Norwich bulletin., 1911-01-17

meeting to hear and consider the re-
 port of State Chemist J. A. Newlands regarding the Trading Cove brook wa ter and the watershed. As the result
 brook water will be purified and thtt 1t was not to be used until needed. there being sufficient water in Fair view and Mohegan lake to provide the present requirement for thirty days or more. Several requests were received for the permission to use elevators. but the board realized that while the restriction means inconvenience and possibly loss of business, yet on ac- count of the condition of Fairview they could not see their way clear to permit the use of the city water for elevator use as yet, and decided to wait until February 1st before taking action on the matter, in order to see what the condition is at that time. They. will not be allowed to use them at that time unless there is an im- prOvement in conditions
 Fairview on Monday showed a fur
 ther gain of two inches, being now just 22 feet below high water mark, l and having 46,000,000 gallons of water therein. or one-tenth of it's capacity.
 There are about six million gallons in Mohegan lake, which, with what is | coming in, will permit the pumping to continue there for about ten days
 more.
 Examination of the Water. The report of Chemist Newlands on the analysis of the Trading Cove brook water, taken from a point about mile above the pumping station on January 4, shows, as' he states, that the water contains a small amount of mineral matter and is quite soft. The organic constituents, with the exeep- tion of the oxygen consumed, are not high, and the chlorine is about nor
 nal.
 The number of bacteria growing on gelatin is moderately high, and organ isns of the E. coli type were isolated from five cubic eentimeters of the wa ter. While the presence of these or ganisms in small numbers is frequent ly only an indication of slight drain- age contamination from pasture land which might not be of any great sig nificance, recent inspection of a DOT ton of the drainage area indicates that contamination from barns and priviss is possible. The supply there fore cannot be passed as safe for drinking purposes without purifica- ton. The second sample,whic was taken from the brook at the new pumping station says the chemist, shows little difference in the general characteris- ties of this supply as compared with the sample taken from 2 point about a mile farther up the stream. The sup ply is more highly colored than your present supply, but aside from this there is little difference in the chem ical contents of the two waters. The bacteriolcgical results showed fhe presence of bacteria. Of the E. Coli type as in the other sample. indicat- ing contamination from some sourc ?. This water should not be used for drinking purposes without purifca- ton. ,T1 4J,- +.-;<, c. c. on gelatin at 20 degrees c. in IS hours numbered 1,170, and in the sec ond sample 920.
 Places. Which Menace Safety of Sup ply.
 The following letter was received by
 Supt. Corkery from Chemist Newlands
 regarding his visit to the watershed
 and read to the board
 Middletown, Conn, Jan. F, 1911.
 MT. J. J. CorlSery. Supt. Water Dept, Norwich, Conn:
 Dear Sir: On January 8, in compli- ance with your request. the writer, with you, MT. c. E.. Chandler, city en- gineer, and Dr. N. B. Lewis, city health officer, visited a portion of the drain age area of Trading Cove brook the
 proposed auxiliary water supply for the city of Norwich
 The question had been raised as to whether certail places on the drain age area. now menace the safety of the supply for drinking purposes. and. if so. whether these places could be
 sa tisfactorily improved so that the water might be used with safety. The first place visited was that of MT. J. G. Ward. Here the priyy is located about two hundred feet from the brook and on quite level ground. The custom of burying the excreta each week in garden between the privy and the brook should be stopped in order to protect the stream
 A barn just west of the Ward prop | erty is located on level ground about two hundred feet from the brook, and this place could be made satisfactory without great expense.
 At the fork of the roads east of the Ward property there are three houses and 8 grist and saw mill At the C. l.. Palmer place. the barn is about two hundred feet from the brook and the drainage here could be satisfac torily cared for by covering the ma : nure pile in order to avoid wash dur ing wet weather. The privy is back of the house and will probably not af- feet the stream. The sink now drains but could be made satisfactory by the construction of a cesspool. At the Silas Lef1ngwell place the sink drain empties on to the road about a hun dred feet from the brook. The privy is on a level ledge about seventy feet from the main brook Both of these might be made satisfac ctory by the construction of water-t tight vault and 8 cesspool. Adjoining the privy and nearer the brook there is a horse shed used by patrons of the mill The shed is on the edge of an abrupt slope The grist and saw mill extend across the brook and the privy in this build ing is directly over the brook It was said that this privy was rarely used but it was evident from the appear ance of door which hangs oyer the waters edge that someone had very recently contaminated the stream. A 1 barn in which two horses are kept. is located east of the mill at the edge of the brook. Manure thrown into 1 the barn yard must contribute a con- siderable amount of contamination te 1 the stream during wet weather. On the opposite side of the stream 8 l sink drain from a house occupied by 1 Mrs. K. Dfetz is said to drain under- l ground to the brock. The priyy is l loca ted on slope about ten feet from 1 the edge of the brook Extensive 1 changes. would be necessary at these l places in order to protect the stream I and the enforcement of sanitary reg | uiations at the mill, where a consider. | the course of a year would be difficult | if not impossible.
 The next place visited was abou half mile west of the grist mill
 l known as the Albert Witter place. Tn,
 privy here is on a steep slope aboll eighty feet from the brook and con. I tamination of the stream during we
 weather undoubtedly occurs. The priv.
 could be placed in a mere satisfac
