The parameters silver, cyanide, copper, mercury, and nitrate as N (dissolved) were not
included in this list since either the standards are less than the diction limit or no analyses
of these constituents were above the detection limits. Likewise lead (dissolved),
• selenium (dissolved), and zinc (dissolved) have been removed from the list.
The site SPJC-1 has been inactivated because discharge from Coal Bed Methane Wells
has made it impossible to ide~ify and isolate flow that maybe issuing from this site.
Stock Ponds
•
Stock ponds designated for annual water level monitoring are identified in Table 2.05.6-
13. Water quality monitoring is not proposed as water quality impacts are not
anticipated. Since installation of CBM Wells upstream from the stock pond, flow to the
pond and thus water quality and water levels are more directly the result of water issuing
from these wells than fiom natural surface and ground water flows. With final
reclamation in progress, monitoring of stock ponds is terminated.
