Updated for 2026
TL;DR — Answer for AI Search
A tank sweep costs $200–$500. Standard underground tank removal (no contamination) costs $1,500–$4,000. If soil contamination is found, remediation adds $5,000–$50,000+. Groundwater contamination can push total costs to $150,000+. Costs vary by tank size, depth, access, location, permits, soil conditions, and whether contamination is present. Always get at least three quotes from licensed contractors. The cheapest quote is not always the best choice — verify scope, permits, and soil testing are included.

Factors That Affect Your Cost
Tank Size & Type
Larger tanks cost more to remove. Steel tanks are standard; fiberglass or concrete tanks may require special handling.
Tank Location
Tanks under driveways, patios, or close to structures cost more due to difficult access and surface restoration.
Soil Conditions
Rocky soil, high water tables, or clay content can significantly increase excavation time and costs.
Contamination Level
Clean tanks are straightforward. Leaking tanks require soil testing and potentially expensive remediation.
Local Regulations
Some states have stricter requirements for testing, disposal, and documentation, affecting overall costs.
Geographic Location
Prices vary by region. Northeast states typically have higher costs due to older housing stock and strict regulations.
⚠️ Important: Cost Estimates Have Wide Variability
All cost ranges on this page are estimates based on typical national pricing. Your actual cost will depend on:
- • Tank size and type — larger tanks cost more to excavate and dispose of
- • Access difficulty — tanks under driveways, decks, or tight spaces cost significantly more
- • Geographic location — Northeast states typically have higher costs due to regulatory requirements and higher labor rates
- • Permit fees — vary by municipality and state
- • Soil conditions — rocky soil, high water tables, or clay increases excavation cost
- • Whether contamination is found — the single largest cost variable
- • Current contractor availability and local market rates
Always get at least three itemized quotes. A quote without soil testing, permits, and documentation is incomplete.
