Critical tissue residue approach linking accumulated metals in aquatic insects to population and community-level effects Critical tissue residue approach linking accumulated metals in aquatic insects to population and community-level effects
Whole body Zn concentrations in individuals (n = 825) from three aquatic insect taxa (mayflies Rhithrogena spp. and Drunella spp. and the caddisfly Arctopsyche grandis) were used to predict effects on populations and communities (n = 149 samples). Both mayflies accumulated significantly more Zn than the caddisfly. The presence/absence of Drunella spp. most reliably distinguished sites...

Introduction to pathways of metal transfer from mineralized sources to biorecptors Introduction to pathways of metal transfer from mineralized sources to biorecptors
Since 1995, the Mineral Resources Program of the U.S. Geological Survey has funded a number of studies in the western United States that address environmental issues associated with mineral deposits.

Evaluation of the extent of contamination caused by historical mining in catchments of central Colorado Evaluation of the extent of contamination caused by historical mining in catchments of central Colorado
The U.S. Geological Survey conducted an assessment of stream water and sediment quality in central Colorado, an area of about 54,000 km2. The study area is focused on small tributary catchments in the Rocky Mountains. The Colorado Mineral belt, a northeast-trending mineralized zone that experienced base- and precious-metal mining at the beginning of the late 1800s and early 1900s, cuts...

Perchlorate data for streams and groundwater in selected areas of the United States, 2004 Perchlorate data for streams and groundwater in selected areas of the United States, 2004
This report presents data collected as part of a reconnaissance study to evaluate the occurrence of perchlorate in rivers and streams and in shallow aquifers in selected areas of the United States. Perchlorate, a component in rocket fuels, fireworks, and some explosives is soluble in water and persists in soils and water for long periods. It is biologically active at relatively low...

Reactive solute-transport simulation of pre-mining metal concentrations in mine-impacted catchments: Redwell Basin, Colorado, USA Reactive solute-transport simulation of pre-mining metal concentrations in mine-impacted catchments: Redwell Basin, Colorado, USA
With the increased importance of water resources in the western United States and many areas worldwide, the remediation of impacts from historical mining becomes ever more important. A possible process of making decisions about remediation for a catchment might include identification of principal sources of metals in the catchment, classification of the sources as natural or...
