Case Studies


Underground Storage Tanks

Real estate transactions regularly create the need for an environmental site assessment. Confirming the presence or absence of underground storage tanks (USTs) can be a critical factor in contract closing. GPR reflection mapping surveys are commonly used to identify the presence of USTs. The example presented shows five storage tanks plus related pipes discovered at the site of a gasoline station.

Powerful yet simple data collection

Adjust data collection parameters and easily view data in the field with the high resolution, sunlight visible, touchscreen digital video logger (DVL).
DVL 500 Noggin

Rugged by design Noggins are used in a wide range of environments, temperatures, and weather conditions.
Ultra-wide band (UWB) GPR antennas Ground-coupled for maximum signal penetration and data quality.
Digital Video Logger High resolution, sunlight visible, resistive touch screen with Wi-Fi and USB data transfer.
Flexible data collection Change GPR parameters to optimize the survey. Adjust depth, step size, stacking, time window, grid size, triggering and more.

Mini reports and Noggin Data

Wi-Fi mini-reports Email a report of line, depth slice or map view data to your customers or colleagues.
Depth slicing Collect grids of data and view depth slices right in the field.
Map view Using external GPS, display a plan map view of survey path, grids, field interpretations and flags.
Field interpretations Add color-coded interpretations and field flags with the touch of a finger.
Optional GPS Integrated GPS for post-processing and export to Google EarthTM, CAD drawings & GIS databases.

The data collection software on the DVL 500 Noggins have default settings to get to work quickly; for line surveys just set the desired depth and start collecting.
For grid collection, the GPR operator sets the grid size and line spacing. The screen prompts the user to collect each line until the grid is complete. It is easy to work around obstructions, skip lines or recollect lines if required.
Once the grid is finished (or any time after at least 3 lines have been collected), the grid data can be processed into depth slices (right in the field!).

For users involved in unusual projects, Noggins also have custom settings to collect data with extreme values:

• Depths to 200 meters (320 m in ice)
• Triggering options include Odometer, Button and Free-Run modes
• Free Run in Time or Free-Run with Speed to collect data on water, snow or ice
• Grids up to 250 x 250m in size
• Zig-zag grid collection pattern
• Step Sizes from 5 millimeters to 5 meters

Create impressive deliverables easily with EKKO_Project software.

After data collection is finished, transfer the data to your computer and organize, edit, process and plot your GPR data with EKKO_Project. See your data in seconds – spend your time understanding the data, not importing and integrating ancillary information.
EKKO_Project’s reporting capability outputs interpretations and other information into PDF, spreadsheet (csv), Google Earth (kmz) and CAD (dxf) files.
Noggin systems provide valuable insights in countless subsurface applications. As your GPR knowledge and expertise grow, use your Noggin system to expand your business into new markets. Easily add another sensor, a new configuration or accessories to your existing Noggin system and your subsurface investigation opportunities are limitless.
