Final Release D_LHL Vte 300 (UsDoE) <br /> State and Local Health Data <br /> State and local health data were not reviewed because the surrounding public was not found to be <br /> exposed to contaminants originating from Site 300. <br /> Environmental Contamination and Pathways Analysis <br /> Introduction <br /> This section discusses the various chemicals and radioactive materials (i.e., contaminants) <br /> evaluated for this site,how persons might come into contact with them, and what populations are <br /> potentially exposed. These discussions are presented for groundwater, air, surface water, soil and <br /> sediment, and food and biota. <br /> j%ft WURfPA77-"A1rS <br /> s� <br /> N.

ATSDR scientists <br /> first determine if a chemical or radioactive substance in water, air, soil, or biota(plants and <br /> animals) should be considered a "contaminant of concern."The criteria we use include <br /> 1. environmental levels exceeding media-specific comparison values, <br /> 11 <br />
