<br />Review of CC&V Response to Commitment No. 36 <br />Memo to B. Keffelew, June 27, 1994 <br />Page 5 <br /> <br />compliance points. The degree to which the data overestimate what will actually be present in <br />the environment needs to be quantified. <br />CONCLUSIONS <br />In order to proceed with constnrction of the underdrain using the materials that were tested, <br />CC&V should complete the following. <br />1. Re-analyze samples for missing metals (for drinking water), and hardness (for surface <br />water), or demonstrate that groundwater will not be affected by recharge from An;qua <br />Gulch water that will flow through the underdrain. <br />2. Provide to the Division a list of all classified surface and groundwater uses, an <br />accompanying list of all regulated parameters, and list of applicable standards. <br />3. Re-test for mercury and silver, using appropriate detection limits, or provide a model of <br />the results showing that the standards will not be exceeded. <br />4. Provided any of the groundwater (i.e. drinking water) parameters require lower limits <br />of analytical detection than those quoted for surface water, those parameters should be <br />re-analyzed using the appropriate standards, or a model of the results showing that the <br />standards will not be exceeded should be supplied to the Division. <br />cc: Bruce Humphries <br />Jim Pendleton <br />Carl Mount <br />Bill York-Feirn <br />Attachment <br />M: \MIN\HHP\CC&VCM36.
