The Route 561 Dump Site is one of three sites (including the United States Avenue Burn Site and the Sherwin-Williams/Hilliards Creek Site) currently under an EPA 1999 Administrative Order on Consent (AOC) for Remedial Investigation/Feasibility Study (RI/FS) activities with the Sherwin-Williams Company. The Route 561 Dump Site, located in Gibbsboro, New Jersey was proposed to the National Priorities List (NPL) on July 28, 1998 due to contamination from paint wastes. 

The 2.9-acre site is bound by a strip mall to the north, Clement Lake to the east, Route 561 to the west and vacant land to the south. An estimated 5,280 people live within one mile of the site. The White Sand Branch Stream originates within the site and flows south through the property. After traveling through an underground culvert beneath Route 561, the stream resurfaces as a distinct branch and continues to flow through a wooded area (eventually entering the United States Avenue Burn Site).

From the mid 1800s till 1977, John Lucas & Company and eventually the Sherwin-Williams Company operated a paint manufacturing facility (part of the Sherwin-Williams/Hilliards Creek Site) at a separate location in Gibbsboro, New Jersey.  Reports indicate that paint wastes and sludge were disposed of at the Route 561 Dump Site. 

Soil and sediment sampled from the site revealed the presence of elevated concentrations of lead and arsenic. In response to this contamination, EPA issued an AOC in November 1997 to the Sherwin-Williams Company to perform a Removal Action at the site.  Actions included measures to restrict access to the site and to implement certain engineering controls. Pursuant to the 1997 AOC, Sherwin-Williams covered three bare soil areas that contained high levels of soil contamination with an impermeable membrane and a layer of clean fill material and top soil to prevent direct contact with these areas.

Sherwin-Williams was also required to install silt fencing to prevent soil erosion into the stream and wetlands, enclose the site with a chain-link fence, and install an intruder alarm system, including video and sound surveillance. The work required for this immediate action was completed by December 1997. Periodic routine maintenance of the fence and security system is currently performed by the Sherwin-Williams Company.

Since 2005, the Sherwin-Williams Company, with EPA oversight, has conducted remedial investigation field sampling and other related activities at this and the other two sites. The sampling activities are designed to evaluate the nature and extent of contamination. Sampling results indicate the presence of metals, particularly lead and arsenic, in the site soils (both shallow and deep), sediments, surface water and groundwater. At the completion of the RI/FS activities, a Record of Decision selecting the cleanup approach for the site will be signed by EPA.
