Underground Storage Tank Removals

Metal underground storage tanks have a limited lifespan. Due to underground conditions that contribute to corrosion, metal underground storage tanks all eventually leak. The smart play is to remove the tank before it leaks and becomes an expensive liability contaminating the soil and sometimes even the groundwater.

When to Remove an Underground Storage Tank

Underground storage tanks have limited life spans.  Over time underground storage tanks holding oil, gasoline, diesel, etc., begin to rust and corrode, ultimately leaking into the ground and posing a significant threat to the environment.  A leaking tank can seep under the foundation of a home or building, onto a neighbors property, or into the groundwater.  Being proactive and removing the tank before the end of it’s life span can result in a removal that costs significantly less than waiting until it’s too late.

When Do You Need To Replace An Aboveground Storage Tank?

Do you see corrosion on your tank’s bottom, seams, welds, or piping or seepage on the ground?  These are all indications that you should strongly consider having your tank removed. For any aboveground storage tank that is out of compliance, improperly abandoned, or suspected of leakage,  we have the expertise and experience to remove it quickly and efficiently, with minimal impact to your property and your business.

When do you need soil remediation?

When an underground storage tank is removed and it’s discovered it had been leaking or in some cases had been overfilled, soil remediation most likely will become necessary.  An underground storage tank leak can be caused by several factors, such as the age and thickness of the tank, the moisture content of the soil, etc. There are normally other telltale signs such as strong odor or visible staining of the soil

As an environmental consultant, solid contractors are so important to overall job success. Whether it be tank removal services, hotspot soil removal, test pitting, or waste hauling, Stewart Environmental Remediation is my number one choice by a longshot. Chris, Deb, and their staff make an excellent team and are always a pleasure to work with. Unlike some other contractors that require constant hand holding/follow up and hit you with change orders in the middle of the project, Stewart is always so well prepared for every job and are excellent communicators. They are experts at their craft. No matter how difficult of a job, they will always find a way to a successful end result while staying within budget every time. I look forward to working with them for many years to come. Highly recommended. Thank you Chris and Deb for all of your hard work on my projects!
