What reading level is Water And Water Supplies book?
To quickly assess the difficulty of the text, read a short excerpt:
If organic matter be present in appreciable quantity — that is, if the water yield such a quantity of organic nitrogen and carbon, or albumenoid ammonia, or requires such an amount of permanganate for oxidation as to render it of suspicious or of doubtful purity — a study of the history of the water and of its geological source may, and generally does, enable an opinion to be formed as to the nature of the organic matter, and as to whether it is of an innocuous or dangerous charac- ter. Chemica...l analysis, therefore, has its use; it is only when it is made the sole arbiter between safety and risk that it is abused, and is liable to lead to errors fraught with most disastrous consequences. Let the analysis be as careful and complete as possible, but let the results always be inter- preted in the light afforded by a searching examination of the source of the sample. Let all so-called standards be abandoned as absurd, and let the opinion as to whether a water is dangerous or safe be based upon a full consideration of other and more important factors.
