Document, Report, or Work plan Review - other |
DEC provided review comments for the Draft Site Characterization report for Site UST1578-3_B1812. The report concluded that subsurface soil beneath and in the immediate vicinity of UST 15783 is contaminated with EDB above migration to groundwater Method Two cleanup levels. EDB was not detected in groundwater at Site. The review concluded that EDB contamination is not fully delineated at the Site.
DRO, GRO, Benzene and several VOC’s and SVOCs above DEC cleanup levels were identified up-gradient of the UST 1578-3 tank location within the Site B1812. DRO contamination at Site B 1812 was consistently identified at 29 feet bgs. DRO was also identified in vadose soil within the B 1812 site boundaries at 5’ and 10’ bgs. Benzene above the Table C cleanup level was detected in several grab groundwater samples from borings within Site B 1812 at 13 – 14 and 41 feet bgs. VOCs, TCE and Methylene chloride were also detected at several locations within the B 1812 site boundaries at 5 – 10’ bgs. EDB was not detected in soil or groundwater at Site B1812. |
