University of Cincinnati Eden Avenue Cincinnati, Ohio Dear Dr. Kehoe: I believe that Ollie Jones talked to you on the telephone about a possible lead problem in connection with a number of tanks that now exist which are known as the Aqua System. Attached is a copy of a letter recently received from Lou Shank. You will note that he suggests that a further investigation might be in order in view of certain tests made at one of these instal lations. Before proceeding with an investigation program of any scope, we would first like to have your comments. Possibly you would prefer to sit down and talk it over together at one of our regular meetings. Cordially, EKL/rnf attach. (1) cc: Mr. H. K. Ball (2) N 7680
