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.   ![large oil plume](https://www.currenenvironmental.com/hs-fs/hubfs/large%20oil%20plume.jpg?width=2345&name=large%20oil%20plume.jpg) **The simple science of delineating an Underground Storage Tank (UST) Leak is essential in cleaning up a tank leak for two important reasons:** 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 guessing. ![oil tank leaking nj de pa](https://www.currenenvironmental.com/hs-fs/hubfs/oil%20tank%20leaking-5.jpg?width=2266&name=oil%20tank%20leaking-5.jpg) ***The tank that leaked in this photo leaked for a long time and the formation was very sandy with a high groundwater table allowing the oil to pancake or spread.***   The foundation of any remediation project is knowing where and how much to dig.  Knowing the extent of the plume allows you to efficiently cleanup an oil tank leak by knowing how much soil will need to be addressed. ![leaking tank investigation](https://www.currenenvironmental.com/hs-fs/hubfs/2018.04.23%2010.09.59.133.jpg?width=3024&name=2018.04.23%2010.09.59.133.jpg) ***The tank leak in this photo was a minor leak soils were tight and cleanup was finished in one day for slightly less that $8,000.00.   A lot of money, but not as bad as the prior tank photo.    Each tank leak is unique.***   Delineation (obtaining soil samples from the area of the leak to determine the size of the leak) is accomplished by using ATV mounted drilling equipment.  The delineation acquires soil sampling to determine the horizontal and vertical size of the area of contamination. ![Soil borings with geoprobe ATV for tank leak NJ DE PA](https://www.currenenvironmental.com/hs-fs/file-2150633276-jpg/images/P1080680-resized-600.jpg?width=597&height=448&name=P1080680-resized-600.jpg) **Geoprobe ATV Drilling Unit, this compact drilling unit is 41" wide allowing access to hard to reach locations.  With a drilling depth of 25'+ the unit can tackle jobs big and small. ** [![Questions About Remediation Click Here](https://d1n2i0nchws850.cloudfront.net/portals/28573/b37bce28-92c9-4812-b529-8b94a54c87f1-1329938516989/questions-about-remediation-click-here.png?v=1329938517.24) ](http://cta-service-cms2.hubspot.com/cs/c/?&cta_guid=b37bce28-92c9-4812-b529-8b94a54c87f1&placement_guid=b533989c-3842-43e9-b061-bbc45009a23b&portal_id=28573&redirect_url=rXhFy8QE40YImoDtv2X5RNMjobpw1OPrwTHLUbR%2BOJ75g6flPpjOr4QEN9Y7OJanE5FU5ps9f6vdRcvN0khh2locCc8oWMeaDY1zQCXupeB0Kb%2BzWCmWGMMp%2BrHFc6Y0qhbn1yhF2Pacn1VEjs5KPp8byCzjx4kqxQKL6dAWwFGw1oC0JfQ1AzaWQf3rep3BzaBqty/PJdW5YwJQ5eSXln8xk4xv8ZgrI532yre31V8%3D&iv=yo4RLWOgEoo%3D&hsutk=ac90921837407f16c1c804c72764ad77&utm_referrer=http%3A%2F%2Fclassic-migration-sandbox-28573.hs-sites.com%2Foil-tank-leak-remediation&canon=http%3A%2F%2Fclassic-migration-sandbox-28573.hs-sites.com%2Foil-tank-leak-remediation&__hstc=233546881.ac90921837407f16c1c804c72764ad77.1417176073543.1417176073543.1417176073543.1&__hssc=233546881.235.1417176073544&__hsfp=906693646)   ![leaking oil tank delineation](https://www.currenenvironmental.com/hs-fs/file-2151440252-jpg/images/delineation-resized-600.jpg?width=599&height=450&name=delineation-resized-600.jpg) Once the area (size 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.   #
