THE CONDITION OF TROY WATER.

THE CONDITION OF TROY WATER.

It seems that the condition of the water supplying the citizens of Troy, N. Y., is not satis factory. Professor James M. Caird was recently employed by the Press company of that city to report on the state of the water, and it appears probable from the data furnished by that gentleman that a system of filtration must be adopted without delay. The report is as follows:

Troy, N. Y., July 28, 1906.—Troy Press com pany, Troy, X Y.—Dear Sir: Agreeably to your request of July at for an analysis of the city water, lower service, permit me to submit the results of an analysis of water drawn from a tap on July 23. 1906. The pumping station has not been in operation since about May 1. hence, the

supply is being obtained from the Tomhannock system. The results follow :

From laboratory “tap” No. 271 River street

Sample taken July 23, 1906.

Results in Parts Per Million.

By referring to the results it is seen that the water has a color of 22 and a turbidity of 25 parts per million, and also carries considerable sediment, which deposits quickly. The appearance of this water cannot be called satisfactory. I am of the opinion that this condition would be greatly improved if the mains were systematically “blown off.” The water is “soft” and well saturated with oxygen. The “fishy” odor and taste are due to a vegetable micro-organism -known as algae. A list of those found and their number per cubic centimetre follows:

The most objectionable algae from an odor and taste standpoint, in the above table, are asterionella, anabaena, volvox and fragilaria. The application of copper sulphate in proper amount to the water in the reservoirs would destroy the algae growths. The use of a water containing algae, although offensive and disagreeable, will have no injurious effect upon the health of the consumer. The results for free and albuminoid ammonia arc rather high for a water in this locality. The number of bacteria per cubic centimetre is also high. The presence of the bacillus coli communis (in to c. c. samples) indicates that some of the bacteria are of “intestinal” origin. While the quality of the Tomhannock water is far superior to that of the Hudson river, formerly used, it cannot, under present conditions, be safely recommended for drinking purposes. Respectfully submitted.

At Landing, near Lake Hopatcong, N. Y., the nitro-cotton house of the F’orcite Powder company was gutted by fire, the cause of which is unknown. It totally destroyed the large brick and iron structure. It is supposed the fire sprung from spontaneous combustion, for nitro-cotton and soda were stored in the building. The superintendent called out the fire department of the plant: but for some time they were unsuccessful in getting a stream on the blaze, owing to bad spots in the hose. When they finally succeeded, they found that the water coming in contact with the soda caused explosions, and they were forced to desist, turning their attention to the adjoining buildings, which they saved.
