1. Quarterly Tritium isopleths and activity values are yearly rolling arithmetic averages of the current and preceding three quarters' data. Only values greater than the MDC are used in this average, thus adding a degree of conservatism to the subsequent dose computations.

2. Illustration of contaminant plume is a schematic representation only. In reality, the geologic bedrock formation is over 99% solid, crystalline rock, with the contaminated water contained only in the remaining (less than 1%) interstitial space (i.e. fractures).

3. Foundation drain sampling locations, for which investigation levels are not applicable.

4. Historically elevated Tritium levels in MW-42-49 observed during Q1 2009 were consistent with leakage visually identified on 03/07/2009 (and terminated immediately thereafter) from the waste distillate tank valves located within the Unit 1 fuel storage building. Data trends through Q1 2010 indicate that the observed Tritium peaks in MW-42-49 and downgradient wells associated with this release have dissipated through the groundwater flow system.

5. Elevated levels of Tritium detected in MH-9 and MH-10a during routine 80-10 Effluents Program sampling on 1/15/2010 appears to have originated from a Q4 2009 transient leak in temporary RWST / R.O. skid connection hoses, which flowed into MH-9. It also appears that this release entered the well vault for MW-32, and may have penetrated the well casings and entered the subsurface around the monitoring installation.

6. Please refer to Figure 6 for the drawn Unit 1 Tritium plume isopleths. The likely causation of the Q2 2011 Tritium increases in multiple Unit 1 monitoring installations was a transient Sample Sink Overflow and subsequent floor flooding in a Unit 1 Chemical Systems Building sample room on the 53 elevation.

7. Elevated levels of Tritium initially detected in U1-CSS, MW-39, MW-46, MW-54, MW-56 and MW-57 during the Q2-2011 sampling event appear to have originated from a Q2 2011 Sample Sink Overflow and subsequent floor flooding in a Unit 1 Chemical Systems Building sample room on the 53 elevation.

8. Elevated levels of Tritium initially detected in MW-31 during the Q2 2012 sampling event appear to have originated from a leak in an existing Unit 2 Maintenance Outage Building (MOB) drain line. This double contained, stainless steel line was used to service the R.O. skid at its new location in the MOB during the 2012 Unit 2 refueling outage.

9. Elevated levels of Tritium initially detected in MW-42-49, MW-53-82 and U1-CSS during the Q4 2013 sampling event appear to have originated from an overflow of the Unit 1 Containment Spray Annulus (CSA).

10. Elevated levels of Tritium initially detected in Q2 2014 supplemental samples from MW-31 and MW-32. Release originated from transient flooding of the Unit 2 Fan Building 51 floor during 2014 refueling outage discharge of RCS drain down to a partially obstructed floor drain.
