Page 6784 - Students of sanitary science have attempted to establish certain standards of purity of water based on the determination of nitrogen. These standards express limits for organic nitrogen, or albuminoid ammonia, free ammonia, nitrites and nitrates, beyond which the water containing them should not be used for drinking. Some of them have, the sanction of sanitary congresses, and some are merely the expression of individual opinion. The application of these standards of purity has condemned many waters...
Page 6782 - It is not possible to decide absolutely upon the wholesomeness or unwholesomeness of a drinking water by the mere use of any of the processes examined for the estimation of organic matter or its constituents.
Page 6779 - Fourth, that this tax is due, not to any peculiar condition of soil, locality, or climate ("endemic" factors), but to incomplete disinfection of typhoid excreta, with subsequent infection of various articles of food and drink.
Page 6969 - And the said party of the second part, for himself, his executors, administrators, and assigns, does hereby covenant and agree, to and with the said parties of the first part, their successors and assigns...
Page 6782 - I would even go further, and say that, in judging the sanitary character of a water, not only must such processes be used in connection with the investigation of other evidence of a more general sort, as to the source and history of the water, but should even be deemed of secondary importance in weighing the reasons for accepting or rejecting a water not manifestly unfit for drinking on other grounds. '• 3. There are no sound grounds on which to establish such general ' standards of purity,' as...
Page 6783 - In the majority of cases, chemical examination alone cannot be relied upon as giving conclusive evidence as to the suitability of a water for drinking. Of course, if a water is hard, the chemist can say, without hesitation, that the water is unsuited for supply on account of its probable effect on steam boilers, and because it will be uneconomical for use in washing. If the water contains arsenic or lead or other poisonous metal, the chemist can discover it. If the water is grossly polluted, or...
Page 6783 - ... and secondly, the periodical examination of a water supply, as of a great city, in order that, the normal or usual character of the water having been previously ascertained, any suspicious changes which from time to time may occur shall be promptly detected...
Page 6695 - ... alkaloid. It is not easy to believe that the ptomaines, or other chemical products of putrefactive change, can be so much more •poisonous than the strongest of recognised poisons. While most of the mischief in drinking water is probably attributable to living organisms, the possibility is noted, that indirectly a large amount of organic matter in water may be more dangerous than a smaller quantity, as furnishing on a greater scale the suitable material and conditions for development of organisms....
Page 6695 - Nos. 35 and 36, of the highly dangerous character of which there can scarcely be a doubt, existed as strychnine, it would be necessary to drink about half a gallon of the water at once in order to swallow an average medicinal dose of the alkaloid. It is not easy to believe that the ptomaines, or any other chemical products of...
Page 6778 - ... these five cities we find typhoid rates of 13, 16, 20, 25, and 25. We are confident that these rates are not raised by pollution of the public water supplies and that the influence of private well water upon them is negligible. It therefore follows that typhoid deaths ranging from 15 to 25 per 100 000 are due in these cities to causes other than polluted water; and it is probably fair to assume that at present in similar American communities about this amount of typhoid fever may be expected...
