The first step in cleaning up a tank leak is to define the extent of the leak.  Unfortunately you cannot accurately guess how bad a tank leak is from looking at the ground.   ![oil tank remediation-3](https://www.currenenvironmental.com/hs-fs/hubfs/oil%20tank%20remediation-3.jpg?width=1280&name=oil%20tank%20remediation-3.jpg) Like determining a cancer diagnosis with biopsy sample, underground soil testing needs to be performed to determine how deep and how far the oil has spread. This diagnosis of the area of oil contamination is called delineation.  You determine the extent of an oil tank leak by performing test borings both in and surrounding a tank leak.  The borings are drilled into the ground to both physically evaluate soils for the presence of petroleum as well as to test soils for oil concentrations (yes there are legal amount of oil that can remain in the ground).  The number of test borings required to define the extent of contamination is based on how far the oil has spread.  Simple put the bigger the problem the greater the number of time and borings, the smaller the problem lesser the time and number of borings. [My Oil Tank Leaked](https://www.currenenvironmental.com/oil-tank-leaks-leaking-oil-tanks-what-you-need-to-know)   The simple science of delineating an Underground Storage Tank (UST) Leak is essential in cleaning up a tank leak for two important reasons:   ![Leaking UST Investigation_3](https://www.currenenvironmental.com/hs-fs/hubfs/Leaking%20UST%20Investigation_3.jpg?width=800&name=Leaking%20UST%20Investigation_3.jpg) 1. The cost to cleanup an oil tank leak is based on how much soil and groundwater has been contaminated.  Guessing the number of tons of impacted soil is just  a guess. 2. The foundation of any remediation project is knowing where and how much to dig.  Knowing the extent of the plume (area) allows you to to efficiently cleanup an oil tank leak by knowing how much soil will need to be addressed.   [![Click me](https://no-cache.hubspot.com/cta/default/28573/b533989c-3842-43e9-b061-bbc45009a23b.png)](https://cta-redirect.hubspot.com/cta/redirect/28573/b533989c-3842-43e9-b061-bbc45009a23b)   Once the area (length and width) of the contamination is determined an estimate can be developed to remediate the problem.  Knowing where the extent of the contamination is below ground can assure you that the proper personnel and right sized equipment is brought to your site to remediate the contamination.   # **The Curren Advantage** 1.
