Put the the protective cap and flush mount cover <br /> Nylaflow tubing as close to the VAPOR until the next event. If the sampling is <br /> PIN® as possible to minimize contact complete, extract the VAPOR PIN®. <br /> between soil gas and TygonTM tubing. <br /> Extraction Procedure: <br /> 1) Remove the protective cap, and thread <br /> the installation/extraction tool onto the <br /> barrel of the VAPOR PIN® (Figure 7). <br /> Turn the tool clockwise continuously, <br /> don't stop turning, the VAPOR PIN® will <br /> �J <br /> feed into the bottom of the <br /> installation/extraction tool and will <br /> Figure 5.VAPOR PIN® sample connection extract from the hole like a wine cork, DO <br /> NOT PULL. <br /> 10) Conduct leak tests in accordance with <br /> applicable guidance. if the method of 2) Fill the void with hydraulic cement and <br /> leak testing is not specified, an alternative smooth with a trowel or putty knife. <br /> can be the use of a water dam and <br /> vacuum pump, as described in SOP Leak <br /> Testing the VAPOR PIN® via Mechanical <br /> Means (Figure 6). For flush-mount <br /> installations, distilled water can be <br /> poured directly into the 1 1/2 inch <br /> (38mm) hole. 4L <br /> Y <br /> Figure 7.
