“…The pH values measured i n the second sampling campaign f o r the waters from the flooded K West Basin canisters range from 6.34 t o 11.85 with a mean o f 8.58 (Trimble 1997b). The n i t r a t e concentrations f o r the waters from the flooded K West Basin canisters range from <0.2 t o 488 pg/ml (mean 45.8).'…”

“…After flooding, the canister was set aside f o r eight or more hours t o allow the barrel l i q u i d reach equilibrium with the flood water via thermal mixing (Trimble 1996a) . During the second sampling and characterization campaign f o r the K West basin canisters, the l i q u i d sampling was completed 24 o r more hours a f t e r flooding (Trimble 1997b). Trimble estimated t h a t t h i s increased the water i n the canister by 10 t o 16%.…”
