Not illustrated. 1909 Excerpt: ... 4.---Average difference between dissolved solids and the sum of the constituents. Parts per million. The figure for total solids is the higher in more than 90 per cent of the analyses, a condition showing the presence of organic matter and undetermined constituents. Ten parts excess of total solids is not uncommon, especially in highly colored waters, but 10 parts excess of the sum of the constituents is unusual in waters running below 200 parts per million of solids, and results of that character should be carefully examined for error. The excess of total solids over the sum of the constituents may be 10 to 15 parts in a sample containing 100 to 200 parts per million of solids, if much organic matter is present; it may be higher in highly sulphated or chlorinated waters, especially with a high sodium base, but it does not usually exceed 10 to 15 parts in ordinary carbonated waters, even in those containing as much as 300 parts of total solids. The average differences between total solids and the sum of constituents in analyses of waters that had been treated with aluminum hydrate as described on page 14 were somewhat less than the differences on untreated waters from rivers containing water of similar character, and excesses of the sum over the total solids were somewhat more common. Inasmuch as the waters treated in this manner were high in organic matter, most of which was removed by the aluminum hydrate, the facts just detailed seem to corroborate the belief that much of the difference between total solids and the sum is due to organic matter; but the evidence on this point is not conclusive. ERROR OF COMBINING VALUES. METHODS OF COMPUTATION. The accuracy of the analyses was also checked by comparing the combining weights of the acidic and the basic ra...
