Dear Peconic River Working Group:
This letter recalls some highlights from our January 22 meeting, and announces our next standing meeting.
HIGHLIGHTS FROM OUR JANUARY 22 MEETING
Skip Medeiros, the Peconic River Project Group Manager, opened the meeting with a status on risk assessment. Of particular interest is that the project team is preparing a response to the regulators to reconcile fish consumption rates to be used in scenarios of the risk assessment.
Next, Kevin Shaw, the Project Manager, discussed the cleanup technology of "Sediment Removal and Wetlands Reconstruction." Work is being done with the Department of Environmental Conservation (DEC) to identify ways to access Area D, a single upland area, to ensure the least amount of disruption. Based on comments from the DEC, the project team anticipates removing 7-12 small trees to enable vehicles to access the site. Kevin is also working to create a re-vegetation plan. Much of this plan will be based upon input from members of the working group and regulatory agencies staff members. Pointing to a large map of the area, Kevin said that after removing contaminated sediment he wants to re-vegetate the area with local plants. He requested input from the working group toward that end. During open discussion, significant points included the following:
Skip next spoke about the preliminary data from the native plant phytoextraction screening study. Skip explained that the bioaccumulation factor of the contaminants in the plants has to be high for the technology to be effective. The bioaccumulation factor exhibited by the native plants evaluated is quite low. Significant points included the following:
Further work is being done on the phytoextraction analytical results to verify calculations and to develop a written report before conclusions are final. Skip also reported to the working group that the CAC had recommended by consensus vote that we not go forward with the electrochemical technology. BNL and the DOE are now formalizing that decision.
OUR NEXT STANDING MEETING
Our next standing meeting will take place on February 26, 2002 from 6:30-8:30pm here at Brookhaven National Laboratory, in Berkner Hall, Room "B". Skip will not be present at the February 26 meeting.
