This special issue explores challenges and opportunities confronting higher education related to leadership at a variety of levels and the creation of linkages between students, faculty, administration, and community stakeholders necessary to address the many “wicked problems” facing society. One common thread among all the papers is that higher ed...

The integration of sustainability into higher education academic programs is occurring at an accelerated pace in response to international and national imperatives to rethink the way it serves the needs of society. Three case studies from the University of Nebraska-Lincoln, Northern Arizona University, and Kean University (NJ) outlines the academic...
Article
Pueblo Colorado Wash alluvial aquifer, located in northeastern Arizona on the Navajo Nation, is about 20 km long and 2-5 km wide and formed by infilling a canyon as deep as 70 m in Mesozoic and Tertiary sedimentary rocks. This aquifer is the main source of drinking water for many Navajo communities. The composition of shallow water (
Article
Masaya volcano in west-central Nicaragua has been emitting large amounts of SO2and HCl since 1979; discharges of HCl exceed 1400 metric tons (t) per day. A wedge-shaped region of west-central Nicaragua, downwind of the volcano, is consistently exposed to acidified rainfall containing washed-out HCl and H2SO4. The effects of this acid rain on the ec...

Full-text available
Acid rain (pH 2.5–5.0) from the volcanic plume of Masaya Caldera, Nicaragua, is composed of HCl and H2SO4 in systematically varying proportions. The dominance of HCl in volcanic acid rain makes it distinctly different from anthropogenic acid rain. The pH of volcanic acid rain is largely controlled by its HCl concentration. Volcanic acids are locall...
Article
The East Mancos River of Southwestern Colorado is a stream naturally acidified by sulfuric acid produced by outcrops in its stream bed. In the headwaters of the river, two 20m dipslope exposures of fault breccias in the Entrada Sandstone are mineralized by pyrite, chalcopyrite, sphalerite, and galena. Over a 13.4 km distance downstream, solution ch...
