Universal Propulsion Company | Hazardous Waste Site


Universal Propulsion Company 
25401 N Central Ave
Phoenix, AZ  85085

Discovery Date:

December 2003

Contaminants of Concern (COCs):

  • Perchlorate
  • Volatile organic compounds (VOCs)
  • TCE, 1,4-dioxane
  • Heavy metals (lead, arsenic)

Affected Media:

  • Soil
  • Groundwater

What are My Health Risks: 

For Soil | There is little to no health risk unless there is contact with skin or ingestion of contaminated soil.

For Groundwater | If you are connected to a public water system (PWS) there is little to no risk of impact from exceedances because the water is filtered through the PWS for residential and business use. | View Drinking Water Notices > 

If you have a private well in the vicinity of the exceedance, we encourage you to test the well water.

Site Summary: 

The facility designed and manufactured components for military aircraft. It consisted of several operational areas for manufacturing, assembling, testing and storing of energetic materials, and for the treatment of discarded wastes.  Groundwater sampling results show the presence of perchlorate and 1,1-dichloroethene (DCE). Contaminated soil was excavated and covers were installed at four locations to prevent future contaminant migration.  A network of onsite wells has been installed downgradient of the facility and, along with at least twelve private domestic wells in the vicinity, are sampled semiannually for perchlorate. Construction of a groundwater treatment system will be completed in September 2019.
