In 2014, Lockheed Martin began cleanup activities in the most upstream portion of the Bloody Brook remediation site (the wooded area near the NYS Thruway).   Approximately 624 truckloads (approximately 13,000 tons or 9,000 cubic yards) of soil and brook sediment were removed from this area in 2014.  We completed removal of the dry brook sediment and portions of the side banks, and the brook bottom and side banks were restored. Also, three new wetland/pond areas were created to create new brook capacity for flood control during high flow conditions as well as enhancing habitat for local wildlife. Planting of trees and shrubs to restore the work area also has taken place.  (See the August, October and December 2014 editions of the “Bloody Brook Voluntary Cleanup Newsletter” for photos and more information.)

After temporarily shutting the site down for the winter months, Lockheed Martin has restarted activities at the site.  The 2015 cleanup effort in the residential areas will begin in the upstream portion and continue downstream through the residential areas.  During 2015, soil, sediment and side banks along the brook will be removed and restored.  The gabion baskets (metal caging filled with rocks) that line the brook banks between the Midwood Drive access area and Brookview Lane will be removed.  The gabion baskets will not be replaced but instead the brook banks will be restored with a more natural, gentle slope and with vegetation as well as stone.

In addition, the culverts which move the brook underneath Brookview Lane, Sunflower Drive and Floradale Road will be replaced.   Residents in the active culvert construction areas will be notified by phone or mail of the work and any new traffic patterns through the neighborhood.  A traffic control plan will be followed for each culvert to ensure the safety of the community, and all local emergency facilities will be informed of the new traffic pattern in the neighborhood.

As in 2014, continuous air monitoring is conducted for dust to ensure minimal impact to residents and compliance with New York State regulations.  If at any time a dust monitor indicates an exceedance, work would be stopped immediately and not continued until measures have been taken to correct the issue.

Look for more information this summer as the project continues in 2015 in the “Bloody Brook Voluntary Cleanup Newsletters” posted on this website as well as outside the access points to the Bloody Brook remediation site.


In 1947, General Electric - a Lockheed Martin heritage company - opened its doors at Electronics Park in Liverpool, N.Y., a suburb of Syracuse. The facility became part of Martin Marietta in 1993, and part of Lockheed Martin in 1995 after Martin Marietta and Lockheed merged to form Lockheed Martin Corporation. In the mid-1990s, during an environmental investigation of tributaries that flow into Onondaga Lake, the New York State Department of Environmental Conservation (NYSDEC) detected elevated cadmium levels in sediment in the West Branch of Bloody Brook, which flows under Electronics Park and discharges into the lake.

NYSDEC found elevated levels of cadmium, a metal formerly used in plating lines at the facility, in the brook’s sediment but not in surface water, indicating that a release had taken place many years before. Following state testing, Lockheed Martin began voluntary environmental investigations in 1996. In 1997, after identifying the locations with the highest levels of cadmium, Lockheed Martin removed 325 tons of sediment from a 750-foot stretch of the West Branch of the brook closest to the facility.

Between 2001 and 2007, Lockheed Martin collected more than 1,000 soil samples further downstream and found elevated levels of cadmium at depths ranging to 15 feet. The New York State Department of Health reviewed the results of the sediment and soil sampling and did not identify any immediate human health concerns. However, the Onondaga County Health Department issued an advisory for residents to avoid contact with the brook. Lockheed Martin entered into a Voluntary Cleanup Agreement with NYSDEC in 2002.

After the investigations, Lockheed Martin created a Remedial Action Work Plan (RAWP) that it submitted to NYSDEC in March 2005. NYSDEC proposed increasing the scope of the plan, which Lockheed Martin completed in September 2009. The RAWP called for excavating sediment and soil from the brook channel, side banks and properties (wooded, residential and municipal areas) adjacent to the West Branch of Bloody Brook.

In addition, at the request of Onondaga County, Lockheed Martin was involved in removing sediment from culverts along the West Branch of the brook in 2008 and assisted with soil removal from properties included in a stormwater drainage improvement project in 2009. Under Lockheed Martin’s Interim Remedial Measure (IRM) Work Plan, which NYSDEC approved in April 2008, Lockheed Martin removed sediment from four sets of culverts.

Since the 2009 RAWP submittal, Lockheed Martin and NYSDEC determined that additional soil samples needed to be collected from properties located near the current West Branch of the brook and the former brook channel to further refine the RAWP and to define the boundaries of the areas where soil removal has been proposed. Lockheed Martin submitted a sampling work plan to the NYSDEC in February 2011, and it was approved in March 2011. As outlined in that sampling work plan, more than 700 additional soil samples were collected in 2011.
