Concentration And Distribution Of Phosphate In The Sediment Of The Charleston Side Channel Reservoir, Nancy A. Johnson Jan 1993

Concentration And Distribution Of Phosphate In The Sediment Of The Charleston Side Channel Reservoir, Nancy A. Johnson

Masters Theses

The Charleston Side Channel Reservoir (CSCR) is located on the southeast edge of the City of Charleston in Coles Co., IL. The CSCR is the sole source of public drinking water for the city and also provides for a variety of recreational activities. Water quality in the CSCR has deteriorated since its construction in 1981, leading to its classification as hypereutrophic. The presence of high levels of phosphate are of particular concern having contributed to an increase in algal blooms and high turbidity.

In order to assess the role of internal loading of phosphate from the sediment, thirty-five sample sites …

Larval Chironomids Of The St. Francis Sunken Lands In Northeast Arkansas, Betty G. Cochran, Edmond J. Bacon Jr., George L. Harp

Journal of the Arkansas Academy of Science

Sixty semi-annual collections (August 1987-July 1988) were made from 30 stations by sampling each station twice for 1.5 man-hours with an aquatic dipnet. Larval chironomids were mounted on slides and identified at 400-1000 magnifications using a Leitz Dialux 20 EB microscope. A survey of the aquatic macroinvertebrates of the St. Francis Sunken Lands in northeast Arkansas revealed 36 taxa of Order Diptera, Family Chironomidae. The taxa were used to evaluate the general health of the aquatic environment. Stations that were located within the least disturbed areas, which were old river channels and oxbows, contained the highest number of organisms and …

Southern Nevada Effluent Wetlands: A Proposed Cooperative Venture Between The Bureau Of Reclamation & City Of Las Vegas, Bureau Of Reclamation Nov 1992

Southern Nevada Effluent Wetlands: A Proposed Cooperative Venture Between The Bureau Of Reclamation & City Of Las Vegas, Bureau Of Reclamation

Publications (WR)

Throughout North America there is a growing interest in constructed wetlands, both as relatively inexpensive, low-maintenance systems for removing nutrients from wastewater, and as a means of using municipal wastewater to enhance wildlife habitat and create public use opportunities. Because wetlands appear to have good potential as a component in the overall management of scarce water resources, the Bureau of Reclamation (Reclamation) has undertaken several cooperative research and demonstration projects to evaluate their effectiveness in a variety of local environments. While a number of projects have demonstrated that wetlands can be beneficially employed to improve water quality, few such projects …

Arkansas Agricultural Chemical Ground-Water Management Plan, Gerald King, Darryl Little, Tim Jessup, Charles Armstrong Oct 1992

Arkansas Agricultural Chemical Ground-Water Management Plan, Gerald King, Darryl Little, Tim Jessup, Charles Armstrong

Arkansas Water Resources Center Technical Reports

The Arkansas Agricultural Chemical Ground-Water Management Plan (SMP) is based on the Draft State Pesticide Ground- Water Management Plan Guidance and The Pesticides and Ground-Water Protection Strategy prepared by the U.S. Environmental Protection Agency (EPA). The need for a plan to protect ground water from contamination by agricultural chemicals and agents arises from evidence nationwide that using these chemicals can, in some instances, lead to contamination. In February 1988, EPA proposed a strategy to regulate certain pesticides by prohibiting their use in areas vulnerable to leaching unless a state develops and implements an acceptable management plan. The advantage of a …

The Boston Harbor Cleanup, Paul F. Levy, Michael S. Connor Sep 1992

The Boston Harbor Cleanup, Paul F. Levy, Michael S. Connor

New England Journal of Public Policy

Boston Harbor earned a widespread reputation as "the dirtiest harbor in the nation" during the 1988 presidential campaign. Well before that campaign began, though, efforts were under way to reduce the amount of pollution entering the harbor. The Massachusetts Water Resources Authority was created in 1985 to undertake a massive public works program — including construction of a 1.3 billion-gallon-per-day sewage treatment plant and a sludge fertilizer processing plant — to end the decades-old practice of dumping sewage wastes into the ocean. The program will also cause water and sewer charges to rise dramatically during a fifteen-year period.

The project …

Testing The Role Of Technical Information In Public Risk Perception, Branden B. Johnson, Peter M. Sandman, Paul Miller Sep 1992

Testing The Role Of Technical Information In Public Risk Perception, Branden B. Johnson, Peter M. Sandman, Paul Miller

RISK: Health, Safety & Environment (1990-2002)

It is widely believed that more detail about health effects and likely exposure routes is apt to reduce citizens' concerns about low-probability Risks. The authors' study suggests that providing such detail may not be as useful as, e.g., addressing public concerns and keeping citizens current on officials' actions.

Risk Estimation And Expert Judgment: The Case Of Yucca Mountain, Kristin Shrader-Frechette Sep 1992

Risk Estimation And Expert Judgment: The Case Of Yucca Mountain, Kristin Shrader-Frechette

RISK: Health, Safety & Environment (1990-2002)

Professor Shrader-Frechette discusses factors responsible for acute disagreement between the federal government and Nevada citizens over potential Risks at Yucca Mountain and focuses on the use of expert judgment, concluding that some of them appear to exemplify "bad science." That aside, she argues that 1,000 year predictions cannot be made from current knowledge of geology or, e.g., institutional behavior and concludes that permanent disposal of radioactive waste is currently impossible.
