Fluorescent Tracer Mixing Experiments in Glenmore Reservoir, Calgary
Mixing studies using salt and dye as tracers were conducted in Glenmore Reservoir which is the major water supply for the City of Calgary, Alberta. The purpose of the studies was to find...
Economics and Groundwater
The increasing use of groundwater has resulted in greater lifts, and coupled with increased energy costs is focusing more attention on the economics of groundwater use. The proceedings...
Evaluating Pump Characteristics in Developing Countries
How do you assess normal operating characteristics for pumps used in small water supply systems when no information on the pumps is available and when the technicians have little technical...
Research Needs Related to the Nation's Infrastructure
The engineering community, which designs and constructs infrastructure facilities, must look for innovative ways to do a more efficient job. Although some research has focused on problems...
Infrastructure Crisis: What the Media Are Saying
In the past year and a half the national media have performed the major role in spreading the word that the nation's public works, particularly in urban areas, have been neglected...
EPA's New Land Disposal Rules�A Closer Look
Despite some initial enthusiasm for the new EPA regulations on land disposal of hazardous waste, many critics are now expressing concern for the long-term environmental impact. The dependence...
Analyzing Infrastructure Condition�A Practical Approach
New York City and Philadelphia are using a new method of analyzing existing data to develop sensible, economical water main replacement programs. By analyzing readily available data on...
Arizona's Water Strategy: Bring More In and Restrict Its Use
Decades of pumping groundwater faster than the natural rate of replenishment have lowered Arizona's water table to record depths and caused land subsidence and fissures. The...
Boston Tunes Up Water System
In 1977, Boston's water supply system had so many leaks and so many unmetered or undermetered customers that only about half the water entering the system was accounted for....
Water Supply
In 1982, the Washington Metropolitan Area took steps to optimize its water supply for the next 50 years or more. Using state-of-the-art water resource management techniques, the local...
