Book Description
The revolt against white rule in Rhodesia nurtured incipient local feminisms in women who imagined independence as a road to gender equity and economic justice. But the country's rebirth as Zimbabwe and Robert Mugabe's rise to power dashed these hopes. Using history, literature, participant observation, and interviews, Carolyn Martin Shaw surveys Zimbabwean feminisms from the colonial era to today. She examines how actions as seemingly disparate as an ability to bake scones during the revolution and achieving power within a marriage in fact represent complex sources of female empowerment. She also presents the ways women across Zimbabwean society--rural and urban, professional and domestic--accommodated or confronted post-independence setbacks. Finally, Shaw offers perspectives on the ways contemporary Zimbabwean women depart from the prevailing view that feminism is a Western imposition having little to do with African women. The result of thirty years of experience, Women and Power in Zimbabwe addresses what happened when a generation of African women deferred their dreams of empowerment.

Book Description
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.

Book Description
"Total Maximum Daily Loads (TMDLs) are required under Section 303(d) of the Clean Water Act (CWA) for water bodies that do not attain water quality standards after technology-based pollution control requirements are applied. While this provision has existed in the CWA since 1972, it was brought to the forefront through a series of citizen suits in the 1980's and 1990's which required states and the United States Environmental Protection Agency (US EPA) to list water bodies not attaining water quality standards (so-called 303(d0-listed water bodies) and develop maximum loadings as necessary to meet water quality objectives. ... This project explores the benefits of drinking water utilities' involvement in the TMDL process. ... The Awwa Research Foundation (AwwaRF) and the Water Environment Research Foundation (WERF) sponsored an experts workshop ... held at River Club, Scituate, MA on December 11-12, 2003." -- Executive Summary, p. xv.
