Description

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.

Description

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,

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.

Description

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

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.

Description
Study of 23 pollen samples associated with archaeological sites in the Walhalla Glades district of Grand Canyon National Park yields surface sample data not consistant with prior research, possibly because the samples are actually of sediment deposited during the period the sites were occupied. Pollen record suggests local prehistoric cultivation

Study of 23 pollen samples associated with archaeological sites in the Walhalla Glades district of Grand Canyon National Park yields surface sample data not consistant with prior research, possibly because the samples are actually of sediment deposited during the period the sites were occupied. Pollen record suggests local prehistoric cultivation in a paleoenvironment quite distinct from that presently occurring in this district.

DescriptionClassroom excercise study of 32 samples from proxy surface, dune and pithouse contexts. Analysis used pollen categories rather than traditional pollen taxa. Results suggest the site's occupation history incorporates 5 distinct episodes of ecosystem change.

Description

Squash and possible maize pollen in sediment samples from checkdams suggests the features are prehistoric and were used for crop production. No evidence that local environment was different when the features were used.

Description
Unpublished report, 1965.

Study of pollen samples from these two Reeve Phase sites was undertaken excluding Cheno-am and Compositae pollen from the pollen sum. Cross-dating suggests a five-horizon pollen sequence; three horizons are evidenced a both sites, the other two are from samples superimosed on the occupation floors of rooms. Dates

Unpublished report, 1965.

Study of pollen samples from these two Reeve Phase sites was undertaken excluding Cheno-am and Compositae pollen from the pollen sum. Cross-dating suggests a five-horizon pollen sequence; three horizons are evidenced a both sites, the other two are from samples superimosed on the occupation floors of rooms. Dates between A.D. 1375 and 1490 are suggested for the sequence. Also discusses economically significant pollen types and presents cultural ecological interpretations. Published 1973
