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.
  • All of the wooded areas were restored with grass, shrubs and trees as well as three new wetland/pond areas that were made to create new brook capacity for flood control during high flow conditions as well as enhancing habitat for local wildlife.
  • See the August, October and December 2014 editions of the “Bloody Brook Voluntary Cleanup Newsletter" for photos and more information.

The 2015 cleanup effort began in April in the wooded area where the 2014 activities left off, and continued downstream through the residential area up to the Floradale Road brook crossing.  

  • Approximately 870 truckloads (approximately 21,000 tons or 14,000 cubic yards) of upland and side bank soil and brook sediment was removed. 
  • The gabion baskets (metal caging filled with rocks) that lined the brook banks between the Midwood Drive access area and Brookview Lane were also removed and restored with a more natural, gentle slope and with vegetation as well as stone.
  • All disturbed areas were restored with grass, shrubs and trees.  In addition, any fences or sheds disturbed on residential properties were replaced.
  • The aging, corrugated metal culverts which move the brook underneath Brookview Lane, Sunflower Drive and Floradale Road were replaced with concrete box culverts which also included new pavement and guardrails.  
  • See the June, August and October 2015 editions of the “Bloody Brook Voluntary Cleanup Newsletter” for photos and more information.

In 2016, remedial construction activities resumed in May beginning at the downstream side of the Floradale Road brook crossing. 

  • Contractors have removed approximately 120 truckloads (2,900 tons or 1,900 cubic yards) of soil and sediment from the site through July 2016. 
  • The corrugated metal culverts underneath Pearl Street and Town Garden Drive were repaired and lined with concrete.
  •  Monitoring and watering of restored upstream areas has been necessary due to the lack of rain this summer.

Upcoming activities include:

1947  General Electric (a Lockheed Martin heritage company) opened its doors at Electronics Park.

1993  The facility became part of Martin Marietta in 1993.

1995  The facility became part of Lockheed Martin after Martin Marietta and Lockheed merged.

1996  The New York State Department of Environmental Conservation (NYSDEC), during an environmental investigation of tributaries that flow into Onondaga Lake, detected elevated cadmium levels in sediment in the West Branch of Bloody Brook, which flows under Electronics Park and discharges into the lake. Cadmium, a metal formerly used in plating lines at the facility, was found in the brook’s sediment but not in surface water, indicating that a release had taken place many years before.

1996  Following NYSDEC testing, Lockheed Martin began voluntary environmental investigations.

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.

2001-2007  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 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.

2002  Lockheed Martin entered into a Voluntary Cleanup Agreement with NYSDEC.

2005  Lockheed Martin created a Remedial Action Work Plan (RAWP) that it submitted to NYSDEC, and they responded by proposing an increase in the scope of the plan.

2008  At the request of Onondaga County, under the NYSDEC approved Interim Remedial Measure (IRM) Work Plan, Lockheed Martin removed sediment from four sets of culverts along the West Branch of Bloody Brook.

2009  Lockheed Martin assisted with soil removal from properties included in an Onondaga County stormwater drainage improvement project.

2009  Lockheed Martin submitted a revised RAWP which called for excavating sediment and soil from the brook channel, side banks and surrounding properties adjacent to the West Branch of Bloody Brook.

2010-2011  Lockheed Martin and NYSDEC determined that additional soil samples needed to be collected from properties located near the West Branch of the brook and the former brook channel to further refine the RAWP and the soil removal area.

2011  Lockheed Martin submitted a sampling work plan to the NYSDEC which was approved, and more than 700 additional soil samples were collected in 2011.

2013  Lockheed Martin submitted a revised RAWP to NYSDEC which incorporated the results of the 2011 soil sampling.

2013  To further define the soil removal area that was proposed, Lockheed Martin collected additional soil samples from some residential properties.

2013  NYSDEC completed its review of the 2013 revision to the RAWP, and based on its content, developed a Proposed Decision Document for the site which was made available for public review.

2014  After considering public comments, NYSDEC issued a final Decision Document which included responses to public comments and the administrative record for the site.
