EIGHTEENMTT E CREEK
Niagara County, New York
(?) Site Location:

The Eighteenmile Creek site is located in Niagara County, New York, on the south side of Lake Ontario. The
watershed includes the two main tributaries, the East Branch and the Gulf, and minor tributaries. Much of the flow in
the main branch of Eighteenmile Creek comes from water diverted from the New York State Barge Canal (NYSBC).
The creek flows north for approximately 15 miles and discharges into Lake Ontario in Olcott, New York.
jx Site History:
Eighteenmile Creek has a long history of industrial use dating back to the 19th century. In Lockport, New York, where
the creek originates, four industrial or former industrial facilities (i.e., Flintkote Plant; United Paperboard Company;
Upson Park; and White Transportation property), as well as the NYSBC, have been investigated. The area
encompassing these properties and the associated reach of Eighteenmile Creek (i.e., from NYSBC downstream past
the Flintkote Plant) is referred to as the Eighteenmile Creek Corridor. There are several other industrial facilities and
inactive hazardous waste sites located along or in the vicinity of Eighteenmile Creek. Investigations have confirmed
the presence of polychlorinated biphenyls (PCBs) and other contaminants throughout most of Eighteenmile Creek but
specific sources of contamination have not been definitively identified. The Burt and Newfane Dams, both located on
Eighteenmile Creek downstream of the Eighteenmile Creek Corridor, may serve as areas within the creek where
contaminated sediments accumulate.
I Site Contamination/Contaminants:
Sampling indicates that Eighteenmile Creek sediments are contaminated with a variety of pollutants, including the
metals mercury, lead, zinc and copper; pesticide/insecticides; PCBs; and dioxins and furans. PCBs are the primary
contaminants in sediment samples collected from the creek. Although the highest PCB concentrations have been
reported within the Eighteenmile Creek Corridor, sampling data indicate that the sediment contamination extends
approximately 12.71 miles downstream, just south of Burt Dam.
