![Public Analyst’s Laboratory, 67, Surrey Street, Sheffield. Report on a Sample of Drinking Water received from the Rotherham Corporation, on March 28th, 1899. Sample Mark :—“ No. 98.” Town Supply. Physical Characters. Suspended Matter, None. Appearance of a Column two feet long, Clear & colourless. Taste, Normal. Odour, None. On Analysis, the sample gave the following results : — f Total Solid Matter, 25-48; which lost on Ignition S3 | 3-08 grs. Chlorine, 2-20; equal to Sodium Chloride, 3-62 grs. | Nitrogen in oxidised forms, 0*10; equal to Nitric Acid o | (anhydrous), 038 grs. ^Poisonous Metals (Lead, &c.) None. Degrees of Hardness, 18-0. [Each degree of hardness represents a soap-destroying power equivalent to one grain of chalk per gallon.] / Reducing Power, 0 33. [Representing the Oxygen « s [ absorbed by the organic and other oxidisable matters < in one million parts of water.] I Free and Ureal Ammonia, 0-02 parts per million Albuminoid Ammonia, 0-06 parts per million. These results show the water to be free from other than normal trades of readily-changeable organic matter. The proportion of Chlorides is in excess of that usually met with in South Yorkshire drinking-waters of unexceptionable quality, and, together with the presence of nitrates, suggests infiltration of surface drainage or similar impurity.
