A Five Year Water Research Plan For The State Of Arkansas, Robert E. Babcock

Technical Reports

The present economy and quality of life in Arkansas have largely been determined by our natural resources and the way they have been used. Likewise, insuring a sound economic future and a healthful environment in the state will depend on the efficiency and the wisdom with which nature's gifts are managed in the future. As the state's population grows and places new demands on finite resources, the need for effective resource management becomes increasingly critical. Often, a history of plenty can lead to the belated recognition of emerging resource problems. In Arkansas, such is the case with the state's water …

Water Quality Aspects Of Coal Transportation By Slurry Pipeline, James W. Moore

Technical Reports

The research program was designed to accomplish three major objectives. These were tot 1) identify and characterize the water quality changes that will occur as a result of the movement of western coal by slurry pipeline; 2) determine the feasibility of utilizing poor (impaired) quality water, such as municipal and industrial effluents, as the slurry medium, and: 3) determine the treatment measures applicable for restoring the slurry wastewater quality to acceptable levels, if required. The focus of the research program was generic rather than specific for any particular pipeline. Consequently, the emphasis was on establishing general ranges of data rather …

Federal Lands, Laws and Policies and the Development of Natural Resources: A Short Course (Summer Conference, July 28-August 1)

Even before the [Natural Resources Law] Center was established [in the fall of 1981], the [University of Colorado] School of Law was organizing annual natural resources law summer short courses. To date four programs have been presented:

- July 1980: "Federal Lands, Laws and Policies and the Development of Natural Resources"

- June 1981: "Water Resources Allocation: Laws and Emerging Issues"

- June 1982: "New Sources of Water for Energy Development and Growth: lnterbasin Transfers"

- June 1983: "Groundwater: Allocation, Development and Pollution"

Ute Self-Determination In Setting Tribal Resource Development Policy, Herbert H. Fullerton, Mac Mckee, Roger D. Hansen

Reports

The Ute Indian Tribe of northeastern Utah has large land holdings rich in water and energy resources. Revenues from these sources have created capital that can potentially be used by the Tribe to further develop its resources and expand its agricultural and business enterprises. Realities, however, complicate this simple scenario in that the Tribal goals are broader than pure economic gain and that increased incomes may mean sacrifices in terms of these other goals. The Tribe faces the problem of how best to develop its water resources in a way that best meets its multiplicity of needs.

Effects Of Changes In Surface Water Regime And/Or Land Use On The Vertical Distribution Of Water Available For Wetland Vegetation: Dynamic Model Of The Zone Of Aeration (Part 1 Of Completion Report For Project A-023-Ark), Robert N. Maccallum, R. A. Sims

Technical Reports

A mathematical model by Green, simulating one-dimensional vertical ground-water movement in unsaturated soils of the prairie region of Kansas, has been adapted for use in a wetlands environment typified by the wetlands forest of Eastern Arkansas. The model consists of two second-order, non-linear, partial differential equations and an algorithm for their numerical solution. The original model was extended to include functions for seasonal changes in transpiration and for drainage of excess precipitation. Before the addition of the two functions, the model reliability was limited to one growth season.

Effects Of Changes In Surface Water Regime And/Or Land Use On The Vertical Distribution Of Water Available For Wetland Vegetation: Portable Environmental Data Logger And Sensors (Part Ii Of Completion Report For Project A-023-Ark), Robert N. Maccallum, R. A. Sims

Technical Reports

An instrumentation and recording package and several transducers were constructed and used to collect data on the environmental parameters thought to affect wetland vegetation growth and reproduction. These parameters were temperature, humidity, wind velocity, depth of water table, and amount of surface water. The data were collected four times a day and recorded on a magnetic cassette tape that could record for as long as 90 days. The tapes were read and the data were converted to engineering units by a microcomputer-based instrument constructed for that purpose.

Ozonation At The Stander Water Reclamation Plant, Johannes Van Leeuwen, J. Prinsloo

Johannes van Leeuwen

The results achieved by ozonation at the Stander Water Reclamation Plant, Pretoria, are discussed. A packed column together with an injector mixing device gave ozone· utilization levels higher than 95 % at dosages of about 10 mg/ dm3. Redistribution plates in the packing proved necessary to prevent poor adsorption due to backmixing in the gas phase. Disinfection is satisfactory if total oxidant residuals can be maintained at more than 0,2 mg/dm3 for 15 min. The results indicated that ozonation also lowered the chemical oxygen demand and total organic carbon concentration in the water. In spite of the fact that it …

An Avoidance Response Bioassay For Aquatic Pollutants, Jeffrey A. Black, Wesley J. Birge

KWRRI Research Reports

Avoidance response bioassays were conducted with eight aquatic contaminants, including cadmium, copper, mercury, zinc, chloroform, dioctyl phthalate (DOP), trisodium nitrilotriacetic acid (NTA), and phenol. Tests were performed in a dual-channel fluviarium system, and the toxicant injection procedure used provided good regulation of exposure concentrations. Juvenile stages of largemouth bass (Micropterus salmoides), bluegill sunfish (Lepomis macrochirus), and rainbow trout (Salmo gairdneri), and tadpoles of the American toad (Bufo americanus) proved to be suitable animals for evaluating avoidance or attraction responses. The trout was the most sensitive species tested.

Avoidance was significant in tests …

Simultaneous Transport Of Water And 3hoh In Water, H. D. Scott

Technical Reports

Dispersion of ³HOH was studied at flow velocities less than 14 cm/day in a Captina silt loam using the half-cell technique. Two directions of transport were studied: movement of ³HOH in the same direction as water, and movement of ³HOH in the opposite direction to that of water. Results indicated that the dispersion coefficients were velocity dependent for equilibration times ranging to 21 hours. As the average pore flow velocity increased, the length of time needed for the dispersion coefficients to become independent of the flow velocity increased. When considering transport of ³HOH in the same …

Isolation And Enumeration Of Enteric Viruses From Primary Wastewater Sludge, Michael Wayne Nath

Biological Sciences Theses & Dissertations

The presence of large numbers of enteric viruses in wastewaters has resulted in concern regarding their significance and consequences for humans. Assessments of relative significance or consequences may most accurately be made following precise measurements of the range of virus types and amounts in wastewaters and sludges and after epidemiological considerations. In this study, results are presented pertaining to enteric virus isolation, concentration, and enumeration from primary wastewater sludges.

As an integral part of a comparison of isolation procedures, several anionic surfactants were examined for extraction of enteric viruses from primary wastewater sludges. Plaquing efficiencies for poliovirus type 2 and …
