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.

The purpose of the report is to evaluate environmental conditions and data at the site to determine whether a public health hazard exists as a result of exposure to contaminants in soils at the property. The City of Phoenix considers the site to be one of its highest priority brownfield projects due to its size, location, and threat to the public. Nearly the entire site is covered with solid waste including metal debris, tires, empty drums, construction debris, refuse, ceramics, empty alcoholic beverage bottles and cans, and human waste. A large pile of automobile fragments known as auto “fluff” is present on the southeast corner of the property. Contamination of soils at the site has occurred by disposal of auto fluff and transformer oils. The contaminants at the site include various metals and polychlorinated biphenyls (PCBs).

The purpose of this report is to document the evaluation of the public health effects of the air emissions from the Central Garden and Pet Supply Warehouse fire that was verbally provided during the response efforts to the fire event. The facility contained a variety of lawn and garden supplies including pesticides, herbicides, and pool maintenance chemicals. The fire also involved a portion of a pharmaceutical supply firm which contained medical supplies ranging from liquid and pill-form medicines to sterile syringes and other physical supplies.

The purpose of this health consultation is to evaluate the air monitoring conducted by the Arizona Department of Environmental Quality at Mary McLeod Bethune School (Phoenix, AZ) and evaluate the potential impact on public health. The air monitoring data includes particulate matter and metals. The ADEQ’s primary objective of this air sampling is to provide an understanding of the hazardous air pollutants in the Phoenix area.

The study reported here was designed to examine the impact of background meteorological conditions on the propagation of noise from urban freeways in the Phoenix area. The aim was to understand and predict how sound waves emanating from highways respond to the vertical profiles of atmospheric temperature gradients and velocity shear, so that sound measurements can be interpreted with regard to the environmental variability.

The purpose of this study was to conduct an evaluation of the Maryvale Weed and Seed Coalition. First, a process evaluation was conducted to examine the implementation of policies, goals, and planned activities by Maryvale Weed and Seed. Afterwards, an impact evaluation was conducted to assess the efficacy of Maryvale Weed and Seed in combating crime and disorder in the designated program area. The sections below outline both the characteristics of the affected site and the methodology used to conduct the process and impact evaluations.

The purpose of the present study was to conduct an evaluation of the Canyon Corridor Weed and Seed, using both qualitative and quantitative data to conduct process and impact evaluations. The process evaluation relied on official documents detailing site activities and interviews with key stakeholders. The impact evaluation relied on Uniform Crime Report (UCR) and call for service (CFS) data from the Phoenix Police Department (PPD) from 2002 through 2007, divided into two categories represented by a four-year “pre-test” and two-year “post-test”. The results of the process evaluation indicated that the Canyon Corridor Weed and Seed was actively engaged in activities pursuant of their original site goals, and adapting them as the site developed. The impact evaluation indicated that the crime rates in the Canyon Corridor Weed and Seed area experienced mixed declines and increases during the past two years of official programmatic activities when compared to the four years prior for crimes related to violent, property, drugs, and total crimes.

Prior to developing and approving new ordinances that would further regulate sex- offender distance restrictions and clustering, the Phoenix City Council approved a study to examine the nature and impact of sex-offender clustering. Their overall goal was to use the study to fill in some important knowledge gaps about the issue of sex-offender residential clustering in order to inform the development of effective policy. To examine this issue on behalf of the city council, we relied on a multi-methodological research design. We wanted to incorporate information from several different points of view, giving policy makers a more comprehensive perspective from which to inform their decision making. For this study, we relied on four resources: official police data, offender interview data, citizen survey data, and key stakeholder interview data.
