Groundwater Remediation
Broadway-Pantano Groundwater Remediation
The Broadway-Pantano Remediation site includes the closed 130-acre Broadway North Landfill and groundwater contamination located west of the
landfill (Broadway-Pantano Remediation Site Map). Groundwater contamination was discovered in the late 1980's at this site. Since that
time, four City of Tucson production wells and one private well were shut down due to contamination from volatile organic compounds (VOCs).
The City has worked with private well owners in the affected area to ensure
their water supply is not impacted and to take action if it is. Four active private wells are sampled annually by Environmental Services Engineering & Technical Support, and the results reported directly to the well
owners. The City, working with St. Joseph s Hospital, implemented a cleanup system for the active hospital well, and continues to perform regulatory sampling there.
Environmental Services Engineering &
Technical Support, in cooperation with Pima County and Arizona Department of Environmental Quality (ADEQ), installed a deep soil-vapor extraction (SVE) system at the landfill in June 2000.
The system has been very successful at removing contaminants from the soil before they can reach the groundwater. ADEQ is now operating the SVE system and is currently evaluating the results to determine if the soil cleanup is complete.

Construction of the Western Groundwater Containment
Treatment Facility
The western groundwater containment system (WCS) is a pump-and-treat system to prevent the existing contaminant plume from traveling any further. It is a cooperative effort by ADEQ and the City of Tucson.
