The <br />water quality data show consistency with previous operational and baseline data. The results of <br />the water quality and quantity analyses also demonstrate that the concentrations of chemical <br />pazameters were well within the acceptable limits. However, due to the very dry yeaz, many sites <br />were dry so only limited water sampling could be run. The Division has the following questions <br />and comments: <br />1. There are several wells that do not appear to have the required full suite analyses. For <br />instance, according to Table 1 of the 2002 AHR, the SM series of wells aze required to <br />have semi-annual full suite analyses. However, the 2002 AHR data sheets show that only <br />an annual full suite analysis was run. Also, according to Table 1, wells MW-1 and MW-3 <br />require quarterly full suite analyses. However, MW-1 has no fourth quarter and MW-3 <br />has no first and fourth quarter full suite analyses. Please explain. If the reason is that there <br />was not enough water for such analyses, please state that in the field comments for each <br />sampling event. <br />2. Two springs, S3100 and S3200, were sampled for full suite analyses on a semi-annual <br />basis. However, Table 1 shows that full suite analyses need to be run on a quarterly basis. <br />Please explain. <br />Office of Office of Colorado <br />Mined Land Reclamation Active and Inactive Mines Geological Survey <br />
