Studies On Viruses In Water, Rex S. Spendlove, Bill B. Barnett, Dennis B. George, Dennis J. Adams, Stanley F. Hayes, Ronald B. Dean, David Ridinger, Darwin L. Sorensen

Reports

A new procedure for the detection of viral antigens in fecal material was developed. The test is performed by first diluting a fecal sample with phosphate buffered saline to give a liquid consistency. The pH is then adjusted to 8.5-9.0 and the solids are allowed to settle for five minutes. Supernatant fluid from above the fecal sediment is placed on the upper surface of a well of an inverted Immulon microtiter plate and incubated for one hour at 37 degrees C to allow virus to adsorb to the plastic. The Immulon plate is then washed three times with a Tween …

An Economic Evaluation Of The Salinity Impacts From Energy Development: The Case Of The Upper Colorado River Basin, Rangesan Narayanan, Sumol Padungchai, A. Bruce Bishop

Reports

To analyze the effect of potential energy development on water allocation and water quality in the Upper Colorado River Basin, a linear programming model is formulated. Using the model, changes in salinity are predicted. Further, least-cost strategies to maintain the established numeric salinity criteria through both structural and nonstructural alternatives are developed. The effectiveness of alternative control measures are examined within given institutional constraints. Based on cost-benefit analysis, optimal salinity levels over time are proposed. The economic feasibility of presently planned strucutral measures to reduce salinity is investigated and contrasted with nonstructural alternatives.

Integrating Water Resources And Land Use Planning, Jim Mulder, Kirk R. Kimball, Dean T. Larson, L. Douglas James, Lance R. Rovig, Dave Labau, Ken Sizemore

Reports

Information and recommendations were developed pertaining to the integrating of water resource and land use planning at a conceptual level. In the accomplishment of this goal, the report acts as a vehicle of information transfer to facilitate recognition of the interrelationships between land use and winter resources planning by practitioners in both areas. The approach that was used includes six basic components: 1) the clarification of current planning theory as it pertains to both water and land use planning, 2) analysis and review of historical and current land use planning practices, 3) review of historical and current land use planning …

Evaluation Of In-Line Direct Filtration For Virus Removal, Behjat Sadat Malek, Dennis B. George, Daniel S. Filip, Bill B. Barnett

Reports

The purposes of this study were to evaluate virus removal in treatment of water supplies by an in-line direct filtration pilot plant system and to suggest a system design to enhance virus removal. Isotherm and jar tests were conducted to evaluate the effects of pH, sodium ion concentration, and coagulants (alum and cationic polyelectrolytes Cat-Floc T, Nalco 8102, and 8103) on the bacteriophage MS2 contained in water. Isotherm studies were also conducted to assess the kinetic adsorption of MS2 to sand, anthracite, and garnet. Rapid sand, dual-media, and multi-media filters were tested in continuous in-line direct filtration operations. Approximately 95 …

Since nearly every water resource managment choice has two or more sides, differences must be resolved in decision making. Equitable resolution requires an understanding of the reasons for the differences. These reasons originate in the implemented plans have physical-environmental, economic, social, cultural, and political impacts at levels ranging from local to national or international in scope. Decisions are made by individuals and groups impacted in all of these dimensions and at all of these levels; the decisions generate additional impacts; and the entire interactive process changes water management practice in ways outside the control of any one decision point or …

Estimation Of Water Surface Elevation Probabilities And Associated Damages For The Great Salt Lake, L. Douglas James, David S. Bowles, W. Robert James, Ronald V. Canfield

Reports

Rising water surface elevations in perennial terminal lakes threaten major damages to shoreline industrial plants, transportation routs, and wetlands. Falling elevations increase pumping costs for industries extracting minerals from the lake water and reduce the quality of shoreline recreation. The managers of these properties need information on future lake level probabilities for planning, and public agencies need information on both probabilities and damages to determine whether lake level control is justified. Standard methods for estimating flood frequency and damages in riverine areas do not work well for terminal lakes because of the interdependency in annual peaks and the long advanced …

Introduction: Fibrex Corporation has capability for manufacturing various blends of cellulose fibers which have been used at locations throughout the country for temporarily controlling erosion on denuded land areas, and for serving as growth media for grass and other vegetation. Soil and climatic conditions vary greatly where these products are used, and it is not possible to determine by observation whether one is more effective than another in controlling erosion or promoting vegetative growth. Fibrex is desirous of knowing with some degree of confidence which products have the highest level of erosion control so that additional efforts can be directed …

Domestic Water Demand In Utah, Trevor C. Hughes, Robert Gross

Program Development Plan For An Operational Cloud Seeding Project In Utah With Evaluation Included, Geoffrey E. Hill

Reports

1. Operation Framework

In the arid climate of Southern and Central Utah, there is a continuing need to augment water supplies. While much of the water is needed for summertime use, particularly for irrigation, most of the available water is supplied by winter storms. Therefore, it is for the augmentation of the water stored naturally as snowpack at higher elevations that cloud seeding can make its greatest contribution.

Over the past several years, an attempt has been made to augment the snowpack by cloud seeding. Although there is a physical basis for expecting an increase in precipitation from a scientifically managed …

Modeling The Performance Of The Intermittent Sand Filter, P. A. Cowan, E. J. Middlebrooks

Reports

Several models were developed to predict the efficiency of the intermittent sand filter (ISF) in removing algae from wastewater stabilization pond effluent; volatile suspended solids (VSS) was the analytical technique used to identify algal concentrations. The first (ISF model) and second (modified ISF model) models consisted of two distinct portions: a surface algal layer (SAL) component and a sand phase component. In the ISF model, the sand phase component was described in terms of 20 empirical sand filter efficiency terms (20 ^ coefficients); in the modified ISF model, a functional relationship between ^ and filter depth was developed. The modified …

Erosion Control During Highway Construction: Volume 1, Calvin G. Clyde, C. Earl Israelsen, Paul E. Packer

Reports

Summary: Highway constuction as we know it today is a high-risk activity with respect to engendering soil erosion. In earlier days of road building, when rights-of-way were generally narrow and excavations mostly shollow, erosion was rarely a serious problem. Only occasionally was it considered necessary to design and apply specific measures for erosion control. With the advent of the superhighway involving far greater widths of right-of-way, and much deeper disturbance of the natural ground to affort the horizontal and vertical highway geometry necessary for high-speed travel, came a several fold increase in erosion potential and a direct need for specific …

A probabilistic river water quality model is developed with the capability of determinging the joint and marginal probability density function of biochemical oxygen demand (BOD) and dissolved oxygen (DO) at any point in a river. The one dimensional steady-state model can be applied to a river system with any reasonable number of point loads and diversions and lateral surface and subsurface inflow. The model can simultaneously consider randomness in the intital conditions, inputs, and coefficients of the water quality equations. Any empirical or known distribution can be used for the initial condition. The randomness in the water quality equation inputs …
