Screen Samples

 

500 MHz
500 MHz Screen Sample 500 MHz Data depicting buried drums on an environmental cleanup site. Overall depth 8.4 ft. (2.6 m)
500 MHz Screen Sample 500 MHz

From the surface the following are recognizable in the data:

  • Multiple layers of asphalt over a gravel layer with a small metal conduit in the gravel layer
  • Two large pipes side by side
  • Overall depth 8.4 ft. (2.6 m)
500 MHz Screen Sample 500MHz

Data depicting a fuel tank and pipes buried near a residential building. Disturbed soil from an excavation 35 years prior is obvious when compared to surrounding material. Overall depth 11 ft. (3.3 m)
500 MHz Screen Sample 500 MHz A UST approximately 4 ft. deep with pipe just above and a second pipe near surface. Overall depth 10 ft. (3 m)
500 MHz Screen Sample 500 MHz Granite foundation of a colonial building from an archaeological site is shown in this data. Overall depth 8.4 ft. (2.6 m)
500 MHz Screen Sample 500 MHz A number of large rocks are immediately discernible in this data sample. Overall depth 14.6 ft. (4.4 m)
     
250 MHz
250 MHz Screen Sample 250 MHz

Changes in material are obvious near the surface. At center, in this data sample approximately 8 ft. (2.4 m) from the surface, the water table and associated soil change from lean clay to silty clay is easily determined as a series of bands.
