Director LAWRENCE, KANSAS November 1, 1939 Athletic Department Kansas University Campus Gentlemen: We are reporting herewith the bacteriological analysis of the two samples from the swimming pool--one marked “east end" and one marked "west end", Both of these samples must be reported as in bad condition, in that organisms of the coliform group were found present in all of the five 10 c.c. portions end in all of the three 1 c.ec. portions examined. We would suggest that it may be desirable to overhaul the water purification installation, including the filter, and to provide for a reasonable chlorination. There have been a great many complaints during the past years with regard to overchlorination of the pool. We believe it is possible to maintain the pool free of coli and at the same time not maintain such a high chlorine residual that the water is objectionable to bathers, Very truly yours, DIVIL TATION Earnest Boyce EB: ME Engineer and Director
