 Groundwater
is a potential migration pathway and is monitored by the United
States Geological Survey, as well as the INEEL M&O contractor.
Surface water does not flow off of the INEEL so the primary
pathway by which radionuclides can move off-site is through the air.
Consequently, air is a primary focus of ESER monitoring on and
around the INEEL. Particulates and Iodine-131
in air are measured weekly at 15 locations using low-volume air samplers
for the duration of the quarter. Moisture
in the atmosphere is sampled at four locations around the INEEL and
analyzed for tritium. Concentrations
of particulates in the air are obtained using PM10 samplers
at three locations. Air
sampling activities and results for the first quarter, 2001 are
discussed below.
