Due to combustible considerations the samples prepared for TCLP
were ground-at-Steck prior to submittal to the contracted
laboratory.
Samples L5 and L9 (Type 2 and Type 4) were spiked with cobalt,
cesium, and strontium. Then casted into 1.5" by 2" cylinders.
An exotherm profile on the prepared samples was obtain.
November 16. 1992
The leachability study was started for surrogate waste Types 2
and 4. The following time points have been pulled:
30 seconds,
2 hour,
5 hour,
-24_hnur,
2 day,
3 day,
4 day, and
5 day.
The 90 day sample will be pulled on February 15, 1993. An
amendment to the original report will follow within a week of
the 90 day leach interval for TYPE 2 and TYPE 4 surrogate waste
streams.
All time points up to and including 5 days have been assayed.
Leachability calculations are in progress.
Samples of surrogate wastes TYPE a. and-TYPE-1_were-successfully
solidified in the alternate polymer, exotherm data was
recorded. The formulations are identical to the one used for
the sample preparation for all the testing. I also have done
an exotherm profile on TYPE 4 surrogate waste.
November 23, 1992
TCLP extraction was started on L3, L5, L7 and L9 samples. The
samples will be assayed for their metals.
