Uplands Area:
The uplands area continues to be maintained by the NJDEP Bureau of Maintenance
and Monitoring. Maintenance measures include cutting Uplands Area grasses
and insuring the integrity of the existing cap by routine inspections.
Sampling ground water at the newly installed monitor wells located in
the capped uplands and at a background location to ascertain ground water
quality and flow direction will also be conducted.
Westerly Wetlands, Northerly Wetlands and Tar Patch Area:
Excavation and off-site disposal of approximately 55,000 tons of polychlorinated
biphenyls (PCB) and lead contaminated soil from the Northerly Wetlands
and Tar Patch Area was completed this spring. Excavation was followed
by a wetlands restoration project that included the planting of approximately
9,500 bushes, small trees and groundcover in the two areas. A replanting
of approximately 1,300 plants will begin this fall to achieve an 85% success
rate for the new growth.
Longterm Monitoring:
NJDEP continues to maintain the sedimentation basin, including mowing
and upkeep of the berm and gravel road around the basin. Quarterly sampling
of the surface water and sediments in Burnt Fly Brook is also continuing
as usual. PCBs and lead have consistently been reported as being either
not detected or at very low levels.
Long term monitoring will begin once all remedial activities have been
completed. The monitoring will include sediment and surface water sampling
in the Westerly Wetlands, Burnt Fly Brook and the Sedimentation Basin,
and ground water sampling at monitor wells around the Sedimentation Basin
and in the Uplands Area. EPA will perform a one-time biota sampling event
of small mammal species in the Westerly Wetlands during the spring of
2005 and compare the results to the 1992 Report (Final Report Ecological
Assessment for Burnt Fly Brook, Marlboro, NJ June 1992). Newly created
wetlands within the Northerly Wetlands and Tar Patch Area will be monitored
for 7 years to insure proper restoration of the wetland environment. The
goal of the Long Term Monitoring Plan is to assess the effectiveness and
performance of the remedial action and insure the protection of human
health and ecological receptors.
