摘要:

This article provides a brief overview of water utility operations in the Atlantic Provinces of Canada that inlcude Nova Scotia, New Brunswick, Newfoundland, and Prince Edward Island. Specifically, the article mentions two regulatory authorities in Nova Scotia that govern water utility operation, the Nova Scotia Water Authority and the Nova Scotia Board of Commissioners of Public Utilities. Also mentioned are various sources of revenue for the Halifax Public Service Commission.

摘要:

This article presents the AWWA Joint Committee Report on Recommended Practice for Backflow Prevention and Cross‐Connection Control. This manual is intended to supplement, not supersede, local laws and regulations. The purpose of this manual is to provide water purveyors and other persons responsible for public potable water supply systems with a guide to procedures for the following: protecting water supplies against contamination or pollution resulting from backflow of objectionable fluids through cross connections; protecting these supplies at the service connection by isolating within the consumer's premises pollution or contamination that may result from backflow through cross connections; and, providing the means whereby an industrial consumer may utilize a separate system for his industrial uses in order to prevent possible pollution or contamination of his internal potable water system.

摘要:

This article describes a convenient method for plotting and interpreting the results of deep well alignment tests. It is common in making alignment tests to obtain accurate field data and to reduce the readings with mathematical precision, only to interpret the results with vague or inadequate methods. The article describes methods used in making an alignment test of a deep well. The acquisition and mathematical reduction of field data are given briefly to provide background only, as the real intent of this article is to discuss the subsequent utilization of the data obtained.

摘要:

The application of microelectrophoresis for the determination of particle mobility requires that compensation be made for the phenomenon of electroendosmosis (or electroosmosis) that occurs in the cell. A liquid in contact with a surface such as glass may possess a potential with respect to the latter. If an electric field is applied to such a system, there will be movement of the liquid along the surface as a result of this potential. This streaming (electroosmosis) must be taken into consideration if the true electrophoretic velocity is to be measured. This article recommends that the complete velocity profile be substituted for the blood sample as a method for the calibration of the Briggs microelectrophoresis cells.
