NYSDEC Oversight

The NYSDEC provides oversight of activities conducted by the major responsible parties at various Greenpoint petroleum remediation sites in Brooklyn, New York. NYSDEC’s subcontractor (Ecology and Environment Engineering and Geology P.C. [E&E]) conducts bi-weekly field oversight of PRP activities to assist NYSDEC in developing a better understanding of the day to day investigation and remedial activities that occur in the Greenpoint area and report any pertinent issues to NYSDEC’s project manager.

The following sections summarize recent activities observed at the various Greenpoint remediation sites in Brooklyn, New York.


Date of Oversight Observation: September 11, 2019

  2. Continuation of treatment system tank cleaning activities.
  3. Continuation of force main jetting activities.

As a result, further testing is required to determine the issue moving groundwater from the recovery wells to the treatment system.
  2. Antea informed E & E that a pressure increase was detected at MW-24 today and a blockage was removed from the NAPL line and the well is back to normal operation.
  3. E & E and Antea collected a sample of the on-site effluent for visual observation and compared it to a previously collected sample taken from the Newtown Creek in the vicinity of the outfall.

 Planned Activities

  1. Routine treatment system maintenance.
