摘要:

Urban environments are undergoing rapid change as a result of a variety of environmental stresses. Rapidly growing population density, aging water treatment and distribution facilities, and toxic chemicals in urban runoff will combine to increase the stresses on existing water supplies. In the future, we can expect waterborne pathogens such as Giardia, Legionella, and Cryptosporidium to be joined by hybrids of themselves and by as‐yet‐unidentified bacteria and viruses. Retraining utility personnel will be imperative as we incorporate new technologies to ensure water quality. The pressure on water suppliers to protect public health requires new forms of interagency cooperation. Water departments and public health departments must engage in collaborative planning efforts.

摘要:

The US Environmental Protection Agency (US EPA) has been attempting for several years to set a maximum contaminant level (MCL) for radon in drinking water. On July 18, 1991, US EPA proposed National Primary Drinking Water Regulations for six radionuclides, including radon. Most of the more than 600 sets of public comments submitted in response to this proposal focused on radon. US EPA's proposed MCL of 300 pCi/L for radon in drinking water has received severe criticism. There is widespread agreement among state health and radiation protection agencies, the scientific community, water suppliers, and other federal government agencies that the US EPA has overestimated the incremental benefits associated with the proposed MCL, while it has underestimated the cost of compliance. Following the close of the public comment period in November 1992, US EPA began to evaluate the proposal and prepare a response to the comments in order to develop a final rule. Concern remains regarding the rationality of the proposed MCL for radon. At the time of proposal, USEPA was under a court order to publish the final radionuclides rule no later than April 1993. This article focuses on developments and chronological history since the proposed rule was published.

摘要:

The value of detailed emergency plans became clear last summer to managers of drinking water utilities in Missouri, Illinois, and Iowa.In 1993, massive flooding threatened midwestem drinking water treatment plants. In this article, the author reviews the experiences of four utilities—three of them subsidiaries of American Water Works Service Co. (AWWSC). AWWSC's Iowa‐American plant in Davenport was threatened, but it was never in immediate danger because it had recently built facilities above the 5000‐year floodplain. However, both Missouri‐American and Illinois‐American were stricken. Local workers in both places solved problems using equal parts of creativity and perseverance: in addition, AWWSC's New Jersey headquarters office supplied expert assistance. by telephone, computer, and an on‐site crisis team. A fourth plant, Des Moines Water Works, had no headquarters office to turn to, but its 235 employees efficiently staffed vital operational and engineering support teams. Meanwhile, General Manager L.D; McMullen spent 4 hours a day answering questions from the media. Officials at all four utilities noted the importance of planning and coordination to successful resolution of the crisis. In addition, they all stressed the value of communication among staff members and with the public.

摘要:

L.D. McMullen recounts the hour‐by‐hour drama of how the Des Moines Water Works battled the rising Raccoon River and restored water service to residents last summer.Teamwork and communication saved the day last summer for the Des Moines Water Works. Massive flooding shut down the plant in mid‐July and left 250,000 people without drinking water. The utility had been thought to be safe; 25‐ft levees separated it from the Raccoon River, and the previous record flood level had been 19.5 ft in 1947. Last summer, though, the river crested at nearly 27 ft. Utility employees, their efforts to protect the plant unsuccessful, turned their attention to equipment repair and restoration of service. Utility General Manager L.D. McMullen describes how employees met the stated goal of “seven days to pump; thirty days to drink.” He credits the utility's team structure, regular communication among workers and between the utility and the public, and support from citizens, employees' families, local businesses, and suppliers.

摘要:

Hurricane Andrew ravaged southern Florida and left emergency planners with plenty of food for thought.The enormously destructive Hurricane Andrew flattened southern Florida last year and left a quarter of a million people homeless. Its co: is estimated to be $20 billion—an estimated $100 million of that damage to drinking water systems. In this wide‐ranging report, the author describes the frustrating range of problems water professionals faced a they began the lengthy process of recovery. The problems were legion, ranging from “uprooted” water mains and debris‐laden flood control canals to useless radio communication systems disabled because anten nas above the roof line had been knocked out. Bookkeeping became impossible because addresses no longer existed. Some employees wer injured; many lost their homes. AWWA's Florida Section offered finan cial help, and water professionals from unaffected utilities lent their expertise. This inventory of problems faced and solutions discovered will provide helpful ideas to emergency planners for water utilities.
