The evaluation of environmental alterations by thermal loading and acid pollution in the cooling reservoir of a steam-electric station
(1970)
Thomas Hill Reservoir was built in 1966 by the Associated Electric Cooperative to provide cooling water for a team electric plant. The reservoir was formed by damming the middle fork of the Chariton River. It is located ...
Thickness of soil solum as a parameter of plant-available water storage capacity in soils underlain by carbonate rocks
(1970)
Available water storage capacities were determined by field measurement in limestone-derived soils with a range in depths to carbonate rock of 15 cm to more than 300 cm. Neutron probe access wells were installed and amounts ...
The impact of lead-zinc mining on the quality and ecology of surface waters in Southeast Missouri
(1970)
This study was initiated to determine the background concentrations of copper, lead, and zinc in the streams of the Viburnum Trend or New Lead Belt of southeast Missouri. Analytical methods were developed for atomic ...
Salt pollution of ground water
(1972)
An experimental model study was conducted to determine the behavior of induced motion in a salt water body overlain by fresh water. For the study, a narrow tank was constructed from plastic sheets of 0.25-inch thickness. ...
Information dissemination in the water resources field
(1976)
A study of mercury accumulation in trout taken from the trout parks and streams of southern Missouri is presented. Mercury in trout is determined by digestion in nitric acid, sulfurid acid, and potassium permanganate, ...
The detection and mapping of subterranean water bearing channels - phase 2
(1975)
"The research conducted under this Grant was directed towards the development of a method for the detection and delineation of subterranean cavities. Such cavities in the carbonaceous rocks of Missouri form a vast system ...
Influence of organic carbon and microorganisms on iron and sulfide concentrations in groundwater
(1977)
This study was undertaken to evaluate the feasibility of using a fluidized sand bed to coprecipitate the insoluble phosphorus complex of hydroxylapatite with calcium carbonate on the surface of sand grains to form dry ...
Water quality as related to possible heavy metal additions in surface and ground water in the Springfield and Joplin areas, Missouri
(1973)
Some 165 seasonal water samples were collected and analyzed for heavy metals from surface and subsurface sources in a one hundred mile area around Springfield and Joplin, Missouri, respectively. Joplin is in a former large ...
Optimization of operation of a system of flood control reservoirs
(1973)
Optimization of operation of a system of flood control reservoirs is established by the application of mathematical programming. The mathematical procedure is applied to two different types of systems, reservoirs in parallel ...
Sorption and desorption of chlorinated hydrocarbon pesticides in aquatic sediment minerals
(1971)
The fundamental sorption and desorption reactions between selected chlorinated hydrocarbon pesticides and clay minerals were established in this study. The effects of several important environmental factors, including pH, ...
Automated potentiometric techniques for the on-site monitoring of anion concentrations in water
(1970)
Characteristics of several of the new non-glass ion-selective electrodes and of several reference electrodes were studied in detail. The most significant finding of the research was the development of a new high accuracy ...
Potentiometric techniques for monitoring ions involved in water pollution
(1971)
The use of ion-selective electrodes, particularly the nitrate electrode, was explored for the analysis of ionic species in natural aquatic systems. Attempts to compensate quantitatively for the effects of interfering ions ...
Interfacial interaction of water and silicate minerals
(1974)
This program has relation to the categories of the nature of water and water cycle. In particular, the study deals with the basic interactions of water with the surface of minerals. The program has direct application to ...
Determination of the rate of tripoly and pyro-phosphate hydrolysis in sediments
(1974)
The rate of hydrolysis of tripolyphosphate (TPP) and pyrophosphate (PP) in sediments was determined. The sediments used were collected from Cape Fair, Thomas Hill Lake, Flat Branch Creek, and Maries River. The rate of ...
A water policy-land use computer simulation model
(1974)
This paper describes the philosophy, algorithms, and implementation of a computer-oriented land use forecasting-water policy simulation model. The model is applicable to SMSA's organized on a census tract basis by counties. ...
Pollution potential of aquatic sediments cancelled Corbeau A water policy-land use computer simulation model
(1974)
Existing water pollution problems did not occur suddenly, nor will this problem be solved overnight, even if there were no further pollutional discharges. This is because significant fractions of the past incoming pollutants ...
Prediction of water soluble arsenic in sewage-soil systems
(1975)
Missouri orchard soils were analyzed for total As, Pb, and Cu content. All Cu concentrations were normal, while Pb and As concentrations varied from natural levels to over 2000 ppm for Pb and 350 ppm for As. The Bray tests ...
Use of microwave remote sensors for determination of water in sub-soils
(1974)
The development of instruments for rapidly measuring the water content of subsoils is important in many areas of water resources research. For example, knowing the excess or lack of subsoil water can improve crops. The ...
Evaluation of single layered graded gravel as a protective filter on embankment slopes
(1970)
A laboratory study was conducted to evaluate the feasibility of using a random graded single layer of gravel as a protective filter against embankment erosion due to seepage. This evaluation was based on the observation ...
The preparation and oxidative properties of ferrate ion (FeO4^2-). Studies directed toward its use as a water purifying agent. Phase-1.
(1974)
The use of FeO4^2- in the treatment of deep-well and Missouri River water has been evaluated with respect to many variables. It is found that the addition of FeO4^2- effectively reduces the amounts of iron, manganese, ...
