Machle Dear Dr. Machle: In your letter of March 26th you directed us to pick up samples of sludge from tanks that have been spiked. In the last paragraph you indicated that you vrere in no hurry to have these samples, from which I gathered this might he a long term research program on your part. How ever, in view of your recent report I am wondering if you feel this phase of your investigations has "been completed? If you do, we vail notify the safety engineers to discon tinue picking up these samples. Yery truly yours. Til; &CL KE 0022573
