Laboratory Testing <br />As per the CQC/QA plan, EEC personnel, during the site visit on May 24, 2017, obtained a relatively <br />undisturbed sample of the previously placed and compacted shale/siltstone bedrock material by hand <br />driving a "Shelby -tube" device approximately 12 inches into the compacted zone. This was performed <br />to obtain a relative "in -tact sample" for hydraulic conductivity testing in general accordance with ASTM <br />D 5084 Specifications. The samples were obtained at the general location of EEC Field Density Test No. <br />3 (5-24-17). Laboratory testing performed on the retrieved hydraulic conductivity sample included a <br />remolded "Flex -Wall Permeameter" test in general accordance with ASTM Specification D 5084 <br />Method A; results are shown below and are also included on the attached summary sheet. <br />Hydraulic Conductivity Test Results <br />Hydraulic Conductivity Laboratory Testing - Soil Classification <br />Sa - In Situ Dry Final Moisture Final Dry Hydraulic <br />Moisture, % ensity, PCF Content, % Density, PCF Conductivity, cm/s <br />3 - (5-24-17) 15.0 111.2 19.5 110.3 4.75 x 10-7 <br />Based on the reported field density test results and the laboratory test results as presented herein, this <br />lift within this phase of the placed and compacted shale/siltstone bedrock material generally conforms <br />to the project specifications and the CQC/QA plan dated March 12, 2013. <br />Earth Engineering Consultants, LLC <br />ASCI — Turnpike Reservoir — Erie, Colorado <br />EEC Project No. 1174016 <br />June 7, 2417 <br />Page 3 <br />We appreciate the opportunity to work with you on this project.
