This document has been prepared to fulfill the requirements for a hydraulic study for the Cave Creek Landfill operated by Maricopa County.
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.
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.
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.
In March 2004, the U.S. Environmental Protection Agency requested information on efforts to monitor and protect children from exposure to lead in drinking water at schools. The Arizona Department of Health Services reviewed the state lead poisoning registry, and analyzed drinking water samples from 45 randomly selected schools. The Office of Environmental Health provided this consultation to help document our findings and supplement our response to the EPA. This work was also undertaken to help provide useful information should hazardous waste sites be discovered in the future near these schools. We also wanted to apply the ATSDR health assessment process in support of state and federal efforts to protect the health of children.
A landmark assessment of infrastructure needs in Arizona was produced by the L. William Seidman Research Institute in May 2008 for the Arizona Investment Council (AIC): "Infrastructure Needs and Funding Alternatives for Arizona: 2008-2032", that addressed infrastructure needs in four categories: energy, telecommunications, transportation, and water and wastewater. The information from the AIC report is a major input to the report that follows. Other types of infrastructure — most notably education, health care, and public safety — also are analyzed here to provide a more complete picture of infrastructure needs in Arizona. The goals of this report are to place Arizona’s infrastructure needs into national and historical contexts, to identify the changing conditions in infrastructure provision that make building Arizona’s infrastructure in the future a more problematic proposition than in the past, and to provide projections of the possible costs of providing infrastructure in Arizona over the next quarter century.
In this interview, Zah and Iverson discuss various political, economic, and controversial topics. Zah gives his impressions and thoughts about the Hopi government, including the struggle in trying to find the balance between traditional and progressive ideals. Zah also reflects on his positive relationship with Hopi chairman Ivan Sidney. The changes in Navajo politics, the Tribal Council, and chapter relationships are addressed, especially the 2010 vote for the reduction of the number of Council delegates from 88 to 24. Zah gives his overall assessment of the role of casino gaming in the Navajo economy. He goes into detail about the main issues that concerned and delayed the Navajo Nation in creating casinos. Zah lastly focuses on the Indian Civil Rights Act and the controversial confrontation that took place between Annie Wauneka and Ted Mitchell, which ultimately changed the ongoing leadership of DNA People’s Legal Services.
In this interview, Peterson Zah discusses various trust funds and how the settlement from a 1980’s court case against the Navajo Nation paved the way for greater growth and opportunity. Zah highlights key points in the taxation case, how the settlement money was used, and the issues that arose in trying to allot the funds in a fair way that appeased the whole Navajo community. Some of the trust funds that benefitted from the settlement were the Nation Building Fund, the Navajo Tribal Scholarship program, and the Land Acquisition Fund. Zah goes into detail about the permanent fund, briefly discusses methods of income, such as casinos, and creates a dialog about economic conditions on the reservation. Also brought up in the interview are the changing social conditions of the Navajo, especially as more people move off the reservation. The Navajo lifestyle is also changing, and Zah gives examples of these changes and explains what is creating the change.
