1. Most recent results show the pH in the WCL solution to be ~ 7.7
2. ClO4- was not the dominant anion in solution. Most recent results show that SO4= and HCO3- dominate at 2-3x the ClO4-.
3. The fact the no organics were detected by TEGA can be attributed to the presence of 0.6 % ClO4- in the soil, which would most likely oxidize any organics as the TEGA temperature was ramped above 200C.
