Spoil Water Quality <br />1. Three wells are referenced on page 1 of the report. Water <br />level and water. quality data from SP-1 and SP-2 are given in <br />Appendix III of this report. The SP-3 well has been dry since <br />construction. Completion information for all three wells are <br />also given in Appendix III. <br />2. The impacts of elevated levels of certain chemical parameters <br />in spoil discharges is discussed in more detail in the final <br />backfill report. However not all parameters have been evaluated <br />due to the analytical procedures used in determining concentra- <br />tions after various parameters, i.e. comparing dissolved and <br />total recoverable concentrations. <br />3. The problem of stream standards being set lower than the <br />detection levels of laboratory procedures for certain parameters <br />has been discussed with the Colorado Department of Health (CDOH) <br />on several occasions. We have attached a letter from ACZ <br />Bookcliffs laboratories concerning this issue in Appendix IV. <br />u <br />4. Accepted methods of sample collection and preservation • <br />were followed in the collection of water quality data. All <br />samples taken for dissolved constituents were filtered. <br />5. An explanation of the spoil discharge projections is given <br />in the response to comment 4 in the Spoil Aquifer Characteristics <br />section. <br />6. The suggested formatting changes have been included in <br />the final report. <br />7. Salt loading calculations have been performed for the low <br />flow irrigation period and are discussed in the final report. <br />• <br />
