EDMUND JANES JAMES, PH.D., LL.D., President University of Illinois. SIR: Herewith I submit a report of the work of the State Water Survey for the year ending December 31, 1913, and request that it be printed as a bulletin of the University of Illinois, State Water Survey Series No. 11. The report contains an account of the work done by the Water Survey in accordance with the laws (Laws of Illinois, 40th General Assembly 1897, 12; 47th General Assembly, 1911, 43. Bulletin University of Illinois, State Water Survey Series, 9, 7-8). The General Report gives a summary of the chemical, biological and engineering work done and an account of the special investigations made during the year. Some interesting and valuable scientific investigations have been carried on by both the chemists and engineers. Advice relative to public water supplies has been given a large number of cities and plans for all new projects have been reviewed and reported upon. Extensive sanitary surveys of watersheds have been made which are proving of much value to cities facing the problem of sewage treatment. This work should be continued to cover all the watersheds of the state. During the year a co-operative arrangement has been perfected with the Rivers and Lakes Commission which increases the effectiveness of the Survey's work along the lines of stream cleaning. Thorough investigations have been made of several typhoid fever epidemics, suspected of being water borne. The most important of Health. During the Ohio River floods of April, the Survey was able to render valuable service in protecting water supplies and establishing sanitary conditions. Respectfully submitted, EDWARD BARTOW, Director.
EDMUND JANES JAMES, PH.D., LL.D., President University of Illinois. SIR: Herewith I submit a report of the work of the State Water Survey for the year ending December 31, 1912, and request that it be printed as a bulletin of the University of Illinois, State Water Survey Series No. 10. The report contains a summary of the work done by the laboratory and engineering divisions in accordance with the laws creating the State Water Survey and imposing upon it new and additional duties. (Laws of Illinois, 40th General Assembly 1897, 12; 47th General Assembly, 1911, 43. Bulletin University of Illinois, State Water Survey Series, 9, 7-8.) The report covers the first full year with the increased appropriation allowed by the 47th General Assembly. The special report by the engineering division shows the additional work accomplished and also confirms our belief that there would be a demand for the services of our engineering division. Several other organizations whose work is related in some way to the work of the State Water Survey is briefly summarized in the report. There are several articles that describe special experimental work and special investigations. Many cities have been visited during the year. The purpose of each visit, the observations made, and the recommendations, if any, are given. Thanks are due to the regular staff for their interest in the work of the Survey and to Dr. L. L. Burgess, Mr. O. Kamm, Mr. H. L. Olin, and Mr. C. H. Spaulding, for assistance rendered in the preparation of special articles. Credit is given in appropriate places for the part each has taken. Respectfully submitted, EDWARD BARTOW, Director.
SIR: Herewith I submit a report of the work of the Chemical Survey of the Water Supplies of Illinois, covering the years 1897 to 1902, inclusive. As was stated in my preliminary report, published in 1897, portions of which are incorporated in the present report, the aims of the survey include the determination of the present sanitary condition of the water supplies drawn from the lakes, the streams, and the wells of the State; the determination of the normal condition of uncontaminated waters; the formulation of local standards of purity based upon the results of analyses of water derived from unpolluted sources; the provision of such means as shall afford to citizens of the State opportunity to obtain immediate information regarding the wholesomeness of the potable waters in which they are directly interested; and in general the prevention of the development and dissemination of disease from the use of impure water. The press of work in certain of these directions has been so great that comparatively little has been accomplished in others, and a mass of data concerning the normal condition of ground waters must be left for digestion and discussion at some future time. The present report may be broadly divided into three parts, namely: 1. A brief consideration of the sanitary condition of the ordinary ground waters and matters relating thereto. Accompanying this there is a paper upon 'The Geology of Illinois as Related to Water Supplies,' by Charles W. Rolfe, Professor of Geology in the University. 2. Results of the mineral analysis of some four hundred and sixty samples of water mainly from wells of considerable depth. 3. A report of the investigation of the surface waters of the State, relating chiefly to the Illinois River and some of its tributaries. Most of the routine work of these investigations has been conducted by Mr. C. V. Millar, M. S., and Mr. R. W. Stark, B. S., to whom special commendation is due for the continued interest, the skill and the unfailing zeal with which they have furthered the purposes of the Survey. At various times we have further been ably assisted by Mr. F. C. Koch, M. S.; Mr. E. P. Walters, B. S.; Mr. A. D. Emmett, B. S.; and Mr. A. L. Marsh. Respectfully submitted, ARTHUR W. PALMER, Sc . D., Professor of Chemistry.
