An evaluation of the stability of synthetic Grande Ronde groundwater formulations GR-3 and GR-4
Simple solubility calculations indicate that synthetic Grande Ronde groundwater formulations GR-3 and GR-4 may be unstable with respect to the precipitation of certain components. The validity of calculations of this type is, however, limited by the complexity of the solutions. To address the chemical stability of these formulations properly, an experimental evaluation was performed. The evaluation revealed that GR-3 and GR-4 were similar in their chemical stability. Both were found to be quite stable with respect to all constituents, except silicate and inorganic carbon, over a 30-d period. Some instability of monomeric silicate was observed. However, this did not result in a concentration change of greater than 5%, and no evidence of particulate formation was observed. Both formulations were found to be relatively unstable with respect to inorganic carbon concentration. A general trend toward increasing carbon concentration was observed. This was attributed to absorption of CO/sub 2/ from the atmosphere. Storing the synthetic groundwater in sealed containers eliminated this problem. 5 refs., 24 tabs.
