Soil analyzed for asbestos using polarized light transmission and transmission electron microscopy

The initial sampling event was conducted by EPA’s Environmental Response Team (ERT) on October 2000. Samples were collected from the surface (0-3") and subsurface (18-24") at nine locations and at an additional six locations for surface samples only.

All of the samples collected were analyzed by both polarized light microscopy (PLM) and transmission electron microscopy (TEM) via NYS ELAP 198.4 methodologies. These samples were found to contain concentrations of up to 2.9% tremolite asbestos and up to 3.9% chrysotile asbestos.

In March 2001, the EPA-ERT returned to the Site to perform additional sampling of selected surface and subsurface grid locations previously sampled during the October 2000 investigation. Thirteen samples were collected from selected grid locations and concentrations of up to 4.5% tremolite asbestos and up to 2.7% chrysotile asbestos were detected.
