01/16/2001 08:28 AM To: Mary A Kaiser/AE/DuPont@DuPont cc: (bcc: Barbara J Dawson/AE/DuPont) Subject NMS Results M ary, H ere are the data that I have received thus far. As we discussed, I would appreciate if you could discuss the results with N M S. M y contact there is M att McMuilin (800-522-6671). At the suggestion of Robin Leonard, I used one h alf o f the detection lim it (5 ppb) in the data analyses. There are still a few which show a detection lim it o f 4 0 ppb - 1had asked the lab to reanalyze those sam ples and haven't gotten another set back. There are still 8 other samples fo r which I have gotten no results (#640994 - 641001). Ronk3 vli Please let m e know what you find. Thanks! Barbara
