Peconic River Project
The Peconic River receives discharges from the Lab's sewage
treatment plant. During
the remedial investigation, elevated levels of heavy metals (such as
mercury, copper, and silver), organic chemicals (such as
polychlorinated biphenyls, or PCBs), and low levels of pesticides
(such as DDD, a product of DDT degradation) and radionuclides were
detected in Peconic River sediment. Most of the contaminants were
found in the top six inches. As expected, contaminants are more
prevalent in areas where more sediment is deposited by the river and
decrease with distance downriver.
