Reclamation of Piezometer Wells (2) <br />Two water sampling wells were installed into the Level 6 waste rock pile as part of the ongoing <br />hydrologic evaluation of the site setting. The specifications of the wells are summarized in <br />Table B.2. The `Well Construction and Test Reports' for each well are provided in `Monitoring <br />Well Report B, and Monitoring Well Report C' documents; which were provided to the <br />Colorado Division of Water Resources as part of the monitoring well permit compliance. These <br />wells will be used for groundwater saml-pling through the duration of the mining activity, as they <br />represent measures of groundwater level and quality within and adjacent to the waste rock pile. <br />Well `B' traverses a shallow lens of waste rock, and approximately 100 feet of underlying <br />alluvium. Well `C' is almost entirely within the waste rock profile, with about 2' of contact into <br />the underlying alluvium. Well `B' therefore represents the feature of highest concern in regards <br />to reclamation, since it represents a possible conduit to the native alluvium. Both wells are <br />currently steel-capped and cased with lacking caps. <br />Well C is entirely encompassed within the waste rock pile. It will be reclaimed by being <br />removed as part of the waste rock removal. Well B provides a conduit into the underlying <br />alluvium, therefore it will be reclaimed by being grout-sealed/plugged at the alluvium level. The <br />upper portion of the pipe that occurs within the waste rock pile, will be cut off and removed as <br />part of the waste rock removal program. <br />6
