The intent of this discussion was to get us connected with the on-going C-8 related activities in CRG and to explore ways to create synergy between the efforts in Ruoroproducts SBU and CRG- The effort in CRG is aimed at identifying and developing technology in removing or containing C-8 in groundwater or leachate of solid waste discharged.into river. , Ron mentioned that the C-8 level in the groundwater from monitoring wells at Washington Works ^ has been determined to be around 50-200 ppb. The test on the leachate w ater from Letart landfill (next to Washington Works) has shown that the C-8 level is at 2-3 ppm. Therefore their current focus is to find a way to remove very low level of C-8 in Water. Based on experiments performed at Experimental Station recently, both activated carbon and peat moss are effective m reducing C-8 in water down to several ppb level. They are still in the first phase concept development stage. They will need to follow-up the initial leads and further quantify the effectiveness of different types of C-8 absorbents. 1can see that the on-going C-8 remediation related work in CRG can be additive to the on-going C-8 containment effort in the following ways: 1. Selection of most effective absorbents in treating waste water containing low level of C-8. 2. Further broaden our knowledge and approach in dealing with C-8 containing waste streams. Ron has taken steps to ensure that we are closely connected such that CRG and our SBU can benefit from each other in C-8 removal expertise. RJZO14232 J EID937918
