OCT E_ 16' 1D LE-1.1DIF, -F'ICI;:E,H E'. - <br /> LEVI N E•FRICKE <br /> be discussed here, but will be addressed in detail in our report. <br /> OBJECTIVE <br /> The major objective of the Environmental Site Assessment is to <br /> identify possible environmental concerns at the Sites, assessing <br /> potential problems relating to chemical application, leakage, <br /> spillage, discharge and disposal. Such problems could be the <br /> result of present or past operating practices at the Sites, past <br /> land uses prior to the current ownership of the Sites, or migra- <br /> tion of chemicals onto the Sites from neighboring properties. <br /> Given the apparent historical agricultural usage of both proper- <br /> ties, the primary focus of the assessment would be on agricul- <br /> tural chemicals associated with such use. <br /> PROPOSED SCOPE OF WORK <br /> The revised proposed Scope of Work for Task 5, Sampling of Soil <br /> and Ground Water, and Task 6, Laboratory Analysis is summarized <br /> below. <br /> Task 5s Conduct Sampling of Soil and around Water <br /> Random Samolina <br /> For purposes of assessing the presence of agricultural chemicals <br /> used in the field areas of the Site, the site will be divided <br /> into eight units, based roughly on crop history and parcel <br /> lines. From four to five shallow soil samples will be collected <br /> within each unit at depths of approximately 1 foot and 3 feet <br /> below grade using hand-angering equipment. Portions of the <br /> 1-foot samples collected from each unit will be composited by the <br /> laboratory for analysis. The remainder of the individual soil <br /> samples collected from each unit will be retained by the labora- <br /> tory for possible future analysis. The samples collected at 3 <br /> feet will be held by the laboratory pending the analysis results <br /> of the 1-foot samples. <br /> Targeted Sampling <br /> Subsurface soil and/or ground-water samples will be collected <br /> from a total of 15 deeper borings targeted to locations which, <br /> due to surface topography/drainage or site activities, are anti- <br /> cipated to have a higher likelihood of being chemically impacted. <br /> These borings will be drilled to ground water, an estimated depth <br /> -of-j-. 5--1Q_ feet--below the ground surface, using the--hollow=stem <br /> agger _drilling_method. - ---eLMli ,_tw-4 surface_water_sample <br /> s__ <br /> will be collected, one from each of two drainage ditches located <br /> at the Site, for analysis. Two near-surface sediment samples <br /> will also be collected from the base of the drainage ditches to <br /> -2- <br />
