I December 13, 1999 • • Page 9 ' monitoring well, was also re-completed to become a B Groove well (29-2B). Three new alluvial monitoring wells (19-3, 21-5, and 28-1) were also constructed. ' In summary, the 25 well completions at the Piceance Site include three Dissolution Surface I completions, six B Groove completions, six A Groove completions, six Uinta completions, and four alluvial completions. Monitoring of the water supply well 20-8 (Uinta Formation) for water I quality provides monitoring of changing conditions resulting from operation of the test facility. Table 1 includes a complete list of the Piceance Site wells. I 2.1.1 Parnc/lute Sile Groundwater Monitoring Locations American Soda will use at least one monitoring well to monitor groundwater quality and I water level at the Parachute processing site. The monitoring well will be completed at the base of the Alluvial Aquifer to monitor for potential leakage from the process pond system. The I monitoring well will be situated down-gradient of the proposed pond, between the pond system and Parachute Creek. I 2.1.3 Local Domestic Wel! Locations Domestic wells included in this Water Monitoring Plan are two wells located along I Piceance Creek, between the mouth of Horse Draw and the north edge of Section 15.One of the domestic wells will be Horse Draw Well (formerly USBM O1 A) located near the abandoned Horse Draw shaft, and the other will be Burke's Well, located downstream of the Yankee Gulch site. 2.2 Groundwater Monitoring Program Groundwater monitoring will consist ofwater-level measurement and water-quality sample collection and analysis. The sampling frequencies, sampling methods, and water-quality parameters aze provided in this section. As described in Section 1.0, the groundwater monitoring program is divided into two periods, a baseline period and the first 5 years of commercial operations (operations period). The baseline data collection period includes monthly sampling during 5 quarters preceding the startup of commercial operations as specified by the CDMG. 2.2.1 Water-Level Monitoring Water level monitoring in all groundwater wells will be performed in accordance with the procedures presented in Appendix B or in accordance with manufacturer's recommendation, where automated water-level equipment is used.
