Excerpt from Sewage Pollution in the Metropolitan Area New New York City and Its Effect on Inland Water ResourcesIn a primeval country, undisturbed by the advance of civilization, where there are no houses, barns, or factories, the water that ¿ows from a drainage basin may be said to be normal. This, however, does not mean that the water is chemically pure. The water of precipita tion or rainfall, which is the origin of all surface waters, takes three courses, the proportion carried along each depending upon many physical characters and conditions. There is, first, that which is evaporated or absorbed by vegetation, second, that which runs off the ground directly into water courses, and third, that which sinks into the ground and reappears in various well-known ways after having filtered through the earth.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
