Kehoe, .Kettering Laboratory of Applied Physiology, /University of Cincinnati, , ' ; College of Medicine, ' Eden Avenue, ,; ' CINCINNATI 19, ! Ohio, U.S.A. Dear Dr. Kehoe, I very much regret that I seem to be burdening you with yet another letter. This time, fortunately, it is rather short and is in the form of a simple request. I wonder if you could possibly inform me xrhether or not any investigations have been done with regard to the chemical analysis of buried sludge. As I have previously expected, the question is now being raised as to what might be found if sludge buried several years ago following tank cleaning is dug up either for burial of further sludge or for construction purposes.'in the area of burial. Any information which you may have on this subject would be . . greatly appreciated. . We suspect that such sludge will continue.to contain both tetraethyl lead and its breakdown products for many years when buried in this way, and we propose to do corings of one or two of the older burial grounds to see if we can form any picture.' Before doing so, however, we thought perhaps you might have had some experience in this matter which would prevent us having ' to repeat any known work. With kindest regards, Yours sincerely, Kl/jMoiSA -T M . / t`-;\
