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.

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.

This study examines the feasibility of Turner Parkway and establishes guidance for the preservation of right-of-way to assure the functional integrity of the transportation framework. The Turner Parkway corridor is located 13 miles west of Loop 303 in northwestern Maricopa County. When completed, this parkway will be the first major, high-capacity, north-south facility west of White Tank Mountains.

One in a series of long-range transportation planning studies being conducted by the Maricopa County Department of Transportation to assess the ultimate corridor footprint requirements to enable consistent implementation across multiple jurisdictions. The study area for this project includes Peoria Avenue from the future Jackrabbit Trail Parkway alignment to Dysart Road (Peoria Avenue Corridor). The study area generally encompasses a two-mile wide corridor centered on the existing Peoria Avenue.

Arizona is one of the states in which the high-wage end of the employment distribution provides a more favorable impression of its job quality than that based on all employment. Thus, Arizona’s subpar job quality is not due to a scarcity of high-wage jobs, but instead results from lesser job quality in the remainder of the employment distribution. In particular, Arizona has an above-average share of very low-paying jobs that serve tourists and seasonal residents. In turn, the low overall average wage in Arizona — 7 percent less than the U.S. average — primarily results from factors other than job quality. The average wage in Arizona is less than the U.S. average in the vast majority of industries and occupations, both high- and low-paying.

Education decisions are among the most important choices people ever make. So we were surprised and disappointed to see an article so loosely reasoned and reckless in its conclusions as “Five Reasons to Skip College” published in Blank Slate at Forbes.com on April 18, 2006. The article never provides a numerical assessment of the costs and benefits of going to college, uses statistics inappropriately and in a way that biases the conclusions against college, contains conceptual errors on how to evaluate the return on a college education, and greatly exaggerates the only substantive criticism of typical evaluations of the financial worth of a college degree.

The purpose of the Verde Valley Multimodal Transportation Study is to develop a long-range regional transportation plan to guide the implementation of transportation improvements on the roads of regional significance in the Verde Valley, including I-17, State Routes, and roads on the County Regional Road System. This Study is an update of the 1999 Verde Valley Transportation Study Update.
