Tectonic, climatic, and land-use controls on groundwater recharge in an arid alluvial basin, Amargosa Desert
Unsaturated-zone profiles in alluvial sediments of the Amargosa Desert reveal distinct patterns of groundwater recharge corresponding to tectono-geomorphic setting and land-use history. Profiles of water potential, water content, and solute concentrations beneath irrigated fields, undisturbed native vegetation, and the normally dry channel of the Amargosa River reflect strongly contrasting recharg

The future of fire in California ecosystems
This chapter reviews the concepts developed in the book and challenges Californians to accept the fact that they live in fire-prone ecosystems. California’s variety of fire regimes are products of its wide diversity of vegetation, climate, topography, and ignitions. The role fire plays in an ecosystem is characterized by the fire regime attributes that describe the pattern of fire occurrence, beha

The mute swan, its status, behavior, and history in the U. K
For many years the mute swan has been considered a royal bird. It is a prominent resident throughout the United Kingdom (U.K.), often found on the inland waterways. Some people consider it to be a nonmigratory native bird because it doesn't tend to move large distances and doesn't often venture far from freshwater. A mute swan may often live out its life cycle in the same river valley in which i

Natural remediation potential of arsenic-contaminated ground water
Migration of leachate from a municipal landfill in Saco, Maine has resulted in arsenic concentrations in ground water as high as 647 μg/L. Laboratory experimental data indicate the primary source of arsenic to be reductive dissolution of arsenic-enriched iron oxyhydroxides in the aquifer by organic carbon in landfill leachate. A core from an uncontaminated part of the aquifer yielded no dissolved

Arsenic in ground water used for drinking water in the United States
The U.S. Environmental Protection Agency recently established a new maximum contaminant level of 10 micrograms per liter for arsenic in drinking water in the United States. Ground water is the primary source of drinking water for half the population of the United States. Several national assessments have found that high arsenic concentrations (above 10 micrograms per liter) are widespread in drink
