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 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 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.

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.

This health consultation evaluates results of irrigation well samples collected by the Arizona Department of Environmental Quality in October 2003. Previous results obtained by the Blue Ridge Elementary School District in the summer of 2003 indicated trichloroethylene levels above the U.S. Environmental Protection Agency’s Maximum Contaminant Level. In addition, the most recent (2002) Annual Water Quality Report from the drinking water supplier, Arizona Water Company, was reviewed. A previous health consultation (Blue Ridge Elementary School, Lakeside, Navajo County, Arizona Health Consultation-April 30, 2003) reviewed environmental conditions at Blue Ridge Elementary School. Parents and school staff were concerned that environmental exposures were causing students to be absent from school. Drinking water quality reports, indoor air quality data, food safety, environmental sanitation records, student attendance rates, and the results of an annual parent satisfaction survey were evaluated in the consultation. Arizona Department of Health Services concluded that environmental conditions at Blue Ridge Elementary School posed no apparent public health hazard, and that attendance rates were similar to statewide attendance rates. As part of the 2003 health consultation, ADHS requested that the school district conduct water sampling from the on-site irrigation water wells for the school grounds. Those sampling results were not available when the 2003 health consultation was completed.
