When Would I Need Soil Remediation?

• Before jumping into the soil remediation
  process, let's determine when it is required.
  Unfortunately, the way the industry works is that
  when your oil tank is removed, if it fails
  inspection, 9 out of 10 companies are going to
  recommend what's called a soil remediation
  project.

• Without having any analytical results, if a
  company offers you soil remediation as the next
  step in the process, you need to run in the other
  direction! This is a major red flag, as soil
  remediation is only required when contamination
  is above the cleanup standards. According to the
  New Jersey Department of Environmental Protection
  (NJDEP), you're allowed to leave contamination in
  the ground as long as you can prove that it's
  under the cleanup standards.

• Contaminated Soil Removal
• If your tank fails the inspection, we will take
  one sample of the bottom of the tank and send
  that to a state-certified lab. Depending on the
  level of that contamination, we would come back
  to you with a few options when it comes to
  remediation and removal

5
Soil Investigation

• One option we would recommend is soil
  investigation with oversight from a subsurface
  evaluator. This project consists of us coming out
  and probing around to grab six samples from the
  previous tank excavation. Those six samples will
  then be sent to a state-certified lab. As long as
  those results prove that contamination is below
  the limits, our subsurface evaluator will write a
  report for the NJDEP to review, which then they
  would return a No Further Action letter your
  clean bill of health.

Soil Remediation

• The other outcome is that if that initial sample
  was over the cleanup standards (1,000 parts per
  million), we typically recommend soil
  remediation. The soil remediation process
  consists of us excavating the soil into a dump
  truck and bringing it to a facility to get it
  weighed in and subsequently disposed of. We would
  then sample the excavation area to determine and
  confirm that we got all the contamination out.
  The soil is field-screened onsite.

• Once we feel confident that we got it all out or
  down to an acceptable level, we will backfill the
  excavation with certified clean fill up to
  surface grade. Once we get those sample results
  back, proving that we did indeed get all the
  contamination out, our subsurface evaluator will
  then compile a report for the NJDEP to review.
  The NJDEP will then issue you a No Further Action
  letter. That is a simple soil remediation process.

8

• That's the best-case scenario with soil
  remediation. We come in, dig out the contaminated
  soil (usually by 1100 p.m. or 1200 a.m), take
  our samples, backfill the excavation up to grade,
  and are out of there within eight hours.

Groundwater and Bedrock

• There are certain projects where we encounter
  either groundwater or bedrock. Bedrock is what it
  sounds like if we're digging down to
  contamination and we hit rock, and we cannot
  excavate through it, the DEP will require that we
  drill through that rock to test the groundwater.
• The other outcome is encountering groundwater.
  If we're excavating the contaminated soil and the
  excavation starts to suddenly fill up with water
  because we're very close to a river or a lake or
  a stream, the State of New Jersey will require
  that we investigate, put a well in, and test that
  groundwater.

How Much Does it Cost to Remove Contaminated Soil?

• The cost of contaminated soil removal ranges
  from a few thousand to six-digit figures. The
  settled cost depends on a variety of factors,
  including what we find amid our examination
  procedure as well as the resources and equipment
  we implement.
