Oil-Contaminated Soil Testing & Remediation

When a buried tank leaks, the problem moves from the tank to the soil — and left alone it migrates toward groundwater and foundations. Testing tells you the extent; remediation cleans it up.

Oil-Contaminated Soil Testing & Remediation — the problem we remediate

The problem

Test the Extent, Then Clean It Up

Soil sampling establishes how far the contamination reached; remediation removes or treats the affected soil. Scoping it accurately keeps the cleanup no larger than it needs to be.

The approach

Document It Properly

Oil releases often come with reporting and closure requirements. We handle the assessment and cleanup with documentation that satisfies a buyer, an insurer, or a regulator.

A buried oil tank fails from the outside in. By the time it’s noticed, the leak is usually already in the soil — which is why removal and soil checks go together.

How it works

A Documented Process, First Look to Verified Result.

  1. 01 Assessment & Locate We find the tank, check access, and pull the required permits.
  2. 02 Pump & Clean Residual oil and sludge are removed and disposed of properly.
  3. 03 Excavate & Remove The tank is excavated or cut out and hauled off as regulated waste.
  4. 04 Soil Testing Surrounding soil is sampled to confirm there’s no contamination.
  5. 05 Backfill & Documentation The site is restored and you receive full closure paperwork.

Common questions

Before You Call, the Honest Answers.

How do I know if my tank leaked into the soil?

Soil sampling around the tank is the way to know — visible staining or odor at removal is a flag, but testing confirms the extent. We assess it at removal.

How much soil has to be removed?

Only as much as testing shows is affected. Accurate assessment is what keeps the remediation proportionate rather than over-scoped.

Is there paperwork involved?

Often yes — releases can trigger reporting and closure requirements. We handle the documentation so the site has a clean, defensible record.
