*** Proposed Site *** Apri l 2016 

### WAPPINGER CREEK Dutchess County , New York Dutchess County
 **Site Location :**  The Wappinger Creek s ite is locate d in a mixed residential and commercial/industrial area of the v illage of Wappingers Falls , t own of Poughkeepsie, and t own of Wappinger, New York

. The Wappinger Creek site is comprised of contaminated sediments from multiple sources

. The tidal portion of Wappinger Creek begins downstream of Wappingers Falls and extends for approximately two mil es downstream to the confluence with the Hudson River.

 **Site History:** Sediment contamination within the tidal portion of Wappinger Creek was identified by the s tate of New York in 2001, adjacent to and downstream of an industrial park located at the base of Wappinger Falls. A wide variety of i ndustrial activities have been conducted at the industrial park location for more than 180 years includ ing textile dyeing, manufactured gas plant (MGP) operations, metal plating, plastic mold injection, felt hat man ufacturing, ammunition production, chemical manufacturing and distribution, and several other industrial and commercial activities. Buildings within the industrial park associated with a metal plating facility had floor drains that discharged to Wappinger Creek . A former spill way and lagoon, which discharged to Wappinger Creek, received industrial wastes from the southern portion of the industrial park

. Portions of the industrial park itself are reported to consist of variable fill materials, including coal cinders from MGP activities.

 **Site Contamination/Contaminants:** The primary contaminant s of concern are mercury and polycyclic aromatic hydrocarbons (PAH s ), both of which are attributable to historical operations within the industrial park

. Other contaminants detected at elevated concentrations in the industrial park and in creek sediments include chromium , mercury and lead

.

 **Potential Impacts on Surrounding Community/Environment :**  The tidal creek is used for recreational boating and fishing for human consumption. The Wappinger Greenway, which includes the Wappinger Greenway Trail, runs along the bank of Wappinger Creek downstream from the industrial park to near the tidal creek’s confluence with the Hudson River. The Wappinger Greenway Trail links histor ical, cultural, natural, and economic resources of local and regional significance and p rovides access to portions of the creek contaminated with
mercury

. A narrow wetland area is located along the contaminated portion of Wappinger Creek

.  **Response Activ ities (to date):**  There have been several investigations and cleanups within the industrial park . H owever, mercury and PAH contamination remains adjacent to and downstream of the industrial park.

 **Need for NPL Listing:** The s tate of New York referred this site to the EPA. Other federal and state cleanup programs were evaluated, but are not viable at this time. The EPA received a letter of support for placing this site on the NPL from the s tate of New York
