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 Transportation Needs Study is a planning effort undertaken cooperatively by Yuma County and the Multimodal Planning Division of the Arizona Department of Transportation. It has been funded and supported through the Planning Assistance for Rural Areas program of ADOT. The Study addresses the needs of multiple jurisdictions, as well as the needs of neighborhoods within these jurisdictions. It encompasses a mix of uses within developed and undeveloped zoning areas of the Mesa Del Sol and Foothills areas.

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.

This pamphlet describes CyberPort as multinational in its approach, considering the impacts of cross-border traffic at the local, state, and regional levels. The goal of CyberPort in Arizona is to increase the capacity of Nogales, San Luis and Douglas to serve as safe, secure and efficient gateways between the United States and Mexico. Nogales, as Arizona’s primary commercial port-of-entry, is naturally positioned to serve as the port of choice for western U.S.-Mexico trade.

The Nogales CyberPort Project began in the Spring of 2002 amid dramatic changes to the safety and security of U.S. borders. Throughout the following year, extraordinary change was experienced in policy and practice regarding the treatment of the border at the local, state and federal levels. While the movement toward a more efficient and effective border crossing environment has been underway in Arizona and the U.S. for a number of years, there is perhaps a no more appropriate time to undertake the effort to define and implement a CyberPort than right now.

Provides basic information about the source of surface water in Cienega Creek at the downstream end of the natural preserve, which will contribute to efforts to conceptualize and implement effective land management proposals for the SDCP. Study results indicate that the surface flow or subflow from Agua Verde Creek do not significantly influence the water in the Cienega Creek.
