See the attached boring log and Summary of Soil Analytical Data. <br /> 12/16/93 Field work was initiated to drill and install two monitoring wells:, MW5 and MW6. No soil samples <br /> were submitted for laboratory analysis. See the attached{boring log. <br /> 1994 s <br /> Groundwater samples were collected from MW4-MW6.'l See the attached Summary of Groundwater. <br /> t Analytical Data, <br /> 3� <br /> 1995 <br /> 5/1/95 A limited excavation was attempted. Approximately 330 cubicykards of contaminated soil was <br /> removed and disposed of at Forward Inc. Remaining soil contamination was characterized by the <br /> seven soil samples that were collected from the sidewalls'and the bottom of the excavation, <br /> 8/21/95 Two additional soil borings(SB 1 and SB2)were drilled and sampled to further assess the vertical and <br /> horizontal extent of the contamination. See the attached boring log and Summary of Soil Analytical <br /> Data. ' <br /> } 1996 <br /> Groundwater samples were collected from MW 1 -MW6.��See the attached Summary of Groundwater <br /> Analytical Data. �' <br /> 11/1996 A Soil and Groundwater Modeling Report was prepared that included the results of the Vleach <br /> analysis. i <br /> 19971 <br /> 6/30/97 Groundwater depths were measured in the monitoring wells and a sample collected from MW4.
