Petroleum Storage Tank Compliance

Although the 1998 USEPA deadline for upgrading or removing federally regulated underground storage tanks (USTs) has passed, tank owners continue to call on Conrad Geoscience to remove and replace outdated tank systems.


Our tank services include:

  • Tank removal

  • Tank replacement

  • Soil testing and disposal

  • Non-invasive geophysical surveys

  • Construction management for larger scale tank upgrade projects


Our geoscientists also prepare tank closure site assessments required by regulatory agencies, and conduct spill investigations when needed.


Typical tank closure site assessments include:

  • Collection and analysis of soil and groundwater samples

  • Photo documentation of site conditions

  • Regulatory reporting

  • Conferral with regulatory officials


Conrad Geoscience scientists have been qualified as experts in cases where the timing, source or responsibility for a spill are in dispute.
