3.3.2 Calcium
• Calcium concentrations have not shown an identifiable increase or decrease in concentrations over the 2007 sampling period.
The baseline level for CRMW09 and CRMW16 was not established in the WOBR because only two samples were reported at
that time. Three additional samples are reported from December 2006 through October 2007 for these two wells. The
baseline levels for these two wells have been updated using this additional data.
CRMW09 calcium concentration is higher than any of the other wells tested as shown below.
The baseline level for CRMW01 has also been adjusted to reflect data collected from October 2005 through October 2007
since no mining activities have taken place in the area of this well.
