Source Water Assessment Plan, Water Quality Division
Publications (WR)
The safe drinking water amendments of 1996 placed a strong emphasis on the goal to establish a nationwide effort to protect drinking water sources. As part of that goal, the legislation provided for a preliminary assessment of drinking water sources and an inventory of surrounding adjacent land use (ALUs). This nationwide effort will result in the first comprehensive look at the nation's drinking water sources from an assessment perspective. One of the outcomes of this nationwide assessment will be information that public water systems (PWSs) can use to help determine appropriate monitoring frequencies and to protect their sources of drinking …

Preliminary Ecological Risk Assessment To Assess The Implications Of Replacing Chromium Plating With Tantalum Coating, Erik Jonathan Weiss
Preliminary Ecological Risk Assessment To Assess The Implications Of Replacing Chromium Plating With Tantalum Coating, Erik Jonathan Weiss
Theses
An ecological risk assessment process requires a modeling tool that can adapt to changing environmental conditions. Computer simulation tools are a useful means to develop an ecological risk assessment, because if properly used they can provide an organized framework to evaluate multiple data sources, complex problems and hypotheses. An evaluation was completed of the University of Tennessee CHEMS-1 model that ranks and scores contaminant toxicity and exposure potential. Tantalum posed less of a hazard than hexavalent chromium to the terrestrial and aquatic animals. Although, results indicated that the vanadium compounds, in particular vanadium pentoxide, presented the greatest hazard, with hexavalent …

Water Quality In East Pond: Factors Contributing To Algal Blooms And Strategies For Remediation, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College
Colby College Watershed Study: East and North Ponds (2011, 1999, 1996, 1991)
Human activity within the watershed can greatly accelerate the eutrophication process by increasing the rate at which nutrients such as phosphorus and nitrogen enter the lake (Fernandez et al. 1992). Increased nutrient loading causes dramatic increases in algal populations resulting in algal blooms. Many New England lakes develop a greenish tint because of algal blooms during early summer or early fall (Smith, 1992). Populations of bacteria which feed on organic material rise because of increased food supply. Bacterial activity decreases the level of dissolved oxygen in the lake (Henderson-Seller and Markland, 1987). This process has occurred in East Pond and …
The Relative Importance Of Patch Area And Perimeter–Area Ratio To Grassland Breeding Birds, Christopher J. Helzer, Dennis E. Jelinski
The Relative Importance Of Patch Area And Perimeter–Area Ratio To Grassland Breeding Birds, Christopher J. Helzer, Dennis E. Jelinski
School of Natural Resources: Faculty Publications
Habitat fragmentation has been implicated as a major cause of population decline in grassland birds. We tested the hypothesis that a combination of area and shape determines the use of grassland patches by breeding birds. We compared both species richness and individual species presence in 45 wet meadow grasslands in the floodplain of the central Platte River, Nebraska. Bird data were collected through the use of belt transects and supplemented by walking and listening outside transects. Our data supported our primary hypothesis that perimeter–area ratio, which reflects both the area and shape of a patch, is the strongest predictor of …

Effect Of Human Disturbance On Small Mammal Communities In Itasca State Park, Minnesota, Nancy L. Staus, Kathleen Conforti, Leslie N. Clapper, Jennifer A. Longhenry, C. C. Schoenbauer, Michael S. Rentz, John R. Tester
Journal of the Minnesota Academy of Science
We determined effects of different levels of human disturbance on small mammal richness and relative abundance from live-trapping data obtained in Itasca State Park in northwestern Minnesota. We developed a quantitative measure of human disturbance based on disturbance units and trapped small mammals on three study sites, each reflecting a different level of disturbance. Our data revealed that small mammal diversity decreased with increasing human disturbance. Amount of ground cover and litter depth also appeared to be important in explaining differences in the demographic patterns of small mammals among sites.

The first scoping session, held …
The Effect Of Mechanical Noise And Natural Sound On Visitor Experiences In Units Of The National Park System, Dr. James Gramann, National Park Service, U.S. Department Of The Interior
The Effect Of Mechanical Noise And Natural Sound On Visitor Experiences In Units Of The National Park System, Dr. James Gramann, National Park Service, U.S. Department Of The Interior
All U.S. Government Documents (Utah Regional Depository)
This paper reviews research on the effects of mechanical noise and natural sound on visitor experiences in national parks. Three approaches to studying noise impacts are described. Most noise research to date has addressed the impact of air-tour overflights on visitor experiences. these impacts are localized with significant percentages of visitors in some parks reporting interference with natural sounds from aircraft noise. Research also shows that unthreatening natural environments can have significant stress-reducing effects for many people. However, it is unclear if these effects are due to hearing the sounds of nature or to a combination of hearing and seeing …

Water Resources Management Plan: Arches National Park & Canyonlands National Park, Utah, Lynn Cudlip, Kevin Berghoff, David Vana-Miller
All U.S. Government Documents (Utah Regional Depository)
The National Park Service recognizes the importance of preserving, conserving, and protecting water resources within its boundaries. Water resources, whether as large as the Colorado River or as small as a seep in Ernie's Country of Canyonlands National Park, play a distinctive role in linking ecosystems and , in general, provide habitat for a number of organisms. To protect park water resources, the Natinoal Park Service initiated a Water REsources Planning Program in 1991. The planning program provides an essential step in developing a comprehensive understanding of a park's hydrological system and the complex resource issues which surround it. The …

United States Army Corps of Engineers, Omaha District
Explosives contamination in surface or groundwater used for the irrigation of food crops and phytoremediation of explosives-contaminated soil or water using plant-assisted biodegradation have brought about concerns as to the fate of explosives in plants. Liquid scintillation counting, high-performance liquid chromatography, and gel permeation chromatography were utilized to characterize explosives (hexahydro-1,3,5-trinitro-1,3,5-triazine and trinitrotoluene) and their metabolites in plant tissues obtained from three separate studies. Analyzing tissues of yellow nutsedge (Cyperus esculentus), corn (Zea mays), lettuce (Lacuta sativa), tomato (Lyopersicum esculentum), radish (Raphanus sativus), and parrot feather (Myriophyllum aquaticum) …
