FW: Potentially more tritiumdiscovered at,Peach'Bottom Neil, Diane, Nancy, Doug, FYI onisome.r indications of tritium at P.B. We'll have more info ,tomorrow. I've already engaged'DRS,.
Important points to note right now:
"nomiaatjon inthis recoruwas delsied in apcordance with the Freedom of bnbo~Maalo AcL
OOne testilocation had 122, 000 pCi/L tritium. A confirmatory sample has not been analyzed'yet.
Expect reult tomorrow.
No indications that there is an unmonitored release atfthis point. Outfall locations are LDA but any
, tritium would be very diluted at the outfall.
PB fouid this as part of an initiative they have been undertaking forthe last year. This started when PB found -4000 pCi/I in a well adjacent to the inner screen house,
- PA and MIDbEPare being given courtesy notifications by PB, on this issue.
I have a site map with a!more precise location of the wells. More to.follow tomorrow.

For.Geo-probe #3 the results were 122,748 pico Curies of Tritiunm.
~For Geo-probe #4the results were ,22,I100 pico Curies of 'Triti'umi Note - these are just preliminary results and they have sent the samples'out for Confirmatory samples., Bill did indicat* that he plans to give.RichJaanati and the State of Maryland a call just to alert them of'thbepotential
-results.*

.River? to ensure that they are nOt seeing anything there. Bill: indicated that,they'(PB) still feel ,that this ýcould be water from the, Unit a CST.
