Download or read book Air Pollution and Freshwater Ecosystems written by Timothy J Sullivan and published by CRC Press. This book was released on 2014-11-20 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: A practical book for professionals who rely on water quality data for decision making, this book is based on three decades experience of three highly published water and watershed resource professionals. It focuses on the analysis of air pollution sensitive waters and the consequent effects associated with soil and water acidification, nutrient-N enrichment, or the effects of atmospherically deposited toxic substances. It also covers lake zooplankton and/or stream macroinvertebrate biomonitors. Explanations of the reasons behind various recommendations provide readers with the tools needed to alter recommended protocols to match particular study needs and budget.

Download or read book Optimal Treatment Levels of a Stream Pollution Abatement System Under Three Environmental Control Policies written by Anthony V. Fiacco and published by . This book was released on 1979 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The existing approaches to the mathematical modeling and optimization of a water pollution problem are briefly surveyed. A proposed geometric programming model of a water pollution and treatment system, which easily lends itself to the theory and application of nonlinear programming sensitivity analysis techniques, is studied in detail. As in previous work by the author of the model, the optimal waste treatment facilities along the Upper Hudson River are presented for three different environmental policies, leaving the sensitivity analysis study for a following report. Previous results were obtained using a geometric programming code, while the present study makes use of the SUMT code. It is shown that the policy of fixed dissolved oxygen requirement yields the mininum annual waste treatment cost, relative to two other policies. Moreover, it is shown that a variable dissolved oxygen policy yields relatively uniform treatment levels in the treatment plants at appreciabley reduced cost compared to the costs involved in strict uniform treatment policy. the results of the present study are consistent with, but not identical to, the finding reported in previous work. The discrepancy in the coefficients involved in the dissolved oxygen constraints used by these two studies is the main reason for the differences observed. A listing of a computer program developed to calculate these coefficients is included. (Author).

Download or read book Water Pollution Modelling Measuring and Prediction written by C.A. Wrobel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water Pollution is a subject of growing concern in our industrial world. The environmental problems caused by the increase of pollutant loads dis charged into natural water systems have led the scientific community to pursue studies capable of relating the pollutant discharge with changes in the water quality. The results of these studies are permitting industries to employ more efficient methods of controlling and treating the waste loads, and water authorities to enforce more strict legislation regarding this matter. The present book contains edited versions of the papers presented at the First International Conference on Water Pollution (Modelling, Measuring and Prediction), held in Southampton, England, in September 1991. Its contents, which reflect the interdisciplinarity of the subject, are divided into four parts, each consisting of a keynote address and several invited and contributed papers: 1. Mathematical models (Keynote speaker: Prof. R.A. Falconer, Univer sity of Bradford, USA) 2. Data acquisition/monitoring/measurement (Keynote speaker: Dr. A. Plata Bedmar, IAEA, Austria) 3. Waste disposal and wastewater treatment (Keynote speaker: Prof. D.R.F. Harleman, MIT, USA) 4. Chemical and biological problems (Keynote speaker: Dr. E.I. Hamil ton, Environmental consultant, UK) Although the papers have been typographically edited they have been re produced directly from material submitted by the authors, and their content is a reflection of the authors' research and opinion.

Download or read book Water Pollution written by Allen V. Kneese and published by Routledge. This book was released on 2015-06-18 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Public agencies and industry will probably spend tens of billions of dollars on new water pollution abatement facilities in the next few decades. Added billions will be spent for the operation of new and existing facilities. How can physical science research reduce the cost of achieving objectives? And how can social science research make sure that the right objectives are being efficiently pursued? This title, first published in 1962, is directed to the orientation of the research effort, and the tool used for this purpose is an economic framework. This book will be of interest to students of economics and environmental studies.

Download or read book Assessing the TMDL Approach to Water Quality Management written by National Research Council and published by National Academies Press. This book was released on 2001-07-24 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last 30 years, water quality management in the United States has been driven by the control of point sources of pollution and the use of effluent-based water quality standards. Under this paradigm, the quality of the nation's lakes, rivers, reservoirs, groundwater, and coastal waters has generally improved as wastewater treatment plants and industrial dischargers (point sources) have responded to regulations promulgated under authority of the 1972 Clean Water Act. These regulations have required dischargers to comply with effluent-based standards for criteria pollutants, as specified in National Pollutant Discharge Elimination System (NPDES) permits issued by the states and approved by the U.S. Environmental Protection Agency (EPA). Although successful, the NPDES program has not achieved the nation's water quality goals of "fishable and swimmable" waters largely because discharges from other unregulated nonpoint sources of pollution have not been as successfully controlled. Today, pollutants such as nutrients and sediment, which are often associated with nonpoint sources and were not considered criteria pollutants in the Clean Water Act, are jeopardizing water quality, as are habitat destruction, changes in flow regimes, and introduction of exotic species. This array of challenges has shifted the focus of water quality management from effluent-based to ambient- based water quality standards. Given the most recent lists of impaired waters submitted to EPA, there are about 21,000 polluted river segments, lakes, and estuaries making up over 300,000 river and shore miles and 5 million lake acres. The number of TMDLs required for these impaired waters is greater than 40,000. Under the 1992 EPA guidance or the terms of lawsuit settlements, most states are required to meet an 8- to 13-year deadline for completion of TMDLs. Budget requirements for the program are staggering as well, with most states claiming that they do not have the personnel and financial resources necessary to assess the condition of their waters, to list waters on 303d, and to develop TMDLs. A March 2000 report of the General Accounting Office (GAO) highlighted the pervasive lack of data at the state level available to set water quality standards, to determine what waters are impaired, and to develop TMDLs. This report represents the consensus opinion of the eight-member NRC committee assembled to complete this task. The committee met three times during a three-month period and heard the testimony of over 40 interested organizations and stakeholder groups. The NRC committee feels that the data and science have progressed sufficiently over the past 35 years to support the nation's return to ambient-based water quality management. Given reasonable expectations for data availability and the inevitable limits on our conceptual understanding of complex systems, statements about the science behind water quality management must be made with acknowledgment of uncertainties. This report explains that there are creative ways to accommodate this uncertainty while moving forward in addressing the nation's water quality challenges.
