Monitoring Well 1 11 Criteria-DRAFTO.doc Monitoring Well 1 11 (MW-i 1 1) IP-2 Transformer Yard sample analysis parameter selection criteria.
The water sample from Monitoring Well 1 11 (MW-i 1 1) located in the IP-2 Transformer Yard was analyzed for Tritium, Gross Beta and Gamma Spectroscopy. These parameters were selected for several reasons:
1.
Tritium is highly mobile in water/soil combinations, there is little or no interaction of the tritium with soil or water, and thus provides a sensitive indicator of plume extent.
- 2.
Gross beta is a good indicator of total non gamma emitting (such as Sr-90) radionuclide concentration
- 3.
Gamma Spectroscopy is a good indicator of gamma fission product and corrosion product presence.
- 4.
These analytical methods were within the capability of the JAF Environmental Laboratory at the required LLD values.
Following the positive identification of Tritium in MW-i1 1 1 water, an aliquot from the initial sample volume is being prepared for shipment to an off site vendor for additional analysis for Sr-89/90 and Ni-63.
Sr-89/90 was selected based on mobility in soil and Identification in FSB dirt samples. Ni-63 was selected based on identification in an FSB Crack water sample.
