Microbial And Chemical Affects On Leachate From Calcareous Soils Treated With Wastewater Effluent, Craig M. Paul

Theses and Dissertations

Increasing human populations are placing greater strain on water resources, prompting the use of treated wastewater effluent for irrigation in some areas, including the desert regions of the Western United States. To determine the potential effects of using secondary effluent for irrigation, we applied wastewater effluent and irrigation waters to natural and artificially constructed calcareous soils in greenhouse and field lysimeters, and in soil columns. The leachate from one field lysimeter contained increased fecal coliform counts than the effluent. Leachate coliform counts were decreased or not significantly changed in two field lysimeters. Electrical conductivity (EC), sodium adsorption ratio (SAR), chloride …

Availability Of Suitable Habitat For Northern River Otters In South Dakota, Alyssa M. Kiesow, Charles D. Dieter

Great Plains Research: A Journal of Natural and Social Sciences

Currently, the northern river otter (Lontra canadensis) is listed as a threatened species in South Dakota. We determined whether adequate habitat was available for reintroducing river otters in South Dakota. The 17 rivers/creeks included in the analysis were selected according to stream size, water gradient, and water permanence. A vegetation transect was conducted and a water sample was collected at each study site, ranging from one to four per river. Rivers/creeks were rated (1 = least suitable to 5 = most suitable) according to habitat requirements of river otters in the following categories: stream characteristics, watershed features, water …

The National Program structure of USDA-ARS provides an opportunity to coordinate research on problems of national and global significance. A team of USDA-ARS scientists is conducting nationally coordinated research to develop predictions of manure N availability to protect water quality and improve farm solvency. Experimental design and research protocols were developed and used in common across all participating locations. Laboratory incubations are conducted at each location with a minimum of three soils, three temperatures, two wetting/drying regimes, and two manure treatments. A soil from the central United States (Catlin silt loam, fine-silty, mixed, superactive, mesic Oxyaquic Argiudoll) is used as …

Nf05-631 Understanding Watersheds, Thomas G. Franti, Steven R. Tonn

University of Nebraska-Lincoln Extension: Historical Materials

Watersheds are dynamic and unique places. They are complex webs of natural resources, — soil, water, air, plants and animals. Together land and water make a watershed a whole system.

This NebFacts covers what a watershed is, how it works, its functions, how human activities can alter watershed functions, and its management.

A Review Of Phytoplankton Composition Within Chesapeake Bay And Its Tidal Estuaries, Harold G. Marshall, Lubomira Burchardt, Richard Lacouture

Biological Sciences Faculty Publications

Based on a continuous 20-year data base ofmonthly sampling in Chesapeake Bay and tidal regions of its major tributaries, 1454 phytoplankton taxa have been identified in these waters. They represent a diverse assemblage of species with a dominant diatom flora throughout the year, in addition to large seasonal representation by chlorophytes, cyanobacteria, cryptophytes and dinoflagellates. Included among this flora were 34 potential harmful or toxin producing species. The phytoplankton compositions associated with the seasonal successional patterns are discussed, in addition to characterizing the dominant floral relationships, with comparison to early composition records within the Bay. Several of the present day …

Nf05-632 Protecting Your Watershed, Thomas G. Franti, Steven R. Tonn

University of Nebraska-Lincoln Extension: Historical Materials

Everyone lives in a watershed. A watershed is the land area that contributes water to a location, usually a stream, pond, lake or river. Everything we do on the suface of our watershed impacts the water quality of our streams, wetlands, ponds, lakes and rivers. Like organs in a body, every part of the watershed is essential. What happens in one part affects other downstream parts. This NebFacts discusses the threat of pollutions in our watersheds, common runoff pollutants, and best management practices for protecting the watershed.
