The lifespan of a buried steel heating oil tank can vary widely depending on the soil conditions and surrounding environment.

tank testingHome-buyers intending to remain oil heat customers should protect their investment by evaluating the tank and soil during the inspection period.

You may also want to consider insuring the tank.


1. Tank Testing & Soil Evaluation (All-inclusive)

  • Uses a sophisticated computer analysis program to evaluate the tank and piping.
  • Will identify problems with the integrity of the tank and piping.
  • Includes an on-site laboratory analysis to determine if there is petroleum in the soil.
  • You will receive a written pass/fail report.

Tank test failures can often be repaired. In these cases, we will do our best to identify the problem area.

Cost: This is our most economical inspection.
Reports: Available 24 hours after the inspection.
Test Results: Available on-site.

2. Tank Testing & Soil Analysis (Most Comprehensive)

  • Combines our tank testing services with corrosion analysis of the underground tank.
  • Corrosion evaluation predicts whether the tank is at high risk for catastrophic failure in the near future.
  • Includes soil analysis, a tank test report, the official laboratory report, and our analysis interpreting the findings of the inspection for you.

Cost: Same as the above inspection with an additional fee to evaluate four samples. Includes state certified laboratory samples.
Reports: 3-5 days. Expedited laboratory reports are available for an extra fee.
Test Results: Tank results are available on-site. Soil results are available in 3-5 days.

Caution! Beware of companies claiming to perform a complete laboratory analysis overnight or on-site!

The state approved soil testing method is complicated and takes time. Ask the company for the specific compounds tests. Check with our soil testing experts to make sure the company is performing an approved test!

Will tank testing damage my tank?
No! ATS uses state of the art technology that will not harm the underground tank.

Years ago, many companies used air pressure testing as a means to evaluate underground tank systems. This type of testing could potentially damage the tank and associated piping. Today, strict pressure testing is not an approved test method in most states.

My oil company performed a water test and their representative concluded the tank does not have a problem. Do I need to test the tank using another method?
Absolutely yes!

Underground tanks may leak without ever taking on water. It is possible that a tank located in a dry area may have holes and water may never enter the tank because the water table is far deeper than the buried tank.

Also, finding water in a tank may not indicate a tank failure. Often, water can enter the tank through small leaks in the vent pipe or fill pipe. Vent or fill pipe problems are easily repaired.

Advantages of using ATS for tank testing:

  • Distinguish leaks in the tank from leaks in vent or fill pipes.
  • Why is this important? A pipe leak that is mistaken for a tank leak may result in removing an entire tank when only a minor, inexpensive piping repair is required. Do not waste money!

  • On-site results!
  • Our sophisticated testing technology can often evaluate the underground tank and system in under 90 minutes.

  • The best technology in the industry.
  • We use the Mesa 2D Test System which provides digital testing that is safe, fast, reliable and affordable!

State & Federal Certifications:
All of our testing processes are federal and state approved testing methods for evaluating underground tanks. In addition, ATS holds current licenses in several cities, counties, and states.
