Temp. -Temperature in degrees F recovered at the pregnant liquor tank. Assay - g/I sodium chloride or sodium bicarbonate in the composite recovery liquor as total bicarbonate. (Total bicarbonate =bicarbonate g/I + 1.58 x carbonate g/I). Tons - total monthly bicarbonate production without adjustments per cavity. Figure 4-2 illustrates the 2005 pregnant liquor results and Figure 4-3 represents monthly production for 2005 as shown in actual project activities (Section 3.1.2). Production and processing were performed for twelve months of the year. The production was shared between cavities #1 A, 5H, and 6H for the year of 2005. Good brine grade and temperatures were noted throughout the year. The increase in sodium chloride was associated with 5H cavity. The balance between injection and recovery rates for cavities 1A, 5H, and 6H has been continuously monitored using fluid level indicators (pressure transmitters) installed in existing Dissolution Surface aquifer monitoring wells located near the active cavities. la-
