A range of gauges with different scales will be <br /> available during the tests to allow measurement of a range of vacuum in the soil vapor. The <br /> extraction well vacuum will be monitored with a gauge connected to a manifold installed on the <br /> blower. <br /> wp-CS-SVE-May09-09366.dmdeh 8 <br />
