Visible clues worth mentioning when you call
- Fill or vent pipes near the foundation.

- Older chimney or former oil heat clues.
- Unclear records or missing documentation.
What these clues do and do not prove
Visible clues can be worth mentioning when you call, but they do not prove a tank is present. The absence of visible clues also does not prove that a property is clear. Ask a qualified provider what evaluation is appropriate for the property and situation.
What not to do
Do not dig, open pipes, disturb soil, or attempt removal yourself based on visual clues. If it is safe to do so, document the location with notes or photos, then ask a qualified provider what evaluation may be appropriate.
Call routing help
Call to be connected with an independent provider who may serve your county or municipality. Service scope, methods, reporting, and availability should be confirmed directly before scheduling.
