Broadway-Pantano

Registry placement date: Sept. 15, 1998

Score: 48

County: Pima

Location: East-central Tucson, approximately bounded by Speedway Boulevard to the north, Calle Madero to the south, Pantano Wash to the east and Craycroft Road to the west

Contaminants of concern: Tetrachloroethene (PCE), trichloroethene (TCE) and dross (arsenic, cadmium and lead)

Action taken: A groundwater containment system was installed in 2003 to prevent westward migration of contaminated groundwater. The system was shut down in October 2012 because contaminant concentrations didn’t warrant continued operation, however, it is being maintained in case site conditions change.

The sources of groundwater contamination are the former Broadway North and South Landfills. A soil vapor extraction (SVE) system was installed at the Broadway North Landfill in 2000 to remove and treat volatile organic compounds (VOCs) landfill gases contributing to groundwater contamination. This system operated until 2002 and removed more than 5,000 pounds of VOCs. 

Status: The feasibility study (FS) was finalized in June 2017. The anticipated date for the proposed remedial action plan (PRAP) is June 2018.
