Superfund Site Profile
EPA is in the process of updating this site profile page with additional current information. Until this update is complete, please click here for additional information about this site and to view site documents. Thank you for your patience.
The entire area of the Indian Bend Wash site (IBW site) covers about 13 square miles in Scottsdale and Tempe, Arizona. There are numerous industrial facilities located near the IBW site. Up until the 1970s, before current environmental regulations existed, industrial solvents containing volatile organic compounds (VOCs) were typically disposed of directly onto the ground or in dry wells. These disposal practices, along with other releases, resulted in the present soil and groundwater contamination at the site. EPA divided the site into two areas, known as North Indian Bend Wash (NIBW) and South Indian Bend Wash (SIBW). NIBW and SIBW are on separate cleanup tracks, as discussed below. Remedies have been selected and cleanup activities in various stages are currently underway.
