Contaminated Soil Remediation
-from beneath
foundation |
|
CLIENT: |
Traveler's Insurance,
Edison Township, Middlesex County, NJ |
|
DETAIL: |
Removed
oil tank from beneath addition foundation. Oil migration, spread by
shallow groundwater, was mapped by others and was confirmed to lie along
footing of original structure, requiring undermining entire addition.
Anco installed large I beams and, utilizing house jacks, supported
addition on temporary footings and columns that extended beyond the
building footprint. Groundwater monitoring confirmed non-actionable
contamination levels. Anco installed new footings and foundation, and
restored the site to its original condition.

Remediation
-from beneath foundation involving deck reconstruction |
|
CLIENT: |
NJ Manufacturers,
Montville, Morris County, NJ |
|
DETAIL: |
A badly
leaking oil tank located beneath a large deck impacted shallow
groundwater and flowed along he foundation, beneath the house and under
the driveway. The deck was removed and the worst contamination was dug
out with dewatering and hydraulic control over underlying groundwater. The
house was sectionally underpinned, then dug out and quickly concrete
filled in wide sections. Oil metabolizing microbes were utilized to
finish off trace amount of residual petroleum. Floor slab, driveway and
foundation drain replacement all included in the site restoration phase.
Anco also rebuilt the 12'x16' second floor deck with full stairway,
utilizing Anco carpenters.

Contaminated Soil
Remediation
-from beneath basement floor slab |
|
CLIENT: |
Preferred Mutual Insurance,
Carteret, Middlesex County, NJ |
|
DETAIL: |
Badly
leaking sub-slab oil lines discharged hundreds of gallons of #2 oil
beneath the basement floor. Oil was found to lie beneath the entire
house. An access ramp was cut to enable heavy equipment access. A
conveyor was utilized to lift contaminated soil and load trucks
directly. Sectional underpinning of the foundation ensured structural
integrity. Alternating 4' wide foundation sections were dug out,
sampled, and re-poured with concrete. New footings, foundation, floor
slab and heating system completed the site restoration, all by Anco
crews.

PROJECT: |
Groundwater Remediation
-with commingled contamination
sources |
|
CLIENT: |
Chubb Insurance, Hoboken,
Hudson County, NJ |
|
DETAIL: |
Oil
contamination from leaking UST commingled with oil from neighbor's
leaking UST. A pneumatically controlled free product skimming system was
installed to remove the 9" floating free product layer. This was
followed by use of a peatwick absorbent system. Weekly, the biweekly,
then monthly peatwick element change-outs satisfied NJDEP corrective
measure implementation requirements yet limited treatment to small area
without influencing/disturbing nearby plumes. While alternative remedial
approaches (i.e., EFR or pump & treat) would more quickly remediate the
site, project duration was less a factor than exceeding policy limits,
therefore this approach was deemed the most viable for the site.
