' ' , ; College of Medicine, ; ' Eden Avenue, ,; ' CINCINNATI 19, ! Ohio, U.S.A. Dear Dr. Kehoe, I very much r egr et th at I seem to be burdening you with yet another le t t e r . This time, for t u n at ely, i t i s rath er sh ort and i s in th e form of a simple r equ est. I wonder i f you could p ossib ly inform me x^hether or not any in vest igat ion s have been done with regard to th e chemical an aly sis of buried slu dge. As I have previously expected, th e question i s now being r aised as to what might be found i f sludge buried sever al years ago follow in g tank clean in g i s dug up eith er for b u r ial of fu rth er sludge or for con stru ction purposes .'in the area of b u r ial. Any information which you may tave on t h is su bject would be . . gr eat ly appreciated. . We suspect th at such sludge w ill . : con tin ue.to con tain both t et r aet h y l lead and i t s breakdown products fo r many years when buried in t h is way, and we propose to do corin gs of one or two of th e older b u r ial grounds t o see i f we can form any p ict u r e .' Before doing so, however, we thought perhaps you might have had some experience in t h is matter which would prevent us having V t o repeat any known work. . . . . . >. .` With kin dest regar ds, . . / : ` / Tours sin cer ely,
