Find your situation
Equipment shut down? A notice or deadline to address? An alarm you cannot explain? Start with the problem you need to resolve.
Equipment Out Of Service
The state shut down a tank or dispenser. Find out what needs to be checked and what records are needed for the next review.
Identify Next StepsTesting Deadline Approaching
A deadline or compliance notice needs attention, or you do not know what is due. Start with the site records and last test dates.
Determine What Testing Is DueAlarm, Loss, Or Suspected Release
The ATG is alarming, inventory does not reconcile, or you suspect a leak. Work through what happened and what needs investigating.
Discuss The InvestigationNew Site Or Acquisition
You are buying, opening, or taking over a site. Review its equipment, testing history, and unresolved requirements.

Community SupportIndependent testing. Documented results.
Direct technical contact, equipment-specific procedures and reports your project team can use.
Testing matched to your equipment
We review the system configuration, prior reports and inspection notice before confirming the tests, access and documentation needed.
Technical expertise for your operations
USTEX applies equipment-specific training and technical expertise to evaluate tank systems and provide clear, actionable documentation for facility operators, engineers, and project teams.
Direct technical communication
Facility and project contacts have direct access to the technical specialist performing the work, from scheduling through the completed report.
Methods, measurements and findings
Reports identify the equipment, procedure and results, with relevant observations and limitations for your operator, engineer or reviewing agency.
USTEX provides specialist diagnostics alongside your existing project team. The findings give operators, engineers and service contractors a documented basis for the next step. How the partnership works.
Tank and fuel-system testing services
Tank and fuel-system diagnostics for routine testing, inspection findings and equipment investigations. USTEX reviews equipment details and project purpose to confirm the appropriate scope. Wisconsin UST testing and testing inquiries are available here.
UST and tank tightness testing
USTEX evaluates underground storage tank integrity and release detection equipment for periodic compliance testing, inspection findings, and suspected leaks.
Aboveground storage tank testing
USTEX provides diagnostic testing for aboveground tanks, connected fuel piping, containment, and supply systems serving commercial and public facilities.
Line tightness and leak detector testing
Product-line tightness and leak detector functionality are separate evaluations of the fuel delivery system.

Storage tank testing questions
How often do underground tanks need testing?
- Periodic testing is required for each site. USTEX reviews the facility testing history and upcoming obligations to establish the next testing cycle.
- Tank tightness tests, line leak detector checks, containment tests and ATG operability checks have different purposes and schedules.
- USTEX reviews available equipment details, prior reports and inspection notices to confirm the next testing scope. Testing inquiries are reviewed individually.
How does USTEX work with our engineer or service contractor?
- USTEX provides a defined diagnostic testing scope, objective measurements and documented results.
- Your engineer, consultant or service contractor can use the report to evaluate the tested equipment and plan follow-up work.
- We coordinate access, testing and the report handoff with the project contacts you identify.
How fast can you get to a red-tagged site?
- USTEX reviews the site location and inspection notice to assess the urgency and required testing. Phone: (414) 301-3645.
- Red-tagged facilities and leak investigations are treated with urgency, with dispatch within 24 hours.
- The reviewing agency determines what is required to release the tag. Testing results support that review.
What does a multi-site program look like?
- We agree on the facilities, equipment, due dates and reporting format before scheduling.
- Sites can be coordinated through one point of contact, with reports identified by facility and equipment.
- Testing scope, technician authorization and applicable requirements are confirmed for each jurisdiction.
