The Arizona Department of Health Services reviewed existing data and performed a health consultation to evaluate the potentially adverse health effects due to VOCs created by air emissions from the Miller Road Treatment Facility. Prior to the existence of our current environmental regulations, local industries improperly disposed of organic solvents directly onto the ground or into dry wells. This subsequently contaminated all three levels of the aquifer.

This consult is in response to a petition request by the City of Tempe to de-list the area from the South Indian Bend Wash Superfund site, to allow the redevelopment into a multi-use retail marketplace. This consultation focuses on the potential for human exposures to the contaminants from soil vapors in the section known as the Landfill Area, or the McClintock/Rio Salado Brownfield Redevelopment Area.
