Excerpt from Water Analysis for Sanitary and Technical Purposes In addition to waters from the above-named sources, the analyst has to deal with sewage, drainage from cultivated land, effluents from sewage works, polluted stream and river waters, effluents from various industrial works, &c., all of which may be examined by the same processes as are used in the analysis of waters for drinking purposes. The sanitary analysis of a sample of water is not a full analysis, nor is it necessary to estimate every constituent present in order to arrive at its suitability for drinking and general household purposes. The analysis is so arranged that it gives definite information upon the question whether a water contains sewage or other organic pollution, or any deleterious matters, such as poisonous metals, and this is done by apply ing special qualitative or quantitative tests for those which are injurious ingredients. In searching for pollution by organic matter, the amount of carbon and nitrogen present in the latter are estimated, and, in addition, some of the products into which organic matter is known to decompose by oxidation are determined. Though a complete analysis with a long list of figures looks imposing, still for sanitary purposes all that is required is to prove whether the sample Of water is fit or unfit for drinking purposes, and therefore the determinations can be narrowed down to a few tests which are absolutely essential. For an ordinary sanitary analysis the following estimations are made: Total solid matter, free ammonia, albuminoid ammonia, nitrogen as nitrates, nitrogen as nitrites, oxygen absorbed, and chlorine.
