This will result in 8 soils samples per <br /> 3 . 7 cubic yards of soil. Submittal of samples for <br /> laboratory analyses will be based on results of <br /> field screening with a photoionizing organic vapor <br /> analyzer. <br /> Upon health department authorization to continue excavation on <br /> July 30, 1990, Aegis will guarantee the submittal of a results <br /> report to the health department no later than August 13 , 1990. <br /> Attached is a copy of theinitialclosure report/work plan <br /> submitted by Aegis on July 25, 1990. <br /> GEOLOGISTS • ENGINEERS • GROUND WATER SCIENTISTS <br />
