Book Description
The U.S. Environmental Protection Agency (EPA) was introduced on December 2, 1970 by President Richard Nixon. The agency is charged with protecting human health and the environment, by writing and enforcing regulations based on laws passed by Congress. The EPA's struggle to protect health and the environment is seen through each of its official publications. These publications outline new policies, detail problems with enforcing laws, document the need for new legislation, and describe new tactics to use to solve these issues. This collection of publications ranges from historic documents to reports released in the new millennium, and features works like: Bicycle for a Better Environment, Health Effects of Increasing Sulfur Oxides Emissions Draft, and Women and Environmental Health.

Book Description
The volume starts with comparative reservoir limnology and deals with problems relating to tropical, semi-arid and temperate reservoirs. The second part concerns mathematical models of reservoirs, including new techniques for investigating their limnology. These cover physical, chemical and biological phenomena, remote sensing and the use of modelling to establish the most efficient strategy for water quality sampling. In the third, on reservoir water quality management, the potential available in fish population management for biomanipulation of reservoir water quality is introduced. Also included is a valuable section on a wide range of water quality measures, coming from the well-known Czech Hydrobiological Laboratory. Finally the editors summarise the present state of reservoir limnology. This book will be of interest to hydrobiologists and aquatic ecologists, reservoir and sanitary engineers, fisheries officers, postgraduate teaching, and the water industry dealing with drinking water supply and will provide insight into regulated rivers. It draws information from all over the world and is relevant to the whole world.

Book Description
A clear, straightforward presentation of concepts and issues in aquatic pollution This comprehensive introductory text presents a systematic study of pollution in oceans, lakes, streams, and underground aquifers. In a clear, straightforward style that is easily accessible to nonscientists, it describes the sources, features, and effects of thirteen different types of aquatic pollution. Fully updated to reflect current understanding and recent developments, this Third Edition of Aquatic Pollution covers every aspect of pollution associated with urban runoff, acid rain, sewage disposal, pesticides, oil spills, nutrient loading, and more. Case studies of major pollution sites such as Lake Erie, Three Mile Island, and the Rocky Mountain Arsenal help to illustrate points made in the general discussion. Important features of this new edition include: * Updated discussions of nonpoint source pollution, industrial pollution, thermal pollution, pathogens, metals, plastics, and more * New case studies of Chesapeake Bay and the Exxon Valdez * Beginning-of-chapter outlines * End-of-chapter study questions * New special section on units of measurement * Four chapters on the fundamentals of ecology and toxicology Aquatic Pollution, Third Edition, is a first-rate teaching and learning tool for courses in environmental science, zoology, oceanography, biology, and civil or sanitary engineering. It is also an excellent primer for policymakers and activists focused on environmental issues.

Book Description
Eutrophication is a problem which became widely recognised by the scientific community in the 1940s and 1950s. It raised public concern, resulting in increased research effort and expenditure on management techniques through the 1960s and 1970s, recognised as a distinct problem of water pollution, though linked with the more gross effects of organic pollution. In the 1980s it became less fashionable - replaced in the public's eye and the politician's purse by newer problems such as acid rain. It remains however, one of the biggest and most widespread problems of fresh waters, particularly of lakes and an increasing problem for estuaries and coastal waters. It is one with which almost all water scientists and engineers in urbanised areas of the world have to cope. Technical methods for the reversal of eutrophication, such as nutrient removal, have been developed and applied successfully in some instances. They are not widespread however, and where they are feasible, they are often expensive and may be politically difficult to implement. In the last decade, attention has focussed upon less expensive lake manipula tion techniques, such as destratification and biomanipulation, which aim to minimise rather than elimininate the detrimental effects of eutrophication. These are becoming more widely applied. Prediction of the potential problems in lakes and catchments which have not yet suffered the full effects of eutrophication is now accurate enough to be of direct benefit to river basin management.
