Water Organizations in a Changing West (Summer Conference, June 14-16)
Conference organizers, faculty and/or moderators included University of Colorado School of Law professors Lawrence J. MacDonnell, David H. Getches and James N. Corbridge, Jr.
Water organizations in the western United States range from small, traditional acequia associations to large metropolitan water suppliers. What do these vastly different kinds of organizations have in common? All are feeling the pressures of change in the region--growing urban populations, environmental concerns, and calls for public participation.
This year's summer program will examine how water organizations are adapting to these pressures for change. Speakers drawn from urban, agricultural, and community organizations will share their experiences …
Correlating Soil Test Phosphorus Losses In Runoff, D. H. Pote, T. C. Daniel, P. A. Moore Jr., D. J. Nichols, D. R. Edwards, A. N. Sharpley
Correlating Soil Test Phosphorus Losses In Runoff, D. H. Pote, T. C. Daniel, P. A. Moore Jr., D. J. Nichols, D. R. Edwards, A. N. Sharpley
Technical Reports
Phosphorus in agricultural runoff is often a major cause of accelerated eutrophication of lakes and streams. Previous research has indicated that the amount of dissolved P (DP) in runoff is directly related to P content of the surface soil. Decades of fertilizer application at rates exceeding those of crop uptake have elevated soil test P (STP) levels in areas of intensive crop and livestock production, making this the major source of DP loss in runoff. The objective of our experiment was to relate STP content of Captina silt loam to P concentration and loss in runoff, and determine which STP …

Water Quality And Fecal Indicator Bacteria, Mark S. Coyne

How can you tell if water is fit to drink? Color and taste aren't reliable guides for water safety. Clear water can be contaminated with chemicals or microorganisms the senses can't detect. One of the principle qualities of potable (drinkable) water is its freedom from microbial contaminants. This article will describe some criteria and methods that are used to determine the microbial quality of water.
The Fecal Coliform/Fecal Streptococci Ratio (Fc/Fs) And Water Quality In The Bluegrass Region Of Kentucky, Mark S. Coyne, J. M. Howell
The Fecal Coliform/Fecal Streptococci Ratio (Fc/Fs) And Water Quality In The Bluegrass Region Of Kentucky, Mark S. Coyne, J. M. Howell
Soil Science News and Views
In the mid 70' s, someone noticed that the ratio of two indicator bacteria in fecal wastes - fecal coliforms (FC) and fecal streptococci (FS) - was characteristic of particular animal wastes. In human wastes, the fecal coliform/fecal streptococci ratio (FC/FS ratio) was greater than 4. In domesticated animals, like cattle, the ratio was between 0.1 and 4.0. In wild animals, the ratio was less than 0.1. Since that time, many attempts have been made to use the ratio to determine the source of fecal bacteria in contaminated ground water.

Cover is an important component of aquatic habitat and fisheries management. Fisheries biologists often try to improve habitats through the addition of natural and artificial material to improve cover diversity and complexity. Habitat-improvement programs range from submerging used Christmas trees to more complex programs using sophisticated artificial habitat modules. Used automobile tires have been employed in the large scale construction of reefs and fish attractors in marine environments and to a lesser extent in freshwater and have been recognized as a durable, inexpensive and long-lasting material which benefits fishery communities.
Recent studies by the U.S. Bureau of Reclamation have quantified …

Data Sets
The Bay Study Group was created by the City of Tampa in 1976 to monitor the effects of pollution abatement that occurred in Hillsborough Bay when the city’s wastewater treatment plant was upgraded from primary to advanced treatment in 1979. The Bay Study Group documented a remarkable restoration of water quality parameters and biological indicators in Hillsborough Bay from the mid 1980s until 2009, when it was disbanded. This zip Geodatabase file contains the photo point locations, aerial photos, and flight maps for the year 1994.
