analysis techniques. For example, the highest and best use of the brownfield site may be affected by the contamination, both before and after remediation. Additionally, the value should take into account residual stigma and potential for third-party liability. Normal appraisal techniques frequently fail, and appraisers must rely on more advanced techniques, such as contingent valuation, case studies, or statistical analyses. A 2011 University of Delaware study has suggested a 17.5:1 return on dollars invested on brownfield redevelopment.
  A 2014 study of EPA brownfield cleanup grants from 2002 through 2008 found an average benefit value of almost $4 million per brownfield site (with a median of $2,117,982).
  To expedite the cleanup of brownfield sites in the US, some environmental firms have teamed up with insurance companies to underwrite the cleanup and provide a guaranteed cleanup cost to limit land developers' exposure to environmental remediation costs and pollution lawsuits. The environmental firm first performs an extensive investigation generally in the form of desk studies and potentially further intrusive investigation.
