Underground Storage Tank (UST) Locating Services
Abandoned underground storage tanks (USTs) are one of the most overlooked risks on redevelopment and excavation sites. Old fuel tanks, oil tanks, and chemical storage tanks, some installed decades ago and long forgotten, can pose serious environmental, safety, and liability risks if they’re struck during construction or left undocumented during a property sale.
Venegroup ENG’s trained technicians use Ground Penetrating Radar to locate and map both active and abandoned USTs and associated piping, giving property owners, developers, and environmental consultants the information needed to plan safely around them or address them as part of remediation.
What UST locating identifies
- The presence and approximate location of tanks, whether documented or unknown
- Associated fill lines, vent pipes, and product lines connected to the tank
- Tank orientation and approximate depth to support excavation or removal planning
Venegroup ENG’s trained technicians use Ground Penetrating Radar to locate and map both active and abandoned USTs and associated piping, giving property owners, developers, and environmental consultants the information needed to plan safely around them or address them as part of remediation.
What UST locating identifies
- Before purchasing or redeveloping a former gas station, industrial site, or older commercial property
- As part of a Phase I or Phase II Environmental Site Assessment (see Environmental Due Diligence)
- Before any excavation on a site with an unknown or uncertain tank history
- To satisfy state or local requirements before tank closure or removal
Deliverables

Frequently Asked Questions
- Can you tell if a tank is still active or abandoned?
Our locating technology identifies the tank and its associated piping; determining active status typically requires additional investigation by an environmental professional, which we can coordinate around. - Do you handle tank removal? No, Venegroup ENG locates and maps tanks, removal and remediation are handled by licensed environmental contractors, who rely on our data to plan the work safely.
