Effect Of Drying On Cyromazine Loss From Surface-Applied Caged-Layer Manure, T. C. Daniel, D. H. Pote, D. R. Edwards

Arkansas Water Resources Center Technical Reports

In Arkansas, much of the environmental concern related to water quality has focused on the high volume of poultry fecal waste spread on the surf ace of local pastures to fertilize forage grass. Cyromazine (N-cyclopropyl-1,3,5-triazine-2,4,6- triamine), a feed-through larvicide used to control house flies (Musca domestica), is often a component of caged-layer manure. Cyromazine is quite soluble and stable in water, and previous research has shown that it can be readily washed from pasture plots by intense rainfall. Therefore, a study was conducted to evaluate increased drying time as a best management practice technique for reducing cyromazine runoff losses from …

Computer Simulation Model Calibration And Validation For Prediction Of Water Quality Impacts Of Poultry Waste Disposal, D. R. Edwards, T. C. Daniel

Arkansas Water Resources Center Technical Reports

Runoff and water quality data collected from two pairs of grazed fields in northwestern Arkansas were analyzed to support efforts to model runoff quality from areas receiving poultry manure and other fertilizer sources. The monitoring period described in this report was September 1, 1991 to April 30, 1993. One of each pair of fields was fertilized with inorganic fertilizer, and the other received either poultry litter or manure. Losses of fertilizer constituents were quite low from an agronomic standpoint, ranging from approximately 2-11 kg N/ha/year and 0.5-4.1 kg P04-P/ha/year. Annual losses of fertilizer constituents were dominated by only a small …

Fisheries Research Report No.100 - The Impact Of Trawling For Saucer Scallops And Western King Prawns On The Benthic Communities In Coastal Waters Off South-Western Australia, L. J.B. Laurenson, P. Unsworth, J. W. Penn, R. C.J. Lenanton

Fisheries Research Reports

A two year study was undertaken to collect data for the assessment of the impact of the saucer scallop and western king prawn trawl fisheries on the benthic communities in coastal waters off south western Australia, between 31°20'5 and 34°23'5 latitude.

Monitoring of reported commercial landings, on-board sampling of commercial catches, research vessel trawl surveys, experimental and exploratory trawling, and underwater television observations, have enabled the development of an extensive data-base on the fishery and benthic communities of the region.

These data indicate that the existing fishery operates on a number of relatively small, discrete grounds where saucer scallops or …

The Effects Of Composting Of Yard Wastes On The Ground-Water Quality: Wmu Farms Site, Kalamazoo, Michigan, Bryan Kirk Allen

Masters Theses

In the rush to find alternatives to landfilling of yard waste, federal and state agencies have identified composting as the main solution. There is therefore a need to address the possible environmental problems which could be associated with such composting operations. Compost may contain nutrients, organic acids, pesticides, and metals which could leach through soils to the ground water posing a potential contamination problem.

At the WMU Farms Site, two sites have been used for the composting of leaves by the City of Kalamazoo. The physical and chemical hydrogeology of these sites were characterized.

The results suggest that the presence …

Comparison Of Predicted And Observed Dioxin Levels In Fish: Implications For Risk Assessment, Judy S. Lakind, Daniel Q. Naiman

RISK: Health, Safety & Environment (1990-2002)

After comparing sampled and modelled dioxin levels in the tissue of fish near pulp and paper mill discharges, the authors argue that, until an improved bioaccumulation model is incorporated into EPA's Risk assessment process, determination of human health Risks associated with consuming dioxin-contaminated fish should be based on sampling.

Mixed Culture Biodegradation Of Pentachlorophenol, Hexachlorobenzene, And Tetrachloromethane Under Anaerobic Conditions, Jesse Zahn

Theses

Three chlorinated compounds, namely, Pentachlorophenol(PCP), Hexachlorobenzene (HCB), and Carbon tetrachloride were biodegraded under anaerobic conditions using a (CCl₄)mixed culture obtained from an anaerobic sewage sludge digestor in Linden, NJ.

