摘要:

The Supreme Court of Nevada ruled that a water utility was entitled to damages for its condemned water system. The court said that any award must represent the fair market value of the real property taken from the utility.

摘要:

This article discusses a new program to establish standards for all drinking water additives from a health effects point of view. The National Sanitation Foundation, the American Water Works Association Research Foundation, the Association of State Drinking Water Administrators, and the Conference of State Health and Environmental Managers have been involved in efforts to establish these standards. The goal is to develop standards for anything that comes in contact with drinking water, so that the drinking water industry and its suppliers can be assured that nothing harmful is delivered to consumers inadvertently.

摘要:

Public health is severely affected by inadequate water supplies in Micronesia, a vast island‐dotted area of the Western Pacific that had been held in trust by the United States from the end of World War II until recently. Many residents of the islands rely on catchment of rainwater for supplies; others are served by deteriorating systems carrying untreated water. The difficulties of coping with water demand and upgrading water service in such a remote and varied tropical location are discussed.

摘要:

As the United Nations Drinking Water and Sanitation Decade unfolds, donor organizations have found severe shortcomings in the operation and maintenance of water facilities in less developed countries, thus rendering service to the people less than anticipated. The authors analyze the reasons for inadequate or improper maintenance and offer suggestions for improvement to help meet the goals of the decade. In addition to recommending greater emphasis on operational problems during the design stage, the development of management systems and trained personnel is stressed.

摘要:

A fire at a chemical manufacturing plant near Basel, Switzerland, in November 1986 released tons of toxic materials into the vital Rhine River, killing hundreds of thousands of fish and affecting other aquatic life. Although the response to the accident was not immediate, Europeans were well prepared. The plume of contamination was systematically monitored as it descended past Germany and France to the Netherlands. Drinking water utilities were prepared to shut down intakes, if necessary, because the Rhine water is pretreated and allowed to settle for days in wells before final treatment and distribution. Actual damage from the spill was thus limited, and the river recovered within a week of the accident. Water utilities in the United States are advised to take comparable precautions if supplies from similar industrialized river basins are used.

摘要:

Wet and contrasting arid regions characterize the Iberian Peninsula, thus presenting challenges to water planners. Recently, the government of Spain promulgated laws, similar to those in the United Kingdom, that created river basin water authorities. Now, instead of most of the water resources of the country being under the control of large landowners, the resources have been put in the public domain. In addition, many new impoundment projects are under construction or have recently begun operation. These actions are expected to alleviate the difficulties in meeting growing water demands for urban areas as well as for irrigation of farmlands and production of hydropower.

摘要:

This article describes the overall development, including formulation and calibration, of linear and nonlinear multiple regression models for predicting total trihalomethane formation potential and kinetics during the chlorination of natural waters. The rationale behind each model formulation is discussed, and statistics relating to the calibration of each model are presented. The testing and attempted validation of these models are also addressed. Each model is subjected to a sensitivity analysis and a validation analysis using data derived from the literature.
