This work is a continuation of a series of lectures and papers on the quality of public water supplies which the author has read before several scientific societies and in universities during the past five years, and presents briefly:
The facts and causes of pollution of sources of public water supplies.
The effect of this pollution on the typhoid fever rates of our larger cities.
Illustrates by few examples how typhoid rates have been reduced by the introduction of water from purer natural sources and by filtration of polluted water.
Data are given on the methods of construction and operation of sand filters with the cost of filter construction. In these days when health officers and sanitarians generally are deeply impressed with the importance and necessity of vigorous attack on the water pollution and the prevention of diseases arising from bad water, this work will be found of great value.
