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.

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.

The collaborative process for developing the Tusayan Community Wildfire Protection Plan began May 5, 2004 at a Tusayan/Grand Canyon Chamber of Commerce Board meeting in Tusayan. A CWPP is developed to assist local fire districts, local governmental agencies and residents in the identification of lands—including federal lands—at risk from severe wildfire threat and to identify strategies for reducing fuels on wildlands while improving forest health, supporting local economies, and improving firefighting response capabilities.

The wild land/urban interface is a concern in Coconino County because of the potential for wild land fuels to ignite combustible structures and vice-versa. Destroying homes, property, and trees is just one way that wildfire harms an area. Wildfires can destroy habitat, soils, and forest health, disrupting economic stability, transportation corridors, recreation opportunities, water supplies, and scenery, as well as undermining a community’s emotional and spiritual well-being. Reducing the threat of catastrophic wildfire is a priority in the wild land/urban interface. This plan outlines actions needed to prepare and equip the greater Flagstaff community to live and thrive within our fire-adapted ponderosa pine forests.

19 members of the Granite Mountain Interagency Hotshot Crew died after being entrapped and burned over on the Yarnell Hill Fire in Yarnell, Arizona. The purpose of this document is to provide:
* A timeline of events that occurred between the time of ignition on June 28 and the entrapment and burnover on June 30;
* An analysis of the fire behavior and fire weather on June 30;
* A discussion of overhead management, strategies and tactics used on the fire, and documentation of decision points leading up to the entrapment and burnover that claimed the lives of the firefighters.

A majority of the work performed by ADEQ's Nonpoint Source Program is funded by Clean Water Act grants, awarded by the U.S. Environmental Protection Agency which requires States to report annually on progress in meeting the schedule of milestones contained in their nonpoint source management plans, and report reductions in nonpoint source pollutant loadings and improvement in water quality resulting from program implementation.

Pima County's Cienega Creek Natural Preserve surface water and groundwater monitoring project. This report summaries PAG's groundwater and surface water monitoring between July and June each fiscal/ monitoring year. The report contains monitoring methodology, comprehensive maps, and graphs of trends for surface flow volume, wet-dry flow lengths, groundwater levels and water chemistry. It also contains information on drought, erosion and repeat photography.

Pima Association of Governments updated a portion of the Water Usage Along Selected Streams in Pima County, Arizona, which PAG created in 2000. The updated report and datasets show current potential water usage in these critical areas. Deliverables include the shapefiles, spreadsheets and maps that accompany this memorandum. The purpose of this report is to provide updated information about the location and pumping history of wells located in Pima County near shallow groundwater areas, generally located near drainages.
