rather for Vic?
Is it possible that a small amount of free product could be in the samples? Also, it seems to me that it could be possible that the solubility is different because of the other chemicals present. However, I would have expected the solubility to decrease, not increase, because of Raoult’s Law for mixtures. Solubility values reported in the literature vary quite a bit for some chemicals. I used the EPA’s Soil Screening Guidance (SSG) for the default solubility values in RISC. This is a fairly recent, “peer-reviewed” source and many of the States here are using the chemical values from this document as defaults in their RBCA programs. (I’m not sure it is the best source however.
