Relative availability of selected trace elements from coal fly ash and Lake Michigan sediment

Description: The concentration of greater than 1 ..mu..m coal fly ash particles in Lake Michigan surface waters was found to be 10/sup 5/ to 10/sup 6/ per liter. With an expected residence time of one year, this concentration implies a flux to the sediment of 10/sup 6/ to 10/sup 7/ particles/cm/sup 2//yr, or about 10/sup -6/ to 10/sup -5/ g/cm/sup 2//yr. The release of trace elements from fly ash and sediment has been studied using Chelex-100 resin to simulate leaching at high dilutions in natural media. Mn… more

Plutonium and Americium Concentration Along Fresh-Water Food Chains of the Great Lakes, U. S. A. Progress Report, July 1976--September 30, 1977

Description: The primary purpose of studying the biogeochemical behavior of transuranic radionuclides in large freshwater lakes began with studies of the distribution of these radionuclides, essentially introduced from the fallout of atmospheric nuclear weapons tests, in Lake Ontario. The recognition that an additional source of supply of these nuclides to Lake Ontario (subsequent to their release into Lake Erie) existed in the form of leakage from the Nuclear Fuel Services reprocessing plant at Springville… more

Environmental status of the Lake Michigan region. Volume II. Natural areas of the Lake Michigan drainage basin and endangered or threatened plant and animal species

Description: The accelerating encroachment of human activity on the natural landscape has made many citizens appreciate the need to save representative biotic communities before urbanization and technologically induced change eliminate such communities. Active programs in natural-area preservation are now in progress in the four basin states; these programs have strong public support and legislative mandate. Local, state, and federal agencies and private individuals have taken an active interest in protecti… more

Feasibility of a district cooling system using natural cold water

Description: The findings of investigations into the use of natural cold water district cooling systems are outlined. Concepts involving the use of natural cold water for cooling commercial and residential buildings have been examined and found to be economically sound and technically feasible. Studies indicate that naturally occurring cold water sources exist in proximity to certain municipal areas that have large cooling demands. Savings in energy resources, long term cost benefits, and environmental safe… more

Water resources research program. Thermal plumes from submerged discharges at Zion Nuclear Power Station: additional prototype measurements of interacting plumes

Description: Measurements were made of the thermal plumes from the two submerged discharges of the Zion plant into Lake Michigan during the summer of 1976. The survey results are reported in the form of horizontal isotherm maps at vertical intervals of 1.0 m, from the surface to a depth of 3.0 m, and of selected vertical cross sections. Ambient lake-water temperatures and currents were monitored throughout the study period. Analysis of data from two mappings of double plumes made in 1975 by Argonne at this … more

Transport and transformation of pollutant in the Lake Michigan area. [Pollutants from the Chicago and Milwaukee areas]

Description: The transport and the transformation of pollutants emitted from the Milwaukee and the Chicago areas were studied during August 1976. The study is part of the MAP3S program sponsored by ERDA--DBER. The experiments were conducted in approximately Lagrangian frames of reference utilizing two instrumented aircraft and surface support units. It was found that: 1) build up of ozone downwind of the areas occurred; 2) sulfate concentrations were higher in the urban plume than those upwind, and progress… more

Water Resources Research Program: Pollution of Coastal Waters Off Chicago by Sinking Plumes From the Indiana Harbor Canal

Description: On March 2, 1977, during sinking-plume conditions, a portion of the water of the Indiana Harbor Canal (IHC) was injected with samarium and rhodamine-dye tags and a section of the IHC's surface was covered with simulated oily waste tagged with dysprosium. Water samples were taken downcurrent, over a 54-hr period, from a vessel and from the raw-water streams from the intakes at Chicago's South Water Filtration Plant (SWFP). Bottom currents and water temperatures were measured almost continuously … more

Nutrient enrichment and eutrophication of Lake Michigan. Progress report, November 1, 1971--September 30, 1977

Description: Data on mixing processes in the nearshore zone of Lake Michigan are presented. Emphasis was placed on an area near Holland, Michigan where typical summer mixing patterns of the Kalamazoo River plume between the nearshore zone and mid-lake water mass were studied. Results showed that the nutrient load of the river's tributaries studied had a marked effect on the nearshore zone and the standing crop and species composition of phytoplankton. Data are included on the content of phosphates, silica, … more

Water Resources Research Program. District heating and cooling utilizing temperature differences of local waters. Preliminary feasibility study for the Chicago 21, South Loop New Town project

Description: This report examines the feasibility of cooling and heating buildings of Chicago's South Loop New Town (SLNT) project by using cool Lake Michigan water and warm water from Commonwealth Edison Company's Fisk Generating Station. Three systems are considered for the heating/cooling requirements of the SLNT project: conventional, conventional with lake-water cooling, and modular heat-pump systems. Characteristics of the source waters and institutional constraints to their use are also considered. T… more

Cooling systems research at Argonne National Laboratory

Description: Studies of the thermal plumes resulting from discharges from once-through cooling systems of electric generating stations are reviewed. The collection of large amounts of water temperature data for definition of the three-dimensional structure of a thermal plume, of current data, and related ambient data for model evaluation purposes required the development of an integrated data collection system. The Argonne system employs measurements of water temperature over the water column from a moving … more

Dissolution of diatom frustules and silicon cycling in Lake Michigan, U. S. A

Description: Diatoms require dissolved silicon for the formation of the silicate frustule that surrounds the cell. Potential sources of this silicon include dissolution of frustules produced by previous diatom communities, inputs of dissolved silicon from land drainage, and dissolution of silicate minerals. Results are reported from investigations on the relationship between diatom-frustule production, sedimentation, and dissolution to determine the importance and the mechanisms of silicon recycling in a la… more

Great Lakes waters: radiation dose commitments, potential health effects, and cost-benefit considerations

Description: In 1972, a Great Lakes Water Quality Agreement was signed by the United States and Canadian Governments. It was stipulated that the operation and effectiveness of the agreement were to be reviewed comprehensively in 1977. Aspects of the agreement concern nondegradation of Great Lakes waters and maintenance of levels of radioactivity or other potential pollutants at levels considered as low as practicable. A refined radioactivity objective of one millirem is proposed in the Water Quality Agreeme… more

Observation of thermal plumes from submerged discharges in the Great Lakes and their implications for modeling and monitoring. [Zion, D. C. Cook, and J. A. FitzPatrick Nuclear Power Plants]

Description: Measurements of thermal plumes from submerged discharges of power plant cooling waters into the Great Lakes provide the opportunity to view the mixing processes at prototype scales and to observe the effects of the ambient environment on those processes. Examples of thermal plume behavior in Great Lakes' ambient environments are presented to demonstrate the importance of measurements of the detailed structure of the ambient environment, as well as of the plumes, for interpretation of prototype … more
