ADEQ has completed the following two reports for the Stone Avenue and Grant Road Water Quality Assurance Revolving Fund (WQARF) site located in Tucson, Arizona:

  • The Final Remedial Investigation (RI) Report.1 An RI is conducted to document the nature and extent of the contamination and the sources thereof; identify current and potential impacts to public health, welfare, and the environment; identify current and reasonably foreseeable uses of land and waters of the state; and obtain and evaluate any other information necessary for identification and comparison of alternative remedial actions. The final RI report includes the final remedial objectives report and responsiveness summaries regarding comments, issues and concerns raised during the community involvement process.
  • The Feasibility Study (FS) Work Plan to implement the FS.2 An FS is conducted to identify a reference remedy and alternative remedies that appear to be capable of achieving established remedial objectives and to evaluate them based on the comparison criteria to select a remedy.


The Stone Avenue and Grant Road WQARF site consists of two areas of soil contamination above Soil Remediation Levels (SRLs) surrounded by soil vapor contamination above US EPA Soil Vapor Regional Screening Levels (SVSLs) located in Tucson, Arizona. The extent of soil vapor contamination is bounded approximately to the north by West Jacinto Street, to the south by East Sahuaro Street, to the east by North Estrella Avenue and to the west by North Oracle Road. Contaminants of concern at the site are primarily Tetrachloroethene (PCE) but also trichloroethene (TCE) as a degradation product of PCE.
