The Strategic Plan comprises an ambitious set of goals and objectives. It is a “living” document that will guide our focus and activities. As such, some objectives and expected results will be subject to change as information and events unfold. Objectives and measures aligned to drive achievement have also been developed in Units, Sections, and Divisions throughout the Department.

From May 2005 to June 2005, the Arizona Department of Environmental Quality conducted a study, Potable Well Sampling Task 4.0, to determine if the chromium and chromium VI plume due to the discharge of the Pacific Gas and Electronic Topock Compressor Station has migrated under the Colorado River and impacted water supplies in Arizona. The ADEQ investigated the total chromium and hexavalent chromium (chromium VI) concentrations in (1) public water supply wells, (2) combined industrial and domestic water supply wells, and (3) private domestic water supply wells at Topock and Golden Shores, Arizona. The communities of Topock and Golden Shores have expressed their concerns regarding the findings. Thus, the ADEQ requested the Arizona Department of Health Services to evaluate the potential health effects of exposure to well water contaminated with chromium.

The Arizona Department of Health Services completed this health consultation at the request of the Arizona Department of Environmental Quality. This consult evaluates whether soil vapors from volatile organic compounds in the subsurface near the Silver Creek Subdivision in Tucson, Arizona are present at levels that may cause adverse health effects.

The Rodeo-Chediski Fire Complex began as a small blaze in a remote region of east-central Arizona and within days erupted into the largest wildfire in Arizona history. Fortunately, no lives were lost. However, from June 18, 2002 to the time of its containment on July 7, 2002, the Rodeo-Chediski fire destroyed over 490 structures and 467,000 acres of ponderosa pine and pinyon-juniper woodland—an estimated 500 million to 1.3 billion board feet of timber. Jurisdictions involved included the Fort Apache Indian Reservation, the Apache-Sitgreaves National Forest, the Tonto National Forest, and private lands adjacent to Highway 260, from the Town of Forest Lakes east to the City of Show Low. Virtually all of the acres burned were in Navajo County, with some damage in the contiguous counties of Coconino, Apache, and Gila Counties. This health assessment describes the fire events and summarizes the resulting public health impacts from the fire.

The Stoneridge subdivision is a growing rural community with approximately 5,000 residents. The Prescott Valley Water Company (Prescott Valley, AZ) provides drinking water for residents in this area. A resident in the community indicated that there is a “paint thinner” type odor coming from the tap water. The Prescott Valley Water Company sampled the water due to request of the resident. On July 27, 2004, the resident called the Arizona Department of Health Services to express his/her concern regarding the analytical results of benzene in tap water samples collected from faucets inside the house. As a result, the Arizona Department of Health Services completed a health consultation to evaluate if benzene and other volatile organic compounds in the water supplied by the Prescott Valley Water Company pose any adverse health effects.

The Arizona Department of Health Services conducted a carbon monoxide exposure survey among recreational boaters at the Maricopa County Lake Pleasant Regional Park during the 2003 Labor Day weekend. To investigate the extent that recreational boaters are exposed to carbon monoxide from a variety of watercraft, ADHS measured exhaled carbon monoxide to determine the amount of carboxyhemoglobin (COHb) present in their blood. To determine whether a widespread public health hazard exists because of carbon monoxide exposure from watercraft, the ADHS health consultation, "Investigation of Carbon Monoxide Exposure, Rotary Beach at the London Bridge, Lake Havasu, Arizona, May 25-26, 2003", recommended conducting further biomonitoring studies at other recreational lakes in Arizona. ADHS asked the Agency for Toxic Substances and Disease Registry (ATSDR), under its Cooperative Agreement Program with ADHS, to interpret data from the Lake Pleasant survey and to determine whether carbon monoxide exposure is a public health hazard among recreational boaters at Lake Pleasant.

The Arizona Department of Environmental Quality and the California Department of Toxic Substance Control worked together to assess background levels of naturally occurring metals in groundwater wells at Topock and Golden Shores, Arizona. The communities expressed concerns regarding the findings, thus the ADEQ requested the Arizona Department of Health Services to evaluate whether these naturally occurring metals in groundwater wells are present at levels that may cause adverse health effects.

The Santa Cruz County Health Department and the sheriff's office, along with the U.S. Border Patrol have expressed concerns regarding incidental contact with the water in Nogales Wash, Arizona. The public has expressed significant concern about direct public exposure to waters flowing in the wash. The Arizona Department of Health Services completed this health consultation to evaluate the levels of organic and inorganic chemicals at the request of the Santa Cruz County Health Department.

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.

The Arizona Department of Health Services reviewed existing data and performed a health consultation to evaluate the potentially adverse health effects due to VOCs created by air emissions from the Miller Road Treatment Facility. Prior to the existence of our current environmental regulations, local industries improperly disposed of organic solvents directly onto the ground or into dry wells. This subsequently contaminated all three levels of the aquifer.
