This addendum to the 2005 work plan identifies how additional assessment of groundwater features and contamination at Cave Creek Landfill will be conducted.
This Additional Site Characterization Work Plan presents a strategy for collecting site characterization information at the closed Maricopa County Cave Creek Landfill to support ongoing remedial action planning for trichloroethene-impacted groundwater underlying the site. The Work Plan supplements previous remedial investigation work plans prepared to characterize the nature and extent of site contamination.
To evaluate whether VOCs are migrating out of the landfills into the vadose zone, a soil vapor survey of the soil beneath the landfill bases was performed. Permanent vapor monitoring probes were installed and then sampled twice for VOCs. Groundwater beneath the landfills has been impactd by VOCs, namely TCE, DCE, and toluene.
During the period of 1965 through 1984, Maricopa County operated a landfill leased from the U.S. Bureau of Land Management. In 1982 the County leased a separate parcel from the State for the development of a new landfill. The landfill stopped accepting waste in 1998.
