PureGro | Hazardous Waste Site

Location: 

9801 W. Harrison Street, Tolleson, AZ 85353 

Discovery Date:

August 1997

Contaminants of Concern (COCs):

  • Groundwater and Soil Nitrate contamination due to fertilizers and pesticides handled in the past at this site

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: 

  • There is no offsite soil or groundwater plume at this time
  • An access agreement with Tolleson Union School District is underway to install two offsite monitoring wells on the school district's property.

Corrective Actions:

  • Operations at the site concluded in 1982. Tanks and equipment were removed.
  • Buildings demolished in 1993.
  • The 1994 Consent Order was amended January, 2003 to address soil and groundwater contamination issues, including ongoing investigations to determine the extent of soil and groundwater contamination from fertilizers and pesticides, after which a Corrective Action Plan (CAP) will be developed and implemented, as deemed necessary.
  • Reports submitted to date indicate extensive nitrate soil and groundwater contamination. PureGro is doing additional characterization to more accurately determine the nature and extent of on-site and off-site nitrate contamination. Thereafter, a corrective action plan will be developed and implemented.
  • ADEQ and PureGro are discussing amending the consent order to address ongoing investigations and corrective actions, as deemed necessary.
