PRATHER PRATHEDS EP 863-2189 ( ZIPFEL ) ( BILLYRA ) Roger, Ron Billy stopped in my office today with results from the water analyses we took in Teflon last week- The results are as follows 1-29-97 bidg 124 D-M water 1-29-97 FEP D-M water UG/L UG/L 2,5,12 <1,<1,<1 <1 <1 <5 The samples you already had were analyzed as follows... 1-24-97 recycle tank D-M water UG/L Ca 57 Na 5 1-24-97 dilute C8 tank D-M water UG/L 225 27 As we discussed on the 29th, our analyses of Demin water at the Power House show no contaminants at detectable levels. Ron Billy and I EID929561 discussed the possibility that some contamination may come from the atmosphere. If so our tanks are open to the atmosphere. are going to sample the effluent from both of our tanks. Ron and I This may lead us to some other conclusions. Ron and I also thought we remembered that the line we sampled the DM water from in Bidg 124 was galvanized. Are we mistaken, or was the line actually galvanized? If you have metal pipe in demin service made of anything other than stainless, this may cause you trouble. I hope these you problem. results Give me are of a call some help to you in your quest to and we can discuss this further. solve I will also forward the lab results to you via the plant mail.
