(GTI) <br /> proposes to submit one soil sample from each of the three lithologically distinct layers for <br /> geophysical analyses. The geophysical analyses will aid in calculating the mass of <br /> contamination remaining in the soil and move the project toward achieving a no further action <br /> required sanction. The soil samples have been previously collected and have been stored 'at <br /> 4 p p Y <br /> GTI. <br /> 1. Soil Sample Analyses <br /> • Submit one soil sample:from each of three lithologically distinct layers to Cooper <br /> Testing Laboratory: <br /> ❑ Moisture and Density'. <br /> ❑ Organic Content <br /> ❑ Total Porosity <br /> ❑ Permeability <br /> ED Hydraulic Conductivity <br /> 2. Risk Evaluation and Appendix B Site Closure <br /> • Prepare and submit reports and documentation required for requesting no further action. <br /> i <br /> Proposed Bidding of.Pro_ject <br /> 1. We have found that Cooper Testing Labs, Mountain View, CA to be both cost effective and <br /> competent in performing geophysical soil analyses., <br /> a <br /> A budget-spread sheet is attached and shows itemized cost for the tasks proposed. In an attempt <br /> to make this Pre-Approval flow smoothly, we have used the same unit costs for this work that <br /> have previously been approved by the USTCFP for other projects. <br /> I Geological Technics Inc. .accepts field support services and lab invoices and adds a 15% <br /> overhead fee. <br /> I <br />
