VLX!—® Technical Memorandum <br /> Delta Water Supply Project <br /> Field Resistivity Testing Procedure for Encroachment Permit <br /> Prepared by: Keith A. Packard, P.E., V&A <br /> Date: January 10, 2008 <br /> File: 07-0281 <br /> V&A Consulting Engineers is a subconsultant to CDM to provide soil corrosivity testing and analysis of the <br /> pipeline right of way for the Delta Water Supply Project. Field testing for soil corrosivity evaluation will include <br /> in-situ resistivity testing conducted at 1,000-foot intervals on the pipeline alignment. Proposed test locations are <br /> indicated on Sheet CP1. <br /> Resistivity testing will be performed on the unpaved shoulder of West Eight Mile Road between Davis Road and <br /> Empire Tract. The exact location of the testing will be determined by the technician in the field based on space <br /> available to pull off of the road to either the north or south shoulder. <br /> The in-situ resistivity testing is an electrical test method and does not involve boring, drilling or excavation to <br /> perform the test. The soil resistivity measurements will be conducted by the Wenner 4-Electrode Method, <br /> ASTM G57, using a Soil Resistance Meter (Model 400, manufactured by Nilsson Electrical Laboratory, Inc.). <br /> The Wenner method involves the use of four metal electrodes, 'h-inch diameter steel pins, driven 4 to 6 inches <br /> into the ground along a straight line, equidistant from each other, as shown in Figure 1. <br /> Soil Resistance <br /> Meter <br /> i� <br /> P1 O P2 <br /> C1 C2 <br /> A A A <br /> Equally Spaced Electrodes in Straight <br /> Line <br /> Figure 1 - Soil Resistivity Measurement <br /> Encroachment Permit Text.doc Page 1 <br />
