Ground Penetrating Radar Investigation To Delineate Former UST Excavation Area

An out-of-state environmental consulting company contacted Enviroprobe for a project in New Jersey. The property currently was a hotel. Records show that the property was once a gas station with underground storage tanks. The old site plan showed the approximate location of a former UST which supposedly had been removed. However, the plan was not scaled and out of proportion, creating difficulty for selecting soil boring locations. Enviroprobe performed the ground penetrating radar investigation and delineated the former UST excavation area. The results were provided in real time and it’s immediately followed by drilling which was also performed by Enviroprobe. All activities were conducted

Marine ERI For Sub-Bottom Layer Thickness Estimation

In the Fall of 2015, a geophysical survey crew from Enviroprobe Service Inc. was mobilized to Upstate New York to perform a geophysical investigation using the marine electrical resistivity imaging (ERI) method. The purpose of the investigation was to investigate the sub-bottom materials in a river, specifically the thickness of the soft layer at the river bottom underlying by hard glacial till or bedrock. This soft layer was mostly clay or silt. The target survey area was about 5 miles long. The area had been investigated using other geophysical methods including GPR and sub-bottom profiling. These two methods were not effective due to the site conditions. Electrically conductive sub-bottom

Find The Casing Bottom Of A Well

Although a video camera can usually be sufficiently enough to find the bottom of the casing for a well, sometimes the video camera doesn't work due to corrosion and deposits on the walls of the hole. In such cases, geophysical logging tools such as the caliper could be very useful. Enviroprobe conducted an investigation in a well using both video camera and geophysical borehole logging. The casing bottom was not clearly visible in the video but its depth can be discerned from the caliper log as shown in the image.
