Site Map




Remediation of the Bloody Brook Voluntary Cleanup Site is complete.  The work began at the most upstream portion of the site (the wooded area near the NYS Thruway) in 2014 and was completed in spring 2017.  

During that time, approximately 39,000 tons of soil and sediment were removed from the brook channel, side banks and properties adjacent to the affected areas.

After completing the majority of remedial construction from 2014 to 2016, throughout the months of March through June 2017, Lockheed Martin’s remedial contractor (AECOM) cleaned up soil and restored an area outside of the brook at one property (an apartment complex) just off of Old Liverpool Road to complete the project.

What’s Next for the Site

To complete the requirements of the March 2014 Decision Document, Lockheed Martin is compiling the Site Management Plan (SMP) and Final Engineering Report (FER). 

The SMP provides a general description of the site, notes the controls in-place and describes the nature and extent of the remaining contamination at the site.  As part of the SMP, Lockheed Martin will send notices annually to property owners within the site where residual cadmium remains below remedial excavation depths (that is, below 4 feet in residential areas). 

These notices will remind property owners of the potential presence of residual cadmium.  It will provide detailed information about where it could be encountered and what to do if the owner should need to dig within these areas.

The FER documents the complete remedial program implementation and is required to receive a certificate of completion or closure letter from the New York State Department of Environmental Conservation (NYSDEC).  Implementation of the SMP is the last phase of a remedial program, which begins with the closure letter. Site management ensures the safe (re)use of properties where contamination remains in place.

Lockheed Martin is now focusing on site monitoring, restoration and planning for the five year maintenance and monitoring period ahead.  Annual inspections will occur for five years following completion of restoration activities to ensure no erosion of the channel and banks is occurring and that the vegetation is growing as intended. 

These annual inspections will comply with the March 2014 Decision Document prepared by the NYSDEC, property-specific restoration agreements and the NYSDEC approved restoration work plans for the site.  As needed, based on these inspections, vegetation may need to be replaced and the brook side banks may require minor repairs.

Crayfish in the brook will also be sampled beginning in 2018, and again in 2020, to assess their cadmium concentrations following the completion of remedial activities. 

Results from samples collected before remediation will be used as a baseline for comparison of the cadmium concentrations.  This data will help determine the effectiveness of the site remediation in mitigating potential cadmium impacts to the brook.
