Fourth Street, Suite 200 Winston-Salem, NC 27101 Attention: Mr. Michael Kelly Subject: Infiltration Test Results Proposed Walgreens Store Morehead City, North Carolina Job No. R2106; Report No. 122584 Dear Mr..Kelly, Pursuant to the request of Mr. Don Gibbs of Greenhorne and O'Mara, a representative of QORE was at the subject project site on December 2, 2005 to perform a double -ring infiltration test on the in -situ soils. The test was performed at a depth of about two feet below the existing grade at the location shown on the attached Test Location Plan. A hand auger boring was completed next to the infiltration test location to explore the subsurface soil and groundwater conditions. The Nand Auger Boring Record and the results of the infiltration test are attached. In summary, the subsurface soils consisted of slightly silty Sand that extended to the 4-foot depth explored. Groundwater was measured at a depth of about 3.8 feet below the ground surface at completion. The test location was pre-soaked with a 10-gallon quantity of water and then 4 infiltration test trials were run. Based on the results of these tests, the infiltration rate of the in -situ soils was assessed to be about 30 to 35 inches per hour. Due to the rapid infiltration of water, the standard constant head test method per ASTM D-3385 was modified and performed as a failing head test; where as the elapsed time was recorded for 2000 ml of water to infiltrate the ground within the inner -ring and on this basis, the infiltration rate was calculated. We appreciate the opportunity to be of continued services to you. Should questions arise, please contact us at your convenience. Respectfully submitted, QORE, Inc. Thomas B. Baird, P.E. David T.
