ADEQ has completed the proposed remedial action plan (PRAP) for the Miracle Mile Water Quality Assurance Revolving Fund (WQARF) site in Tucson, Arizona. The PRAP documents the results of the remedial investigation/feasibility study (RI/FS) and identifies the proposed remedy and its estimated costs.

Information

The Miracle Mile WQARF site consists of areas of contaminated soil and plumes of contaminated groundwater located in Tucson. The site is bounded approximately by Curtis Road to the north, Prince Road to the south, Pomona Road to the east, and La Cholla Boulevard to the west. Contaminants of concern at the site are trichloroethene (TCE), chromium, and hexavalent chromium.

The proposed remedy for the site is as follows: soil vapor extraction at areas of high TCE concentrations in the soil gas and near the perched aquifer; maintenance of the cap and paved areas over hexavalent chromium contamination in soil; pump and treat and well-head treatment for the groundwater plume. The estimated cost to implement this remedy is approximately $21,358,000 for a period of 30 years.
