Underground Storage Tank Locating,
Soil Sampling, Oil Tank Removal and Decommissioning Services

Underground Storage Tank Locating Service

Underground Storage Tank locating services are conducted with the utilization of a Fisher model TW6 locator. This method is a non-evasive method which detects large metallic objects beneath the earth’s surface. We will be able to find your underground oil tank.

Underground Storage Tank Soil Sampling

Underground storage tank soil sampling is conducted using the Geo-probe method. This method enables us to collect a soil sample along the sides of the tank while the tank remains in place.

Residential and commercial underground storage tanks have historically have been the source of many environmental problems as their life expectancy is approximately 15 years.  Life expectancy depends greatly on the tanks location. A leaking underground storage tank may potentially contaminate groundwater and impact well water. Often a leaking underground storage tank goes undetected until the tank is removed from the ground.

Fuel Storage Tanks

Envirotech of Fairfield County Inc. removes and replaces Underground Fuel Storage Tanks (UST) and Above Ground Storage Tanks (AST) as well as the remediation as necessary. They understand that to remove a fuel tank is more than just an isolated issue. They are professionally trained and certified to check your tank for heating oil leaks, improper workmanship and defective materials. They can use a tool known as a geoprobe to test the soil around the tank to test for leaching of petroleum products into the soil. EnviroTech uses metal detectors to determine the presence of an underground tank.

Leaking underground storage tanks can cause indoor air pollution and can potentially contaminate drinking water and soils. Often a leaking UST (Underground Fuel Storage Tanks) will not be detected unless the tank is removed from the ground.

Periodic checks of your tank can help to save you money. The longer that a leaky tank seeps petroleum into the soil and is dispersed to the surrounding area, the more the clean up costs will be. Save yourself grief by performing visual checks of your oil tank and all it’s connections on a regular basis.Oil tank testing for home heating oil tanks can detect fuel oil leaks and save you a great deal of money. You can use our geo-probe services to help you locate your tanks. Another problem might be an abandoned tank on your property. Many people have had a home oil tank or a leaking oil tank on their property and never knew about it.
