Effects Of Treated Wastewater Effluent On Microbial Community Structure In A Natural Receiving Aquatic System, Matthew D. Hladilek

Masters Theses

Despite our dependency on treatment facilities to condition wastewater for eventual release to the environment, our knowledge regarding the effects of treated water on the local watershed is extremely limited. Responses of these lotic systems to the treated wastewater effluent have been traditionally investigated by examining the benthic macroinvertebrate assemblages and community structure; however, these studies do not address the microbial diversity of the water systems. In the present study, planktonic and benthic bacterial community structure were examined at fourteen sites (from 60 m upstream to 12,100 m downstream) and at two time points along an aquatic system receiving treated …

Effect Of Reservoir Function On Water Quality And Phytoplankton In Lake Taylorville, Christian County, Illinois, Scott Warren Phipps

Masters Theses

As is true for most reservoirs in agricultural areas, Lake Taylorville is currently impacted by excess sedimentation. A system of floodplain wetlands, holding ponds, and sediment basins is being constructed on the tributaries to the reservoir in effort to reduce sediment and nutrient loads. A comprehensive twelve-month assessment of water quality has been conducted to provide a baseline for evaluating the success of this restoration project and to allow predictions regarding future management strategies.

In reservoirs, a continuum of longitudinal gradients result in the establishment of three distinct zones possessing unique physical, chemical and biological properties. The function of these …

A Preliminary Study Using The Willow Cutting Method To Reduce Lake Shoreline Erosion, Jeffrey L. Bushur

Masters Theses

The Charleston Side-Channel Reservoir has been experiencing extensive shoreline erosion since its completion in 1982. A diagnostic/feasibility study of the reservoir in 1992 rated shoreline erosion as the second largest source of sedimentation. Sedimentation reduces the reservoir volume, increases nutrient loading, and increases water turbidity.

As a part of Clean Lakes Program Phase II, the use of willow cuttings for bank stabilization was proposed as a possible treatment for shoreline erosion. While the use of willows for streambank stabilization has been extensively reported, lake documentation is rare. This experiment determined the feasibility of such action for the Charleston Side-Channel Reservoir …

A Study Of Periphyton, Sediment And Diatom Community Structure As Monitors Of Heavy Metal Pollution In The Embarras River And Brushy Fork, David L. Vaultonburg

Masters Theses

The purpose of this study was to evaluate periphyton (diatom) and sediment heavy metal content and diatom community structure as potential monitors of heavy metal pollution in the upper reaches of the Embarras River system. The study was initiated due to recent industrialization in the area which could potentially contribute to the present heavy metal burden of Brushy Fork and the Embarras River. These streams are already subject to agricultural runoff, wastewater plant effluent, landfill leachate and other miscellaneous urban and highway runoff. The Embarras River system drains an area of approximately 2800 square miles in 11 east-central Illinois counties …

Effects Of Lake Management On Chemical, Physical, And Phycological Characteristics Of A Hypereutrophic Reservoir, Kaye J. Surratt

Masters Theses

Lake Charleston is a 1.1 billion gallon capacity side channel reservoir which was constructed in 1982 as a public drinking water supply for the City of Charleston in Coles County, Illinois. Past studies of the lake indicated an increase in eutrophication and the capacity to support large algal populations. Recent lake management practices include copper sulfate applications as an algicide and aeration to reduce flavor and odor.

In order to assess present lake status and to evaluate the effectiveness of lake management practices, two lake sites were sampled on a weekly basis from May to October, 1989. Chemical, physical, and …

Analysis Of The Charleston, Illinois Water Supply For The Presence Of Organic Mutagens Utilizing The Ames Salmonella/Microsome Assay, Steven Lee Washburn

Masters Theses

Water samples from the Charleston, Illinois water supply and selected agricultural run-off areas were tested for the presence of organic mutagenic chemicals. The Ames Salmonella/microsome mutagenicity assay utilizing strains TA98 and TA100 was used to analyze concentrated water samples. A special set of samples was exposed to the S9 activation system coupled with the TA98 strain to simulate the mammalian metabolic system.

No mutagens were detected in any of the samples tested. Several positive and negative control systems were included in the testing system. Negative control systems were used to determine the average spontaneous reversion rates for each strain for …

Raw Water Quality In The New Charleston, Illinois Pump Storage Reservoir, Kevin G. Lookis

Masters Theses

Charleston, Illinois, a city located in east-central Illinois, recently implemented a new concept in a raw water system. Due to storage capacity-sedimentation problems in the old Lake Charleston-Embarras River raw water supply, the Charleston Pump Storage Reservoir was constructed. The new system involved building a dike separating the Lake Charleston impoundment from the Embarras River. Water to increase the storage capacity of the reservoir can now be selectively pumped into the impoundment from the river.

Raw water quality in the reservoir was monitored on a weekly basis for a full year from August, 1981 to August, 1982. The levels of …

The Removal Of Viruses From Water By Conventional Water-Treatment Practices, Janet S. Ziegle

Masters Theses

The purpose of this investigation was to determine the effectiveness of conventional water-treatment methods in removing viruses from raw water sources. Those processes studied included alum flocculation, rapid sand filtration of fleeced and unflocced water samples, and chlorine disinfection.

This study was approached using coliphage f2 as a seeded indicator of treatment efficiency. Coliphage f2 was chosen as an indicator because of its similarities to enteric viral pathogens in both morphology and sensitivity to water-treatment processes. Coliphage f2 was found to occur naturally in surface waters, but not in numbers sufficient to interfere with calculations.

A sand filter for laboratory …

Water Quality And Benthos Of A Small East Central Illinois Stream, With A Selected Literature Review, Kenneth Lloyd Brummett

Masters Theses

Polecat Creek is an occasionally intermittent stream which drains approximately 18,368 acres in eastern Coles County, Illinois. It travels 15.2 miles through cropland and a partially wooded valley before it enters the Embarrass River 3 miles upstream from Lake Charleston. The stream ranges from 0.5 foot to 5 feet deep at a normal water level, with an average depth of 16 inches. It averages 12 feet wide, with a range from 4 to 20 feet.

A water quality study with 5 stations along the stream was conducted from January 1971 to July 1971. A qualitative benthos study at the same …
