Geophysical Investigations

.......

Enviroprobe’s geophysical technicians use a variety of geophysical equipment to map the subsurface in real-time.  This high resolution mapping is invaluable for locating utility lines and UST's when drilling or geoprobing in the area.  However, geophysics can be useful to answer a wide array of geotechnical questions.  The following is a list of other applications:

• Locate metallic and nonmetallic pipes and utility lines
• Locate and delineate under ground storage tanks (metallic and non-metallic)
• Landfill boundary mapping
• Delineate pits and trenches containing metallic and nonmetallic debris
• Delineate leach fields
• Delineate previously excavated and backfilled areas
• Map shallow ground water tables
• Map shallow soil stratigraphy
• Map shallow bedrock topography
• Map subsurface voids and cavities
