How do I know if my soil is REALLY contaminated?

When an inspector determines a tank shows signs of corrosion or obvious holes, they will fail the inspection. If that happens our subsurface evaluator will come to your site and take soil samples. The results will determine if there is contamination and if so the extent of the contamination. Soil testing results are typically ready in about two weeks, although may be expedited in the event of a time constraint like a closing.

The Process of Removing Contaminated Soil

● If the township inspector fails your underground storage tank removal inspection, a DEP Case needs to be opened. Contaminated soil may shows signs of staining and/or a strong odor.
● When an inspector fails an inspection our subsurface evaluator or LSRP will dispatch to the site. The soil that shows obvious signs of contamination will be excavated and stockpiled on heavy gauge plastic sheeting on the site.
● Soil sample testing will then be performed on that stockpile to determine the type of contaminants.   Samples will also be taken from the sides and bottom of the excavation to determine the all of the contamination has been removed and the remaining soil is free of contamination.
● Once the soil sample results are returned and the excavation has been determined to be free of contamination, the sample results of the contaminated soil will be forwarded to a nearby soil disposal facility for approval to dispose of the contaminated soil that was stockpiled.
● Once facility approval has been obtained, the contaminated soil will be scheduled to be loaded onto a truck or trucks and brought to the facility for disposal, whereupon a manifest will be issued. These manifests are necessary to submit to the DEP so the open case can be closed and and NFA letter (No further Action) can be obtained from the DEP.

Why Would I Need Groundwater Remediation Services?

These services are needed if your contamination has seeped into the groundwater

What happens if my contamination reached the groundwater?

If your underground storage tank has leaked and the contents have seeped not only into the soil but also into the groundwater, you may need a monitoring well which would be determined by the subsurface evaluator or LSRP. Samples will be taken of the groundwater and sent out for testing. Once the extent of the contamination levels is determined, remediation may be needed. Future well monitoring and groundwater remediation may also become necessary, depending upon the extent of the contamination.
