Nitrate Concentrations Of Ground Water Northern Madison County, Arkansas, Andrew Y. Austin, Kenneth F. Steele
Technical Reports
The presence of an extensive network of solution channels in the fractured carbonate bedrock and a thin permeable regolith in northwest Arkansas makes aquifers in this region susceptible to contamination. Because of these conditions, there is concern about nitrate contamination of the ground water from land applied animal wastes, commercial fertilizers, rural septic systems and municipal sewage systems. In response to these concerns a survey was conducted of the nitrate concentration in rural water wells in the carbonate aquifers of a 420 mi2 area of northern Madison county during "wet" and "dry" seasons in 1990. Information from well owners, drilling …
A Preliminiary Investigation To Determine The Economic Implications Of The "404" Permit For Constructing Agriculturally Related Reservoirs In Arkansas, Richard K. Ford, Charles R. Britton
A Preliminiary Investigation To Determine The Economic Implications Of The "404" Permit For Constructing Agriculturally Related Reservoirs In Arkansas, Richard K. Ford, Charles R. Britton
Technical Reports
A descriptive inquiry of the economic consequences of federal regulations which restrict the construction of agriculturally related reservoirs in Arkansas's wetlands is presented in this report. The applicable economic principles are identifyed and applied to the situation without the quantifiable information necessary to evaluate the alternatives. The difficulty of collecting the required quantifiable information necessitates the formulation of a different technique to unravel the dilemma. An alternative method for resolving the wetlands allocation question is presented for a public sector decision maker. This unconventional technique suggests that it may be desirable to estimate and compare the costs associated with the …
Virus Reduction By The Stanford Onsite Wastewater Treatment System, Mark A. Gross
Virus Reduction By The Stanford Onsite Wastewater Treatment System, Mark A. Gross
Technical Reports
A field study to examine the Stanford Onsite Wastewater Treatment System's ability to remove bacteriophage from wastewater was conducted. MS2 Coliphage was Injected Into the low pressure pipe (LPP) distribution system to achieve an Influent concentration of 1.6 x 106 plague forming units per milliliter (PFU/ml). The bacteriophage was Injected Into the system three times during the day, and samples were taken from drainage tiles of the treatment system. Tile drainage was assayed on conform bacteria host cultures for MS2 phage. The treatment system removed two to three logs (99% to 99.9%) of the phage. During the past two years, …

Dew Chemistry, G. H. Wagner
Technical Reports
From July, 1989 to July 1990 a total of 98 dews and 9 frosts were collected at the University of Arkansas Agricultural Experiment Station, Fayetteville. The total water flux from dews and frosts per year is less than 2% of that from rains. Acid and nutrient fluxes are also much lower in dew. In the following series of ions the number in parenthesis gives the % of the yearly flux of the ion in dew compared to rain for an average year: H+ (0.08), Ca2+ (23), Mg2+(9), K+(20), Na+(5), NH+(12), Cl-(7), S02/4-(5) and N0-/3 (6). A typical dew has a …
An Evaluation Of The Effect Of Discharging A High Quality Effluent Into A Small Ozark Mountain Stream, David G. Parker, Floyd E. Cotter, Sandra C. Parker
An Evaluation Of The Effect Of Discharging A High Quality Effluent Into A Small Ozark Mountain Stream, David G. Parker, Floyd E. Cotter, Sandra C. Parker
Technical Reports
Recently the newly constructed Fayetteville wastewater treatment plant went on line and directed a portion of its discharge to a point in the Mud Creek drainage basin that had previously not received any effluent. Prior to the discharge, a background study had been performed to establish the water quality in the basin. The background data, when compared to the data collected by this study, allowed any alteration of the stream water quality to be evaluated. Also the modeling procedure used to set the effluent limits for the treatment plant was analyzed. All stream data were compared to the limits set …
Fate Of Nitrogen From The Disposal Of Poultry Litter: A Simulation Approach, B. A. Ibrahim, H D. Scott
Fate Of Nitrogen From The Disposal Of Poultry Litter: A Simulation Approach, B. A. Ibrahim, H D. Scott
Technical Reports
A computer program was written to simulate the transport of nitrogen after an application of poultry litter to a pasture. The program was written in FORTRAN 77 to run on an IBM PC/AT or compatible personal computer or on a Sun SPARCSTATION. Simulation of water, solute and heat transport was by finite difference. Partition of rainfall into infiltration and runoff was by the SCS curve number method. A comparison was made of the computer model output with the results of a field experiment established at the Main Agricultural Experiment Station at Fayetteville. Poultry litter was applied at a rate of …
Optimal Reservoir Design Criteria In Conjuctive Use Of Surface Water And Groundwater For Soybean Irrigation In Eastern Arkansas, D. R. Edwards, J. A. Ferguson
Optimal Reservoir Design Criteria In Conjuctive Use Of Surface Water And Groundwater For Soybean Irrigation In Eastern Arkansas, D. R. Edwards, J. A. Ferguson
Technical Reports
A computer simulation model, named Arkansas Offstream Reservoir Analysis (ARORA) was developed to simulate present worth of net income from soybean production systems for conditions varying with respect to ground water availability, offstream reservoir capacity, and many other variables. Additional algorithms were incorporated into the model to enable it to optimize reservoir dimensions given realistic constraints and to identify the reservoir capacity corresponding to maximum present worth of simulated net income. The model was written in FORTRAN programming language and requires significant input data in order to provide significant flexibility with respect to the situations which may be accomodated. The …

Presentation Of Verified Algal Taxa As Reference Sources - Phase Ii, Richard L. Meyer
Technical Reports
The focus of this research project was to continue the development of a photographic system which would record living organisms using various forms of light microscopy with correct color and with arrested movement. These demands dictate the use of an electronic flash source with metering and control system located in a position following the passage of the light through the optical train. The system developed uses off-the-shelf components with a modified flashtube holder which positions the tube in the axis of the light beam between the field and iris diaphragm. The light is measured off-the-film so that light from the …

Nitrate Concentrations Of Ground Water From Limestone And Dolomitic Aquifers In The Northeastern Washington County Area, Arkansas, Kenneth F. Steele, William K. Mccalister
Nitrate Concentrations Of Ground Water From Limestone And Dolomitic Aquifers In The Northeastern Washington County Area, Arkansas, Kenneth F. Steele, William K. Mccalister
Technical Reports
The Ozark Region of Arkansas is a major poultry-producing area of the United States. Large quantities of poultry waste are spread as fertilizer on thin soils of pastureland overlying limestone and dolomitic aquifers. Because these aquifers provide domestic water supplies for the rural population and are susceptible to contamination from surface water, there is concern that nitrate leached from poultry litter is polluting the ground water. In response to this concern, well water from a major poultry-producing area was compared with that from a forested area in the northeastern Washington County area, Arkansas. Although nitrate concentration of the well water …
