|---|---|---|
| Tank sweep / locate | $150 – $500 | Buy this first when the tank's existence is the question |
| Soil testing | $300 – $1,000 | The only thing that confirms or clears a leak |
| Underground removal, clean soil | $1,500 – $3,500 | Up to ~$5,000 with difficult access |
| Aboveground / basement removal | $500 – $1,500 | Cheapest fix for most insurance flags |
| Closure in place (abandonment) | $1,000 – $2,500 | Saves ~$500–$1,500 now; renegotiated at every future sale |

| Remediation, confirmed leak | $3,000 – $15,000 | Most homes $8,000 – $10,000; severe cases exceed $100,000 |
Five states, one table
| State | Typical range | What moves it |
|---|---|---|
| New Jersey | $1,500 – $3,500 | Buyer-sweep culture; rocky north-west counties dig harder |
| New York | $1,700 – $4,500 | Long Island and Westchester labor and disposal at the top |
| Connecticut | $1,500 – $3,800 | Insurance pressure statewide; older shoreline stock |
| Massachusetts | $1,800 – $4,200 | Fire-department permitting; island logistics cost extra |
| Pennsylvania | $1,200 – $3,200 | Cheapest labor of the five; long disposal hauls rural |
Three jobs, three invoices
Illustrative — built from the ranges above, not real invoices.
| Line item | Amount |
|---|---|
| Removal, disposal, backfill | $1,900 |
| Municipal permit | $150 |
| Post-excavation soil samples | $400 |
| All-in | ≈ $2,450 |
| Line item | Amount |
|---|---|
| Removal, permit, sampling (as above) | $2,450 |
| Excavation + disposal of impacted soil | $6,800 |
| Confirmatory samples + closure documentation | $1,500 |
| All-in | ≈ $10,750 |
| Line item | Amount |
|---|---|
| Assessment, delineation, monitoring wells | five figures |
| Excavation, treatment, long-tail monitoring | variable |
| Documented severe cases | $100,000+ |
The distance between Job 1 and Job 2 is one soil sample nobody ran earlier. That is the entire economic argument for acting while the tank is still a $2,450 problem — the leak-risk tool scores where yours likely sits.
What moves the number

| High groundwater (coastal, low-lying) | +10 – 25% |
| Residual oil, sludge, sand or foam fill | +$250 – $1,200 |
| 1,500+ gal tank | +10 – 20% |
| Landscaping / hardscape restoration | variable |
The reality checks
- A firm remediation price quoted before soil data exists is a red flag — nobody can price what hasn't been measured.
- "Free, state-funded removal" pitches don't survive contact with program status pages. Check what relief actually exists in your state before believing one.
- The cheapest bid usually omits line items that return as change orders. An itemized scope — permit, disposal documentation, sampling, restoration — is worth more than a low number.
- Ranges here are informational. The only real number comes from a licensed contractor standing on your property.
