' Deccmher 23, 1999 Pul,~c l0 1 1 t~;~,,,..,, ,, c..,, During the baseline period, groundwater levels will be measured monthly for all monitoring well completions. This will include wells located in and out of the 0-5 year mining panel. During the first 5 years of commercial operations, water levels will be measured monthly for all monitoring wells completed in zones above the Dissolution Surface (including in-panel and out-ol=panel wells), and weekly (or monitoring wells completed at the Dissolution Surface. The weekly water-level measurements for Dissolution Surface monitoring wells will be performed using suitable automated data recording equipment. The automated equipment will not be ' installed until the beginning of commercial operations. Pnt•uchulc Silc Once the alluvial monitoring well is constructed at the Parachute Site, water level will be measured on a monthly basis. Water-level monitoring will be conducted in accordance with the procedures detailed in Appendix 4. Domestic Hoc//.r Water levels will be measured in the available domestic wells contained in this Water Monitoring Plan on a monthly basis, and will be performed in accordance with the procedures ' detailed in Appendix Q. 2.2.1 Grnrutrhan/er Qtrnliry Mrurimriag ' Groundwater quality will be monitored at the Piceance Si[e, the Parachute Site, and in domestic water wells. This section includes details regarding water-quality parameters to be ' measured in water samples, groundwater quality monitoring schedules, and groundwater monitoring procedures. Gr•oundwnler Uunlit}~ Purnmelc~r•s The monitoring schedule allows for water quality samples to be analyzed for either the ' standard list of parameters contained in WQI (Table 2) or the comprehensive list of parameters contained in WQ2 (Table 3). In general, water quality samples will be analyzed for the WQ2 ' parameters on a less frequent basis that the WQI parameters. The two lists of parameters were developed in consultation with the BLM, GPA, CDMG, USGS, Rio 131anco County, and American ' Soda. These parameters are generally in accordance with applicable water-quality parameters listed in the Colorndo Deparunent of Public Health and Cnvironment (CDPHG), Water Quality 1 ' Agapito Associates, Inc.
