• RESULTS -SPRINGS FOR 1995 WATER YEAR
Two springs were sampled during the 1995 water year. The springs sampled were
REA SPG #3 and CJ-LO-SPG #4. Both springs originate below the mine and permit
area. REA SPG #3 is approximately 1,000 feet south of the permit area in REA
Canyon. CJ-LO-SPG #4 is approximately 200 feet west of the permit area in Cazbon
Junction Canyon. Overall, the springs sampled from the third quarter of 1994 through
the third quarter of 1995 showed typical flow rates that were higher in early spring and
summer and lower in the fall and winter. REA SPG #3 has a characteristically higher
level of calcium than does CJ-LO-SPG #4. This higher level of calcium does not
appeaz to be related to any other elements sampled. Trace element levels were
consistent throughout the sampling period.
RESULTS -WELLS FOR 1995 WATER YEAR
Four wells were sampled during the 1995 sampling period. The wells sampled were
designated 17-B, 10-B, 94-1, and 11-B. Ground water data for the four wells sampled
for the 1995 water year shows consistent data within each quarter for each well. Depth
to water remained the same for each well during the sampling period. Concentration
levels for trace metals did not fluctuate for any of the wells for the four periods
sampled. Some wells are characteristically different in nature than others. Wells 10-B
• and 94-1 have naturally occurring levels of calcium and bicarbonate tfiat aze higher than
wells 11-B and 17-B. Carbonate is only apparent in the samples for wells 10-B, 11-B,
and l7-B periodically during the third and fourth quarters of the year. Sulfate levels
are naturally higher in wells 10-B and 94-1 than in wells 11-B and 17-B. Total
dissolved solids are greater in wells 94-1 and 10-B.
RESULTS - SPRING WATER DATA FROM 1982 THROUGH 1995
Spring flow patterns are consistent throughout most of the data collection period. The
notable peaks in spring flow occur in the second quarters of 1986, 1987, 1994, and
1995. During these years flows were typically higher in spring and early summer and
typically lower during the fall and winter. This scenario of higher flows in spring and
early summer and lower flows in fall and winter is typical of surface water dependent
on snow melt and winter precipitation for rechazge.
Overall, trace metals were consistently present in low concentrations throughout the
sampling period. These consistent levels of trace metals indicates that there has been
no change in concentration levels due to mining from the site.
Temperature of the springs is higher in the summer and lower in the winter. This
change in temperature is natural, and reflects warming neaz the surface. This change in
. temperature does not reflect any unusual spring wnditions.
