Evaluation of acid-producing sulfidic materials in Virginia highway corridors

Road construction through sulfidic materials in Virginia has resulted in localized acid rock drainage (ARD) that threatens water quality, sedimentation, integrity of building materials, and vegetation management. Geologic formations associated with acid roadcuts were characterized by potential peroxide acidity (PPA), expressed as calcium carbonate equivalence (CCE), and total sulfur (total-S) in order to develop a statewide sulfide hazard rating map. The geologic formations were grouped into four categories based on potential acid-producing severity: i) Tabb formation (PPA<6 Mg CCE/1000 Mg; S<0.2%); ii) Ashe formation (PPA<18 Mg CCE/1000 Mg; S<2.0%); iii) Chesapeake Group, Lower Tertiary deposits, Millboro shale, Marcellus shale, and Needmore Formation (PPA<60 Mg CCE/1000 Mg; S<2.6%), and; iv) Chattanooga shale and Quantico slate (PPA<99 Mg CCE/1000 Mg; S<3.9%). Sulfide hazard analysis should be an essential step in the pre-design phase of highway construction and other earth-disturbing activities.

THE GREATER MIDDLE EAST AND REFORM IN THE BUSH ADMINISTRATION'S IDEOLOGICAL IMAGINATION

ABSTRACT. In pursuit of its foreign‐policy goals, the administration of President George W. Bush has attempted a dramatic reshaping of the vision of the Middle East in the American mind. References to the “new” or “greater” Middle East now include countries far outside traditional concepts of the region, including those in West Africa, Southeast Asia, and Central Asia. The administration argues that this region is defined not by cultural (Arab) or religious (Islam) characteristics but by a lack of democracy; hence a grand strategy is needed to execute reform. This article examines current U.S. efforts to achieve reform in the region, the components of the ideological construction of the New Middle East, the perceived role of Iraq, Turkey's potential role as a “model” for the region, and responses from the region to current U.S.‐led reform efforts.
