摘要:

People in both water agencies and health departments understand not only the literal meaning but also the liability implications of a cross connection. A cross connection control program that does not include mandatory annual testing and maintenance of all devices by certified personnel is potentially a greater liability than no program at all.

摘要:

A penalty imposed by a Wyoming statute for installing or modifying a public water system without a permit was civil in nature, according to the state supreme court. Thus the court held that the defendants here were not entitled to rely on their right to remain silent on the basis that the proceedings were criminal.

摘要:

Increasing demand and decreasing raw water quality have plagued the treatment plants serving the Paris suburbs In recent years. These problems have been partly offset by Improvements implemented gradually at all stages of the treatment train, which make the most of the facilities already in place.

摘要:

All of the activities related to the safety and quality of potable reuse, involving a variety of disciplines, have been designed into Denver's program so that when technical and economic feasibility have been demonstrated, health professionals and the general public will be able to make intelligent decisions on the acceptability of potable reuse in Denver.

摘要:

The past decade has seen a dramatic change in attitude concerning the use of natural resources. We have come to realize that our nation's resources, including water, are finite, and that it is essential to examine the “need” for water in the face of increasing demand from all sectors and a precipitous rise in the cost of providing additional supplies.

摘要:

Hunter established values for the frequency and duration of water consumption at various residential fixtures. Because his estimates are now regarded as too high, use of Hunter's model may lead to oversizing of water supply piping.

摘要:

In estimating costs for utility compliance with the organics regulations, the Environmental Protection Agency developed capital and operations and maintenance cost designs for a series of unit processes, and presented them as a function of given design parameters. The cost data are intended to be sufficiently accurate for preliminary planning and flexible enough for cost effectiveness studies.

摘要:

Source surveys, source analyses, risk assessments, alternatives for dealing with contamination problems, cost‐benefit analyses, and full‐scale GAC treatment are among the practical strategies water utilities might use in meeting regulatory requirements for the control of synthetic organic contaminants in drinking water.
