Groundwater In The Inner Bluegrass Karst Region, Kentucky, John Thrailkill, Lawrence E. Spangler, William M. Hopper Jr., Michael R. Mccann, Joseph W. Troester, Douglas R. Gouzie
KWRRI Research Reports
The hydrogeology of about 12% of the 5600 km2 Inner Bluegrass Karst Region of central Kentucky was investigated by water tracing and other techniques. Using fluorescent dyes adsorbed on fabric and charcoal detectors, 96 traces (average length 2.7 km, maximum length 15 km) resulted in the identification of 38 groundwater basins (with areas up to 15 km2). Within the basins, subsurface flow is in a dendritic conduit system at depths up to 30 m below the surface, while in the interbasin areas which separate them flow is generally less than 5 m deep. Each groundwater basin discharges …

Atrazine Degradation, Sorption And Bioconcentration In Water Systems, Duane C. Wolf, Ramon L. Jackson
Technical Reports
The herbicide atrazine is used extensively to control broadleaf and grass weeds in such crops as sorghum and corn. A small portion of the atrazine may be lost from the area of application by surface runoff and could enter a stream or lake. The objective of this study was to evaluate atrazine degradation, sorption, and bioconcentration in watersediment systems. The results indicated that sediments with lower pH values and higher organic matter levels adsorbed higher levels of atrazine than sediments with neutral pH values and lower organic matter levels. Microbial decomposition of the herbicide was slow under the conditions of …

Management Practice Evaluation For Urban Areas In The Hampton Roads Vicinity: A Report To Hampton Roads Water Quality Agency, Gary F. Anderson, Bruce J. Neilson, Donald H. Campbell
Reports
Data was collected by the Virginia Institute of Marine Science from study sites in the designated Hampton Roads 208 area, and information from other studies published in the literature were used to examine the change in pollutant loadings brought about by the presence of management practices in urban test watersheds. The focus was on nutrients, BOD, and suspended solids.

Flood Insurance Study, Federal Emergency Management Agency
All U.S. Government Documents (Utah Regional Depository)
This Flood Insurance Study investigates the existence and severity of flood hazards in the City of Ogden, Weber County, Utah, and aids in the administration of the National Flood Insurance Act of 1968 and the Flood Disaster Protection Act of 1973. This study will be used to convert Ogden to the regular program of flood insurance by the Federal Emergency Management Agency. Local regional planners will use this study in their efforts to promote sound flood plain management. IN some states or communities, flood plain management criteria or regulations may exist that are more restrictive or comprehensive than those on …

Some Variations In Distribution Of Fishes In Large Mainstream Reservoirs Associated With Artificial Cover, Donald W. Johnson, Elizabeth M. Choinski
Some Variations In Distribution Of Fishes In Large Mainstream Reservoirs Associated With Artificial Cover, Donald W. Johnson, Elizabeth M. Choinski
KWRRI Research Reports
The influence of artificial cover (brush piles) on fish populations in Kentucky Lake and Lake Barkley was studied. Mature and larval fishes were collected from deep and shallow sites with and without cover in a bay of each lake. Highest densities of mature crappie, bass, and sauger were found adjacent to deep attractors, while larval crappie and minnows were most concentrated at shallow brush piles. Shad (both adult and larvae) were not congregated at attractor sites. Information gathered supports the continuation of artificial cover installation and water level management procedures which will provide high and stable levels through spring spawning …
An Ecological Analysis Of Relic Diatoms In Sediments Of Las Vegas Bay, Lake Mead, David Ross Hetzel
An Ecological Analysis Of Relic Diatoms In Sediments Of Las Vegas Bay, Lake Mead, David Ross Hetzel
Publications (WR)
Relic diatoms in sediments of the inner Las Vegas Bay, near the Las Vegas Wash sewage inflow, were examined in order to assess historic trophic conditions in this area of Lake Mead. Diatom sedimentation rates and ratios of Araphidineae/Centrales (A/C) diatom groups were determined from sediment cores collected in the old wash channel 1.5 km from the sewage inflow (station 2), in a small cove 1.5 km further downstream (station 3) and in an adjacent embayment off Gypsum Wash (station 4). Diatom sedimentation rates generally increased from the bottom to the top of each core, but pronounced minima existed at …
Impact Of Urban Stormwater Runoff On The Water Quality Of The Subsurface Lost River, Bowling Green, Kentucky, Donald Rice
Impact Of Urban Stormwater Runoff On The Water Quality Of The Subsurface Lost River, Bowling Green, Kentucky, Donald Rice
Masters Theses & Specialist Projects
Bowling Green, Kentucky is located in a distinctive karst region, characterized by subsurface drainage. The Lost River is a large subsurface stream which flows beneath the city. It receives much of the stormwater runoff from Bowling Green, since most of the city's runoff is directed underground. Significant pollutants in Bowling Green's stormwater runoff were identified from water quality test results of storm event grab samples, and a composite sample, of runoff entering the urban By-Pass Cave. Water quality test results were also obtained from storm event grab samples, and a composite sample, of the Lost River at the Blue Hole …
Analysis Of Organic N-Chloramines In Chlorinated Drinking Water, John Po Wen Yang
Analysis Of Organic N-Chloramines In Chlorinated Drinking Water, John Po Wen Yang
Chemistry & Biochemistry Theses & Dissertations
This thesis describes the development of a sensitive method for the separation and quantitation of organic N-chloramines in chlorinated tap water. 5-Dimethylaminonaphthalene- l-sulfinic acid has been synthesized and characterized. It yields highly fluorescent dansyl derivatives on reaction with N-chloramines. Conditions of the derivatization were optimized for the detection of N-chloropiperidine at concentrations in aqueous solution of 10-7 M. The technique gives a quantity of derivative which is proportional to the concentration of chloramine present over the range examined (10-7 M to 10-4 M). High pressure liquid chromatographic separation of dansyl derivatives of amines and amino acids has …
The Effects Of Kepone On The Estuarine Copepod Acartia Tonsa, Judith Marie Wilson
The Effects Of Kepone On The Estuarine Copepod Acartia Tonsa, Judith Marie Wilson
Biological Sciences Theses & Dissertations
Due to the contamination of a 113 km reach of the James River, Kepone poses a serious environmental threat to the Chesapeake Bay. The purpose of the study is to determine the acutely toxic and sublethal levels of kepone for the copepod Acartia tonsa, and to investigate what effects those levels may have on filtration rates.
Kepone was determined to be acutely toxic to A. tonsa, with a 96 hour LC50 of 4.96 ug/1. Dunaliella tertiolecta was selected as the food source for the grazing experiments. Kepone concentrations of 0.046 ug/1 significantly (0.05 level) reduced the flltering rate …
