In fiscal year 2012, Osborn Elementary School District’s student achievement was slightly higher than peer districts’, and the District’s efficiency in noninstructional areas was mixed, with some costs higher and some costs lower than peer districts’. The District’s administrative cost per pupil was slightly lower than the peer districts’ average, and its food service program operated efficiently with a lower cost per meal, on average. However, the District’s transportation program operated less efficiently, and although the District made some improvements to the program in fiscal year 2013, better oversight is still needed. Further, the District’s plant operations costs were much higher than peer districts’, primarily because the District maintained a large amount of excess building space, even after closing a school at the end of fiscal year 2011. Lastly, the District needs to strengthen some of its computer controls.

In fiscal year 2012, Isaac Elementary School District’s student achievement was similar to peer district averages, and the District’s operational efficiencies were mixed, with much higher administrative and plant operations costs than peer districts’ averages but lower food service costs. Between fiscal years 2007 and 2012, the District decreased its classroom spending while it increased nonclassroom spending, primarily for administration and plant operations. At the end of fiscal year 2011, the District closed two schools to reduce costs, but its administrative and plant operations costs remained high, partly because of higher staffing levels. The District’s transportation program operated efficient bus routes but had much higher costs per mile and per rider than peer districts’, partly because it operated a smaller program but also because it offered more generous benefits. Finally, the District lacked adequate controls over user access to its computer network and systems.

In fiscal year 2012, Fowler Elementary School District’s student achievement was slightly higher than the peer districts’ averages, and the District operated efficiently. The District’s administrative cost per pupil was similar to the peer districts’ average, and it employed proper accounting and computer controls. The District’s plant operations costs per pupil and per square foot were lower than the peer districts’ averages primarily because of lower energy costs. Additionally, the District’s food service cost per meal was lower than the peer districts’ average, and the program was self-sufficient, in part, because the District paid the vendor that ran its program lower administrative and management fees than peer districts, on average. Further, the District’s transportation program was efficient, with lower costs per mile and per rider and efficient bus routes. However, the District did not accurately report its number of riders transported, which resulted in substantial overfunding for fiscal years 2011 through 2014.

The Arizona Department of Environmental Quality (ADEQ) requested the Arizona Department of Health Services to determine whether exposure to tetrachloroethylene (PCE) in the indoor air of a vacant dry cleaning facility and an attached convenience store posed a health threat to workers renovating the former dry cleaners and the patrons and employees of the convenience store. The former Viking Cleaners operated from 1954 until 2000. The building houses two businesses, Viking Cleaners, which is currently vacant but under renovation, and an attached convenience store that is currently in operation.

The purpose of this health consultation is to determine whether contaminants in groundwater from the Motorola 56th Street facility represent a threat to public health. The facility was first occupied in the spring of 1950 as the Western Military Electronics Center. From 1950 to 1958, it was primarily used for bench type electronics, electronic assembly, and semiconductor production. The chemicals used in these processes included solvent degreasers such as trichloroethylene, acetone, and freon, and metals such as cadmium, chromium, and arsenic. From 1959 through 1961, the facility was used primarily for document storage. Beginning in 1962, manufacturing of electronics resumed to include assembly of circuit boards, plating, and degreasing. Chemicals used between 1962 and 1974 included trichloroethylene, tetrachloroethylene, and a number of acids and metals including arsenic. In 1975, the facility began manufacturing liquid crystal products. These activities continued until 1982, when it was converted to office use. The investigations that have been conducted to date have shown that there are residual levels of arsenic and fluoride in down-gradient private wells west of the facility. Solvent contaminants that were found in the 1980s are no longer present at detectable levels in down-gradient private wells.

The purpose of the consultation is to identify any current groundwater use in the Motorola 52nd Street Superfund Site area that might result in human exposure to site contaminants. The Arizona Department of Health Services previously evaluated well use in Operable Units 1 and 2 in 1992. This report updates the well use inventory for Operable Units 1 and 2 and provides an evaluation of potential groundwater exposure pathways in Operable Unit 3.

This report presents the results of a study of vehicle occupancy conducted in Phoenix, Arizona to determine what factors have the greatest influence on having persons travel together to make trips in private vehicles. Although the data were collected in the Phoenix metropolitan area for the purpose of refining the MAGTPO mode split model for vehicle trips, the conclusions reached in this study of vehicle occupancy are also intended to be checked against data from other metropolitan areas.

The W.R. Grace facility in Phoenix, Arizona, received vermiculite concentrate from the Libby, Montana, vermiculite mine. W.R. Grace Company has owned and operated the Arizona site since 1964. In 1964 W.R. Grace purchased the company that had previously occupied the site and, following the relocation of its vermiculite exfoliation furnace from Glendale, Arizona, began processing vermiculite concentrate and marketing it under the Zonolite® brand. The objective of this health consultation is to evaluate exposure pathways and potential health effects in those persons who, between 1964 and 2002, may have been exposed to Libby asbestos as a result of vermiculite concentrate processing activities and waste materials from the W.R. Grace exfoliation facility in Phoenix.

The objective of this health assessment is to provide an evaluation of current and future potential health risks that may result from exposure to residual organochlorine pesticides at Franklin Elementary School in Phoenix, Arizona. The school has been unoccupied for the past 10 years. The historic school building is being restored by the school district, which plans to reopen the building for use as an elementary school. Several organochlorine pesticides were discovered in the soil during routine environmental sampling done in conjunction with the renovation. In particular, chlordane and dieldrin, banned in the United States in the early 1980's, were present in concentrations above screening levels.
