![Public Analyst’s Laboratory, 67, Surrey Street, Sheffield. Report on a Sample of Drinking Water received from the Rotherham Corporation, on January 5th, 1899. Sample Mark :—“ No. 96 Shallow Well.” Physical Characters Suspended Matter, None. Appearance of a Column two feet long, Clear & Colourless Taste, — Odour. None. On Analysis, the sample gave the following results:— f Total Solid Matter, 64-12 ; which lost on Ignition, S3 _ J 12-04 grs- ! Chlorine, 10-80; equal to Sodium Cloride, 17-82 grs. •§ gj I Nitrogen in oxidised forms, 1-40 ; equal to Nitric Acid o j (anhydrous), 5-40 grs. ^Poisonous Metals (Lead, &c.) None. Degrees of Hardness, 30-0. [Each degree of hardness represents a soap-destroying power equivalent to one grain of chalk per gallon.] Reducing Power, 0-72. [Representing the Oxygen ^ absorbed by the organic and other oxidisable matters ig < in one million parts of water.] Ij'l f Free and Ureal Ammonia, 0-03 parts per million. x Albuminoid Ammonia. 0-10 parts per million. These results show the water to have suffered extensive contamination by cesspool-drainage or similar impurity. The greater part of the polluting matter has subsequently undergone spontaneous destruction by oxidation, but such a water must always be regarded with the gravest suspicion. In my opinion, its use for drinking is dangerous, and should be wholly dis¬ continued. ALFRED H. ALLEN. January 7tH, 1898, 8-35 p.m. Well water, Mr. Robinson, Stable yard, Westgate.](https://iiif.wellcomecollection.org/image/b3004246x_0010.jp2/full/800%2C/0/default.jpg)