Three sets of cultures capable of degrading each of the target compounds were established. Primary Enrichment Cultures (PECs) from the anaerobic sludge were exposed to each one of the target compounds. The cultures were able to degrade each target compound as follows: HCB, 0 to 1.2 ppm; PCP from 0 to 3-4 PPM; CCl₄, 0.5 to 15.5 PPM

One culture from each PEC group (CCl₄, …

Preliminary Public Health Assessment: Petrochem Recycling Corporation/Ekotek Salt Lake City, Salt Lake County, Utah, Agency For Toxic Substances And Disease Registry, Divisoin Of Health Assessment And Consultation

All U.S. Government Documents (Utah Regional Depository)

The Petrochem/EkoTek site was operated by several owners as a refinery from 1953 until 1978 and as a hazardous waste storage treatment facility and a petroleum recycling facility from 1978 through 1988. Removal of essentially all petroleum products and hazardous wastes in tanks and drums was accomplished from 1988 - 1991. The process that will lead to the complete clean-up of the facility is ongoing. The site was added to the National Priorities List (NPL) in October 1992. Exposure of humans to contaminants in soil and air is thought to have occurred near Petrochem. The source(s) of those contaminants in …

Geological Field Guide To The Cedar Point Biological Station, Keith County, Nebraska, Robert F. Diffendal Jr., Roger K. Pabian

School of Natural Resources: Faculty Publications

This field guide was produced by staff members of the Conservation and Survey Division of the University of Nebraska originally in 1979 at the request of Dr. Brent Nickol, former Director of the Cedar Point Biological Station. It is an introduction to the geologic history and paleoecology of the Cedar Point area intended for students, staff, and other persons using the camp. This revision has been made some 15 years after the first version to reflect changes in ideas resulting from new data collected during that time.

Users of this guide should take care when studying the rock exposures described …

Problem Analysis For The Vegetation Diversity Project, David A. Pyke, Michael M. Borman, U.S. Department Of The Interior, Bureau Of Land Management

All U.S. Government Documents (Utah Regional Depository)

Management of the majority of public rangeland in the Great Basin and Columbia-Snake River Plateau falls under the authority of the Bureau of Land Management. The flora of this land ranges from highly diverse native plant communities to deteriorated lands dominated by exotic annuals. Approximately nine percent of the BLM’s 78 million acres of public land in this region is degraded to such a degree that changes in land management alone will not result in significant improvement. The BLM intends to restore native plant communities on these deteriorated lands, but current revegetation techniques used to establish introduced perennial grasses are …

Application Of Organophilic Clay, Koshy Koshy

Theses

The overall goal of this project is to asses the feasibility of using clay to filter water contaminated with organic contaminants. The clays that were used were provided by the Union Carbide Corporation and the Industrial Mineral Ventures (IMV), a division of Floridin company. The organic contaminants that this project concentrated on were, naphthalene, 1,4-dioxane, and phenol. The feasibility studies were done by batch isotherm studies. The protocol for the batch studies were the same as the ones used previously for granular activated carbon. This project looked at a total of six Union Carbide clays and five IMV Floridin clays. …

Land Use Patterns In Relation To Lake Water Quality In The Salmon Lake Watershed, Problems In Environmental Science Course (Biology 493), Colby College, Colby College

Colby College Watershed Study: Salmon Lake and McGrath Pond (2009, 1993)

Salmon Lake has a history of algal blooms which have decreased the recreational and aesthetic value of the lake (Nichols et al. 1984). As early as the 1920’s, Salmon Lake was reported to have poor water quality. Algal blooms were reported throughout the 1970’s. Numerous complaints led to a study in 1975 by the Maine Department of Environmental Protection (MDEP) and another in 1984 by the U.S. Geological Survey to determine the cause of the accelerated algal growth in the ponds. Both studies concluded that the primary cause of these algal blooms was high concentrations of phosphorus in the water. …
