Tha highest Individual atapla of 7.2 flbere/al, aad the highest tlaa weighted average of 3.0 lbar#/al wara oa Larry Jaaaa at tha dry blender. Sacaad waa Berwaa Dodd oa tha wat atzar with a tlaa weightad average of 1.7 fibere/al. All tha others vara uader ooa flber/nl. Saapla Mo. 59 oa Larry Jaaaa waa aot counted because of aa axcaaa of daat. Largs quantities of alca aad ether aeterlale ohacurad tha asbestos fibers asking it inpossible ta aahe aa accents taunt. Tha reason for tha high dwat level oa this particular filter waa daa ta tha length of tins (3 bra., 38 aiaa.) it waa collect leg daat. Tha ether four aaaplaa shared a period of foar hours. The tlaa weighted average la baaed oa this feer-howr period. It is raaeoaabla to asauaa that this parted uhtah waa froa 7:08 a.a. to 11:08 a.a. waa repre sentative of a full day epegetiaa. Ia tha future va should liait tha saapla tlaa oa tha dry hiaa Bar an ta 40 aioutea aaxiaua. This will require seven or eight filters. Boas ef the others s saplad, such aa the foresaw, can be allaiaatad or Just fft checked with one saapla. Tha two areas at Marlatta which need full saapla coverage are tha dry blander and the ready nix sixer. GWC;elx Enclosure* G. U. G.
