- 1. H3 bounding isopleths / data represent upper bound values measured over both depth and time (available results for sample dates through 8/28/2007). As such, the "plume" is an overstatement of contaminant levels actually existing on-site at any time.
- 2. Tritium activity as high as 601,000 pCi/L, as measured on 11/22/2005 in MW-30 open borehole prior to multi-level well completion.
- 3. Tritium activity as high as 44,400 pCi/L, as measured on 6/27/2006 in MW-32 open borehole prior to multi-level well completion.
- 4. This upper bound Tritium concentration was obtained from the RW-1 open borehole during a pumping test.
- 5. Tritium activity as high as 337 pCi/L, as measured on 7/19/2006 in MW-52 open borehole prior to multi-level well completion.
- 6. Tritium activity as high as 16,000 pCi/L, as measured on 8/25/2006 in MW-55 open borehole prior to multi-level well completion.

- 1. Sr-90 "bounding isopleths" / data represent upper bound values measured over both depth and time (available results for sample dates through 8/28/2007). As such, the "plume" is an overstatement of contaminant levels actually existing on-site at any time.
- 2. Sr-90 activity at MW-111 and MW-33 may be due to desorption of residual Sr-90 from backfill used in the Transformer Yard.
- 3. Sr-90 only detected in MW-30 during pumping test of RW-1 on 11/29/06.
- 4. A Sr-90 value of 0.9 was measured on 5/24/2006 in MW-31 open borehole.
- 5. Three discrete isopleths have been drawn around MW-39, 41, and 43 given measured concentrations greater than 2 pCi/L. It is expected that similar concentrations exist at other locations along the legacy piping alignment in addition to the locations shown.
- 6. The low Sr-90 concentrations measured in these wells are consistent with that expected due to residual levels remaining as the legacy plume has attenuated over time.

LEGEND Data Notes:
- 1. Cesium, Cobalt, and Nickel bounding data represent upper bound values measured over both depth and time (available results for sample dates through 8/28/2007). As such, these data are an overstatement of contaminant levels actually existing on-site at any time.
- 2. Bounding values for Cs in MW-30 and MW-31 were measured just after the RW-1 pumping test.
Note:
Contours developed from limited data available on 6/1/2007. Actual elevations may vary from conditions shown and the actual distribution of piezometric heads is likely more complex than indicated.
General Notes:
- 1. Base map was developed from an untitled electronic file provided by Badey & Watson Surveying and Engineering, P.C., Dated 2/3/06; CAD file name : "GZA.dwg".
- 2. Additional legend on Figure 1.3.
