Therefore, <br />all recorded monitoring events are considered Operational. <br />'Not Enough Water for Parameters <br />Borehole B -7, also referred to as Node 22, is located below sedimentation pond #4 and is periodically monitored for <br />water quality to ascertain potential groundwater contamination attributable to the East Mine facilities area. <br />There is no baseline collection possible for points initiated after the influence of mining. <br />Figure Number 3 <br />
