Water level data is summarized in the last section of the ground water monitoring report. In
addition to the standard water level data provided for each sampling point, there are two tables
provided representing date obtained from probes which are pressure transducers submerged
just below the water level at the top of each well with continuous hourly readings collected in a
data recorder. Dissolution surface monitoring Well 29-4D and Well 21~DX are both equipped
with these continuous water level probes. The variations in level data recorded during this one
month time increment is very small, only ranging about one foot from minimum to maximum
level for either well. American Soda will continue to test the reliability of the probes in each of
these wells throughout the next monitoring period.
American Soda is required to sample well field injection and production streams for water quality
chemical constituents on a monthly frequency for the first six months of operation. Production
stream samples were collected during each month of the second operational quarter. This data
is provided to you as a separate attachment and is marked as Confidential Business
Information.
Should you have any questions or comments regarding this information, please contact me at
