PORT OF EVERETT SECTION 01011 <br />NORTH MARINA REDEVELOPMENT SUMMARY OF WORK <br />SHALLOW SOIL VCP CLEANUP ACTION <br />analytical results indicate that contamination is lazgely limited to the upper 3 ft of soil, <br />and azsenic and cPAHs aze the primary constituents of concem. A few azeas of deeper <br />soil contamination are present and analytical results for groundwater samples collected <br />at these locations indicate groundwater has been impacted by contaminants in the soil. <br />Additional information is presented in the Cleanup Action Plan. <br />C. In general, Site geologic conditions encountered within the depth range of enviroi,:nental <br />explorations consisted primarily of a pavement section or a granular fill trat'ficking layer <br />overlying hydraulic fill. The hydraulic fill is typically a loose to medium dense, poorly <br />graded fine to course sand with silt or silty sand; this fill layer is about 20 fi thick <br />throughout most of the Site, but appears to thicken to 30 R or more towazd the westem <br />end. Organic material in the form of wood chips, bark, and related material was <br />encountered in thc hydraulic fill at many of the boring locations. Native marine <br />sediment consisting of soft to loose silt to silty sand dircctly underlies the hydraulic iiil. <br />Glacial soil, consisting of dense, granular soil of variable composition, underlies the <br />marine sediment unit. <br />D. The depth to �vater typically ranges from about 3 to 7.5 ft below ground surface (BGS). <br />"Che depth to water gencrally appears to be shallo�+�er toward the center of the Site and <br />deeper in the viciniry of the shoreline, which is consistent with groundwaler flow to�vard <br />marine surface water. It is in!ended that the shallow soil removal activiti�s be conducted <br />above th�e water s arface during dry site conditions, and that any stormwater within the <br />excavations be allowed to infiltratc into the hydraulic fill unit. <br />1.05 GENERAL SCOPE OF WORK <br />A.
