These images show MASW results and the variability of cemented sand above bedrock. This information is valuable in determining the optimal placement of extraction wells to remove groundwater contamination. Image by Jeremy Strohmeyer.

The MASW method provides a direct indication of soil stiffness and is well suited to identifying soft soil zones, cemented sands, and depth to bedrock. These profiles show the variability of a cemented sand layer within sediments overlying bedrock. These results were used to determine the optimal placement of groundwater extraction wells to remove contamination.
