Precision Tank Testing
We currently offer computerized storage tank testing which is the latest
technology available in the industry. This advanced test system is
designed to give accurate on-site results in less than 90 minutes.
First Action uses tank testing methodology which meets or exceeds
all state and federal EPA requirements and our company is licensed
by the state to test regulated underground tanks.
Specifically, our tank testing involves a two part procedure.
The first part is the Precision Tank Test which checks the
integrity of the filled portion of the tank by measuring the
changes in the net buoyancy forces on an electronic probe. The
second part, the Ullage Test, checks the integrity of the empty
portion of the tank and the piping using acoustical profiling to
determine if there is a leak.
How it works
Filled portion test - evaluates the portion of the tank that
is filled with liquid.
- Our technician lowers an electronic probe and electronic
load cell into the tank through the fill pipe.
- The electronic probe is suspended inside the tank and hangs
from the load cell. The probe actually floats in the liquid fuel
inside the tank approximately 1'' from the tank bottom.
- The electronic probe and cell measure minute changes in mass
of the liquid fuel inside the tank. Measuring mass changes
eliminates the need to correct for the liquid fuel's temperature
expansion and contraction.
- Specifically, if water enters the tank, the electronic probe
rises. If liquid fuel leaks from the tank, the probe falls.
These changes in mass are instantly recorded in a unit called a
- The data logger readings are transferred to a computer,
which transforms the readings into a graphic illustration of the
integrity of the liquid fuel portion of the tank.
Empty portion test - evaluates the empty portion of the tank
- Our technician lowers a digital acoustical probe inside the
- The probe monitors the acoustical signals in the empty
portion of the tank and piping.
- Our computer converts these acoustical signals into a
graphic & acoustical profile of the integrity of the empty
portion the tank and associated piping.
First Action Testing
|Test results in 2 hours.|
|Test is not affected by high water tables and clay soil.|
|Test can distinguish between leaks in the piping and leaks
in the tank. This unique feature enables us to isolate oil
tank leaks and therefore, we can distinguish between major
repairs requiring tank closure and minor repairs such as
tightening a fitting or replacing a leaking vent/fill pipe.
Other companies offering test methods without this feature
usually recommend removing the entire tank from the ground when
all that was needed was a minor inexpensive piping repair.
Our data shows that 80-85% of tank tightness failures only
require minor repairs, thus, saving tank owners thousands of
dollars in unnecessary remediation costs. |
|No danger of damaging the tank.|
|Test is approved in all states by the Federal EPA.|
|Test distinguishes leaks in the empty portion (vent and
fill pipes) from leaks in the filled (wetted portion) of the
|Test is computerized for precise analysis of test
results. This eliminates operator error during data
In addition to tank testing, First Action offers underground
tank location services and soil testing. We will certify the
absence or existence of abandoned underground storage tanks on the
property using specially designed underground storage tank
detectors. We also have a reliable procedure for determining
whether the soil is free of contamination. We recommend our soil
testing procedure exclusively for inactive or abandoned
