Superfund Site: VASQUEZ BOULEVARD AND I-70, DENVER, CO
Superfund Site Profile
The Vasquez Boulevard & Interstate 70 (VB/I-70) Superfund site is located in northeast Denver, Colorado. The site includes two commercial/industrial areas as well as residential properties in all or part of the following neighborhoods: Cole, Clayton, Swansea/Elyria, southwest Globeville and northern Curtis Park.
Historically, the area was a major smelting center for the Rocky Mountain West. Two smelting plants—Omaha & Grant and Argo—operated at the site for varying lengths of time, beginning as early as the 1870s, refining gold, silver, copper, lead and zinc. As a result, heavy metals were deposited in area soils at levels that, in some cases, posed a health risk to people living there. Groundwater was also impacted at the former smelter locations.
TOPICS IN FOCUS
Operable Unit 2 Removal Action: The City and County of Denver (CCOD) is planning construction of the Globeville Landing Outfall Project, which traverses the VB/I-70 Superfund site in the vicinity of the Denver Coliseum called Operable Unit 2. This work will require the excavation of potentially contaminated materials. Following EPA protocol, CCOD will conduct the work while ensuring that protective measures are taken to address any potential releases of, or worker exposure to, hazardous substances. EPA is overseeing CCOD’s work to ensure that there are stringent measures in place to protect human health and the environment and to minimize impacts to the community.
Work began at the site in January 2017 and is occurring largely at night to avoid area traffic congestion during the day. All contaminated soil and debris is being handled and disposed of safely and appropriately. Currently, CCOD contractors are excavating soils from the Globeville Landing Park, some of which is being stockpiled on site (clean top soil), while some is being transported off site to the Denver Arapahoe Disposal Site (DADS) in Aurora. CCOD contractors are also installing grout columns in the coliseum parking lot that will support the drainage structure. CCOD is conducting air and dust sampling at the site boundaries, and EPA is initiating air monitoring for PM2.5 and PM10 concurrent with excavation activities. EPA intends to operate the air monitors periodically throughout project construction as a part of our oversight activities.
