Strategic Property Analytic's expertise in property valuation has been pivotal in the resolution of globally renowned environmental contamination cases. Our extensive expertise encompasses property appraisal in cases involving potential contamination by a wide array of emerging contaminants, including but not limited to PFAS, 1,4 Dioxane, Perchlorates, TCE, DCE, PCE, Vinyl Chloride, VOCs, Gasoline, Fuel Oil, Odors, and various others. The following cases outlined below provide examples of the cases we have worked on. Please note that many of our projects are ongoing and confidentiality precludes us sharing further details.

Stringfellow Acid Pits

Jurupa Valley, California Determined the diminution in value on non-source properties. The U.S. government passed the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA), or the Superfund Act due to the three incidents, the Love Canal (NY), Times Beach (MI) and Stringfellow Acid Pit (or Sewergate-CA) because parties responsible to clean up the chemical waste dumps could generally not be located or were not able to pay for it. Stringfellow is one of the three most notorious superfund sites in U.S. history.
