One-liter Tedlar bag<br />Date Taken: 2/3/2003<br />Category: <br />Latitude: <br />Longitude: <br />Tags:
Active soil vapor sampling from temporary sample point. The cylindrical object in the left center of the photograph is a portable vacuum pump. An air sample is collected by pumping air through Teflon tubing and into a Tedlar bag.<br />Date Taken: 2/3/2003<br />Category: <br />Latitude: <br />Longitude: <br />Tags:
Split active soil vapor sample configuration, showing one-liter Tedlar bags and open vacuum box. A constant-flow pump, which is used to create a vacuum when the box is closed, is shown at the lower left.<br />Date Taken: 9/15/2003<br />Category: <br />Latitude: <br />Longitude: <br />Tags:
Groundwater Sampling Configuration, Low-Flow Sampling Method. This configuration and sampling method was used in September, 2003, as part of the PERC investigation.<br />Date Taken: 9/15/2003<br />Category: <br />Latitude: <br />Longitude: <br />Tags:
Coring device used to drill through concrete basement slabs<br />Date Taken: 7/22/2003<br />Category: <br />Latitude: <br />Longitude: <br />Tags:
A small-diamter driven well and open protective steel casing. Six small-diameter wells were installed during July and August, 2003, as part of the PERC investigation. The diameter of the steel cap is approximately six inches.<br />Date Taken: 9/11/2003<br />Category: <br />Latitude: <br />Longitude: <br />Tags:
