• 4.8.5.2 Ground-Water Monitoring <br />Map M52 shows the locations of the ground-water monttoring sites. The current list of ground-water <br />parameters to be monitored is given in Table 4.8-13. The current ground-water monttoring schedule is <br />summarized in Table 4.8-13a. Table 4.8-13a was changed in PR-3 (penntt term 1993-1997) in order to <br />accommodate a more dearly understandable and user friendly monttoring schedule format. <br />Four lists of ground-water parameters are sampled as outlined in Table 4.8-13, according to the schedule <br />presented in Table 4.8-13a. The hydrologic data derived from this monttoring program is submitted to the <br />Division on an annual basis by March 15 of each year. The first report was submitted to the Division in <br />January, 1983. Appendix W is updated to contain each annual report. <br />List B in Table 4.8-13 gives the parameters to lx: sampled on an annual basis. LIST C is used to <br />quarterly or semiannually sample operational wells which monttor the effects of mining in alas nd <br />associated wtth uliltty wastes disposal. LIST D is used for wells which quarterly monitor the effects of <br />utiltty wastes disposal. Wdh regard to List D, actual installation of wells in the backfilled pits will be <br />dependent upon whether or not utility wastes are disposed upgradient from the proposed monitoring <br />sttes. Proposed wells in the undisturbed aquifers downgredient of utility wastes disposal sites will be <br />installed as waste disposal progresses and as needed. List E is used for monitoring the LUX-1 well. The <br />• LUX-1 well is monitored in order to document any changes to the Lux drinking water well that might occur <br />as a result of mining impacts. <br />Historical information on well completion information and Itthologic logs for monitoring wells are included <br />in various sections of the perntt application. Appendix H, Radian Report Tech. Note 280.311-02-03 I'rsts <br />information for monttoring well series GF, GBB, and GZ. Section 2.7.7.3 (p 2-539) of the perntt <br />application provides information on Itthologic logs for monitoring wells F-1, F-2, P-1, P-3, P-5, and P-8. A <br />well construction diagram is provided in Appendix V. Appendix V also provides Itthologic logs and <br />monttoring well completion information for wells GA-1, GA-2, G&1, GB-2, GB-5, GC-1, GC-3, GE-1, <br />GE-2, GE-3, GD-1, GD-1(2), and Empire Well 81-03A. <br />"Mercury;'silver and zinc are not inducted in LIST B because"their concentrations in historic samples were • ~" <br />vary low and because tt is unlikely they would occur in significant concentrations in any potential leachate <br />from utility wastes (refer to Section 4.3.4.8). Iron was removed from List C as the definttion of variations <br />in iron concerrtrations is not very useful since the range in this parameter has been defined. TDS was <br />added to List C until a good correlation between TDS and condudivtty can be established. Carbonate <br />was added to list B and is used for sttuations when the pH is greater than 8.3. <br />a-za2 pe-~ <br />_ MAY. _1 3 _1998 <br />
