Corrosion Testing

ATS can predict your tanks reliability

Our comprehensive analysis will determine whether an underground tank is at high risk for catastrophic failure in the near future.

Corrosion Testing

Corrosion accounts for 90% of reported tank failures. Photo A depicts a corroding leaking tank that was removed from the ground. Photo B has been magnified 10x to highlight some of the corrosion damage.

Corrosion Evaluation Services

  • ATS is certified to conduct both corrosion evaluations and soil testing
  • Only a few elite companies in the northeast region are trained and certified to offer both services.

    An ideal inspection would include both tank testing and corrosive evaluation. The corrosive evaluation would add an extra layer of security by predicting whether the tank is at high risk for catastrophic failure in the near future.

  • Easy & Affordable
  • A basic corrosion analysis can be performed in conjunction with any tank or soil test for a nominal fee. Each corrosion evaluation will include a separate written report describing the corrosive state of the tank.

S.T.E.P.S. Soil Testing

  • ATS is one of a select few companies certified to perform S.T.E.P.S. testing.
  • Our soil testing personnel have undergone extensive training and obtained certifications by International Lubrication & Fuel Consultants (ILFC) to perform this comprehensive evaluation. ILFC developed the S.T.E.P.S. evaluation primarily for underground primarily for underground tanks under 1,000 gallons.

  • S.T.E.P.S. identifies oil in the ground & predicts the tank’s viability.
  • This testing process will detect the presence of petroleum product in the ground, identify the corrosion rate of buried steel tanks and determine the presence of other factors that accelerate corrosion.

    These factors include the presence of sulfide reducing bacteria, extent of acidity or alkalinity of the soil and level of dissolved salts which may impact the tank’s corrosion rate.

  • S.T.E.P.S. soil samples are laboratory analyzed.
  • After our environmental technicians extract soil samples from the area surrounding the underground tank, the samples are transported to ILFC for analysis. ILFC issues a comprehensive report based on their laboratory findings and our field corrosion evaluation.

Corrosion Testing FAQs

  • Why do buried tanks corrode?
  • Corrosion is caused by the inherent tendency of iron based metals in underground storage systems to revert to a stable form (known as rust). When steel turns to rust it is an electrochemical process which is dependant on variables that are present in the soil such as soil moisture, pH acidity, backfill material, physical location and any scratching or damage occurring during the tank’s installation.

  • Can S.T.E.P.S. testing be performed in conjunction with tank testing?
  • Our comprehensive inspection services include both tank testing and S.T.E.P.S. testing as part of one evalation. Click here to find out more about are tank testing options.
