Soil sampling was complemented by surface geophysical measurements. Two methods were chosen on site because of their ability to infer physical properties correlated with the lithology: electrical resistivity tomography ERT and seismic refraction tomography. In total, nine parallel ERT lines were acquired along the east-west direction and 10 parallel. in this compendium include Sampling Equipment Decontamination, Soil Sampling, Soil Gas Sampling, and General Surface Geophysics. The compendium describes procedures for collecting representative soil samples and provides a quick means of waste site evaluation. It also addresses the general procedures used to acquire surface geophysical data. For more information on Soil Sampling and Surface Geophysics procedures, refer to the Compendium of ERT Soil Sampling and Surface Geophysics Procedures, OSWER directive 9360.4-02, EPA/540/P-91/006. Topics covered in this compendium include Sampling Equipment Decontamination, Soil Sampling, Soil Gas Sampling, and General Surface Geophysics. TITLE: SOIL SAMPLING CATEGORY: ENV 3.13 REVISED: August 1997 5. Potential Problems Potential problems with soil sampling include cross-contamination of samples and im proper sample collection. Cross-contamination problems can be eliminated or minimized through the use of dedicated sampling equipment and bottles.

Electrical Resistivity Tomography ERT is an advanced geophysics method used to determine the subsurface’s resistivity distribution by making measurements on the ground surface. ERT data are rapidly collected with an automated multi-electrode resistivity meter. ERT profiles consist of a modeled cross-sectional 2-D plot of resistivity Ω·m versus depth. EPA. 1991.

Near surface geophysical methods are commonly employed to map areas of contamination e.g., electromagnetic EM and ERT surveys to map saline plumes, detect buried utilities or tanks e.g., EM and GPR or detect tunnels or other voids.
SOIL GAS SAMPLING surface of chemically active soil particles, such as clays, thus reducing the concentration in the soil interstitial spaces. Similarly, some organic compounds can be dissolved in the soil water or associated with soil organic components i.e., humic acids.
