Description: Over 130 soil samples were collected from three soil borings in support of the VZFTS. The first boring was sampled just prior to the first injection test. The other two borings were sampled after completion of the injection tests. These soil samples were collected using a 7.6 cm (3 in) ID splitspoon sampler, with internal 15 cm (6 in.) long Lexan? liners. The samples ranged in depth from 4 to 17 m (13.5 to 56.5 ft), and were submitted to various laboratories for hydraulic property characterization and/or geochemical/tracer analyses. Preliminary results indicate that the major concentration front of the bromide tracer reached a relative depth of 5 m (below the injection point) 8 days after the final water injection and had migrated to a relative depth of about 7 m, 4 days later.
