Pavements represent one of the largest capital investments in Arizona’s aviation system. Timely airport pavement maintenance and rehabilitation are crucial because repairs are much more costly once the condition deteriorates below a certain level. Additionally, airport pavement weaknesses, such as cracks and loose debris, pose a significant safety risk to aircraft.

The Chandler Airpark area encompasses nine square miles surrounding the Chandler Municipal Airport. The area plan provides the City of Chandler with a document that will strategically guide future development in and around the existing airport. The two major goals of this plan are the protection of the Municipal Airport from residential encroachment and the aggressive economic development of the Airpark area.

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.

This Additional Site Characterization Work Plan presents a strategy for collecting site characterization information at the closed Maricopa County Cave Creek Landfill to support ongoing remedial action planning for trichloroethene-impacted groundwater underlying the site. The Work Plan supplements previous remedial investigation work plans prepared to characterize the nature and extent of site contamination.

To evaluate whether VOCs are migrating out of the landfills into the vadose zone, a soil vapor survey of the soil beneath the landfill bases was performed. Permanent vapor monitoring probes were installed and then sampled twice for VOCs. Groundwater beneath the landfills has been impactd by VOCs, namely TCE, DCE, and toluene.
