Phase II Environmental Site Investigation
Fort Hamilton is home to the Headquarters of the U.S. Army Corps of
Engineers North Atlantic Division, the New York City Army Recruiting
Battalion, Army Reserve, Army National Guard and Air National
Guard elements. CORE was contracted to complete environmental site
sampling. The investigative work was located at the vicinity of former
Buildings 103 and 107. CORE provided all labor, materials, equipment
and oversight to complete 12 soil and 12 groundwater samples to be
analyzed by a certified laboratory.
CORE performed seven (7) soil borings from former Building 103
gasoline storage tank site and recorded photo ionization detector (PID)
levels. CORE collected one soil sample at the highest recorded PID
concentration of total orgaic vapors, and one soil sample at the water
table for a total of fourteen (14) soil samples, two soil samples per boring.
CORE also collected one groundwater sample per boring for a total of
seven (7) groundwater samples.
CORE performed five (5) soil borings from former Building 107 fuel oil
storage tank area. CORE collected one soil sample at the highest recorded
PID concentration of total organic vapors, and one soil sample at the
water table for a total of ten (10) soil samples, two soil samples per boring.
CORE collected one groundwater sample (at groundwater) per boring for
a total of five (5) groundwater samples.
The soil and groundwater samples were tested using EPA methods 8260
and 8270, for parameters identified in the New York State Department of
Environmental Conservation (NYSDEC) Table CP-51. CORE prepared
a report with boring logs, sampling logs, data tables with comparison to
appropriate standards, criteria and guidance values (SCGs).
After a review of the data collected during the subsurface investigation, CORE prepared an opinion to determine if underground storage tank (UST) and/or historical activities on this base had an environmental impact on subsurface soil, and or groundwater. CORE noted that the soil near building 103 was free of contamination and recommended that further investigation be performed near building 107 to determine the extent of contamination.
