USACE/National Park Service – Great Kills Park, Staten Island, NY: Time Critical Removal Action

Tidewater together with SDC as the primary sub-contractor conducted radiological characterization and a removal action involving medical and radioactive waste at the 260 acre Great Kills Park, Staten Island, New York under a Time Critical Removal Action (TCRA) for the USACE/National Park Service. Radiological surveys performed by Tidewater identified that the radiological and medical waste were associated with a former landfill operation at the site.

Tidewater and SDC performed environmental sampling and a removal action at over 30 contaminated areas. The team also: developed a radiological risk assessment for purposes of evaluating site risks associated with activities conducted by members of the public, park employees, and first responders; provided technical support to USACE and NPS for public meetings including presenting project status and findings to residents and the local U.S. Congress representatives; disposed of waste generated from the removal action at a licensed disposal facility; and performed post remediation surveys to verify the effectiveness of the removal action.

All data were reported and summarized in a Final TCRA Completion Report. Tidewater also conducted a reassessment of all radiological survey data collected for the project. This including a review of the GIS data and a statistical analysis of the data for the entire project. The database consisted of over 260 data sets each containing thousands of data points and the development of 4 new graphical displays (contour maps) for each data set. Tidewater performed entire removal action including issuing the final report within budget and an extremely tight schedule by self-performing all aspects of the work including field work and yellow iron work, and reporting.
