,nt: Wednesday, January 03. 2001 4:20 PM j: Fitzpatrick. Kevin Subject: Third Runway Fill Beth Clark called regarding the copper samples from the one site they want to use as a fill source. That is the site I flagged as over Method B copper for the protection of ground water. The new results, some 10 samples again show high copper values, -70 to 100 rng/kg. She questioned the use of Method B protectionof ground water. I repeated that was what we agreed on. She suggested we do not use the 100X ground water standard. I disagreed and reaffirm the std. She may call you later. AR 017292 EXH0020017292
