View Resource The Stream Study

Based on material developed by the Save Our Streams program (Izaak Walton League of America), this educational resource on streams is provided by the University of Virginia at Charlotteville. The Stream Study homepage is an online guide for determining the water quality of streams, based on collecting and identifying stream-bottom macroinvertebrates (e.g., crayfish, mussels, and larvae of aquatic...
View Resource Use of Tracer Injections and Synoptic Sampling to Measure Metal Loading from Acid Mine Drainage

The US Geological Survey (USGS) has recently released this online information sheet about testing methods for acid mine drainage areas. An overview, discussion of stream discharge measurements in mountainous areas, tracer and synoptic sampling methods, conclusions and a bibliography are provided. The text, which comes from the USGS Water Resources Program, is accompanied by a few diagrams and...
View Resource Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory: Processing, taxonomy, and quality control of benthic macroinvertebrate samples

This US Geological Survey Open-File Report (00-212) describes analytical techniques for benthic macroinvertebrates. Available in .pdf format, the 49-page report includes information on such analytical techniques as chemical equipment supplies, taxonomic identification, and more.
View Resource WATERbase

The Great Lakes Water Institute at the University of Wisconsin-Milwaukee operates this large database of "water quality data for Lake Michigan and tributary rivers in the Milwaukee region." The facility conducts studies in this area to ascertain the impact of human activities and species introductions on this part of the lake's ecosystem. Data can be retrieved for seven different locations in...
View Resource The Color of Water

Provided by, the Why is Water Blue? (1) Web site starts off this Topic in Depth. Visitors will learn the factors that affect the colors we see, what color water actually is, and the basic physics and chemistry behind the phenomenon. This site is hard to beat for its clear explanations as well as its interesting photographs and illustrations. The second site, entitled the Common...
View Resource Methods for Measuring the Acute Toxicity of Effluents and Receiving Waters to Freshwater and Marine Organisms

The US Environmental Protection Agency has recently released a final regulation for Methods for Measuring the Acute Toxicity of Effluents and Receiving Waters to Freshwater. This involves the approval of several test procedures for measuring the toxicity of effluents and receiving waters, which are referred to as whole effluent toxicity or WET test methods. Visitors can download the entire 275...
View Resource A Water Quality Index for Ecology's Stream Monitoring Program

A Water Quality Index for Ecology's Stream Monitoring Program is a new publication being offered by the State of Washington's Department of Ecology. A description of the work in part states that "the Water Quality Index is intended as a tool to summarize and report Ecology's Freshwater Monitoring Unit's routine stream monitoring data...determined for temperature, pH, fecal coliform bacteria,...
View Resource Lake Water Monitoring and Analysis with Satellite Remote Sensing

From the Environmental Remote Sensing Center at the University of Wisconsin Madison comes the Lake Water Monitoring and Analysis with Satellite Remote Sensing Web site. Researchers and their cooperators have developed a method of assessing the water quality of Wisconsin's lakes from space using satellite imagery. Visitors to the site can read about how this is actually done, view an interactive...
View Resource Water Quality Standards Inventory Database

The Water Quality Standards Inventory is provided by the Information Center for the Environment, a cooperative effort of environmental scientists at the University of California, Davis. The GIS-based inventory of water quality standards consists of water quality objectives and beneficial uses established by each regional board for California surface waters. Users can browse by water quality...
View Resource USGS National Water-Quality Assessment Program

Since its inception in 1991, the USGS National Water-Quality Assessment (NAWQA) program has been collecting and analyzing data about more than 50 major river basins and aquifers across the United States. The core mission is "to develop long-term consistent and comparable information on streams, ground water, and aquatic ecosystems to support sound management and policy decisions." Visitors can...
