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.
This document has been prepared to fulfill the requirements for a hydraulic study for the Cave Creek Landfill operated by Maricopa County.
A majority of the work performed by ADEQ's Nonpoint Source Program is funded by Clean Water Act grants, awarded by the U.S. Environmental Protection Agency which requires States to report annually on progress in meeting the schedule of milestones contained in their nonpoint source management plans, and report reductions in nonpoint source pollutant loadings and improvement in water quality resulting from program implementation.
This addendum to the 2005 work plan identifies how additional assessment of groundwater features and contamination at Cave Creek Landfill will be conducted.
This study involved the review of 417 ADEQ LUST site files and compilation of relevant data from 323 of these sites into an electronic database. It also involved the collection and analysis of over 700 supplemental groundwater samples, the assessment of aquifer flow properties from 32 wells at 11 sites, and more detailed characterization at six LUST sites representative of a range of conditions at AZ LUST facilities. In addition, over 300 groundwater level measurements were performed and 175 monitoring wells were re-surveyed in order to assess errors in standard practice and their impact on groundwater flow direction determination. An empirical analysis of groundwater impacts at AZ LUST sites was conducted using these data sets, with emphasis on identifying relationships between site conditions (e.g., geology, depth-to-groundwater, etc.) and groundwater impacts. Finally, a combined theoretical-spatial (GIS) analysis was performed to identify LUST scenarios posing the greatest threats to use of groundwater resources.
Universities provide numerous benefits to the community in which they are located. This report focuses on three of the financial/economic benefits. 1) Individual Financial Benefits of Higher Education; 2) Social Financial Benefits of Higher Education; 3) The Economic Benefits of University Research.
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.
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.
