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.

In September 2005, some concerned Walker residents contacted the Arizona Department of Health Services in regards to the quality of groundwater in the area. The residents petitioned ADHS to perform well water tests to determine the character of the water, and whether there is any potential health risk associated with consuming or using the water. In response to the concerned community members and in agreement with the Agency for Toxic Substances and Disease Registry, ADHS collected water samples from the site and completed a health consultation. This health consultation evaluates if the levels of lead and other metals in the private wells in Walker area pose any adverse health effects.

This is the sixth annual assessment of influenza immunizations and pneumococcal vaccinations. This report analyzes Arizona Long Term Care System (ALTCS) Contractor performance.

Results of this study were based on measurements of a select group of members who were continuously enrolled from September 1, 2001, through April 30, 2002. The results did not include members who were not eligible to receive Medicare, those who received acute care services only, those who enrolled into ALTCS after December 1, 2001, or those who expired during the measurement period.

Results for the current measurement period are reported as relative changes from the previous measurement period, where applicable. The report also indicates whether this change is statistically significant, that is, whether the change is probably true and not merely due to chance.

This report includes Performance Indicators for services provided to children and adolescents enrolled with AHCCCS acute-care Contractors (health plans). The results reported here should be viewed as indicators of access to services, rather than absolute rates for how successfully AHCCCS and/or its Contractors provide care.

This report includes results for the measurement period from October 1, 2000, through September 30, 2001. Results of the indicators are reported in aggregate by urban (Maricopa and Pima counties) and the combined rural counties, as well as by individual Contractors. Results for the current measurement period are reported as a relative percentage change from the previous year. The report also indicates whether this change (increase or decrease) is statistically significant; that is, whether the change is probably true and not merely due to chance. The statistically significant value is calculated using the Pearson chi-square test.

This report analyzes Contractor Performance Indicators in three perinatal areas: 1) Low Birth Weight Deliveries; 2) Prenatal Care in the First Trimester; 3) Initiation of Prenatal Care. The results of this analysis should be viewed as indicators of access to services, rather than absolute rates for how well AHCCCS and/or its Contractors provide care.

This report includes results for the measurement period from October 1, 2000, through September 30, 2001. Results of the indicators are reported in aggregate by urban (Maricopa and Pima counties) and rural areas, and by individual Contractors that provide services to Medicaid recipients.

While virtually all children have contact with the health care system at some point, many problems may not be detected until children enter school. By offering low-income families and children access to health care and a regular point of contact, the AHCCCS program is uniquely positioned to provide high-quality, comprehensive preventive services that help assure the healthy development of children.

This report evaluates the potential exposure pathways associated with vermiculite concentrate processing activities at the Ari-Zonolite facility. The site is located in the near downtown area of Glendale, approximately ½ mile from the city hall, downtown shops, and other buildings. The former Ari-Zonolite facility received vermiculite from the Libby, Montana, mine. From 1951 to 1964, the site was leased the site to the Ari-Zonolite Company. Following the removal of the vermiculite concentrate processing equipment in 1964, several businesses have occupied the site. None of these businesses were involved in vermiculite processing activities. The last occupant of the former vermiculite processing building was an automotive restoration business, which vacated the site in 2002.

The officials of Sunnyside High School District and a United States Representative have expressed great concerns regarding the potential adverse health effects due to beryllium exposure in the vicinity of Brush Ceramic Products. The Arizona Department of Health Services was asked to determine whether beryllium released from Brush Ceramic’s plant poses a health threat to school children and employees, and residents in the vicinity of the facility.

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.
