The groundwater geochemistry of the Snake River Plain aquifer system has been described by Wood and Low (1988). It is an excellent example of how a knowledge of aquifer mineralogy can...

The Snake River Plain aquifer is also an example of an aquifer in which groundwater chemistry is not strongly affected by directions and rates of groundwater flow. There are no well-defined changes in solute concentrations along the aquifer flow path (Table 1). As we shall see in subsequent examples, this insensitivity to directions of groundwater flow is unusual, and is due to the relatively rapid nature of ongoing dissolution and precipitation reactions in the Snake River Plain aquifer.

Figure 3. Mean urea hydrolysis rates for Snake River Plain Aquifer groundwater consortia provided with 0 (GW), 0.01%, 0.001%, and 0.00075% molasses as a carbon source supplement along with 5.9 nmol C-urea. For comparison, mean urea hydrolysis rates are also shown for B. pasteurii, E. coli, and filtered groundwater, all with 0.001% molasses. Each treatment was performed in triplicate, and error bars depict the standard deviation.
