It is our opinion that an SDRI test on the ML test pad (which contains more clay <br /> and fines than the SM test pad) would most likely indicate an even lower permeability. For this <br /> reason, we do not recommend further SDRI testing. We recommend the procedures outlined <br /> in our July 8, 1993 report be used for barrier construction. <br /> Copyright 1993 Kteinfetder, Inc. Page 4 of 5 <br />
