• No new maximum or minimum values were recorded at we11009-5-10 (Table 24). At we11001-5-5 (Table 25) a new minimum value for laboratory ph was recorded, and a new maximum value for sulfate. At well 008-AV-2 (Table 26) no new minimum or maximum values were recorded. At well FO-1 (Table 28) new minimum values were recorded for dissolved calcium, dissolved magnesium, dissolved sodium, and dissolved manganese. At well FO-4 (Table 29) no new maximum or minimum values were recorded. Wells FO-1 and FO-4 exhibit field conductivities notably higher than alluvial wells upstream and downstream of these sites. Well FO-1 is chazacterizzd with calcium and sulfate as the dominant cation and anion respectively. Well FO-4 exhibits sodium and sulfate as the dominant ions. Fish Creek Alluvial Groundwater: Diving 2001 five Fish Creek alluvial wells (006-AY-1, 006-AZ-3, 006- t ~ AW-2, 008-AU-3 and 008-AW-3) required monitoring for water levels and field parameters on a monthly basis, and water quality sampling on a quarterly basis. Note that well 006-AW-2 went dry during the last quarter of 2001 and was not sampled for water quality during this period. All other sampling requirements were met. Tables 30 through 34 provide summaries of the 2001 Water Yeaz data collected at each site. Tables 30a through 34a provide period of record statistical summaries of collected data at each site. Figures 56 through 65 provide gaphical representations of water levels and selected water quality parameters recorded at each site. Two new alluvial we1Ls (AVF-13 and AVF-14) were installed in August 2001. These wells will require monitoring for water levels and field pazameters on a quarterly basis, and water quality sampling on a semi- annual basis. The August installation date allowed one round of water quahty sampling from these wells before • the end of the 2001 water year. Data for new sites AVF-13 and AVF-14 are provided in Tables 77 and 78, respectively. Figures 136 through 139 provide gaphical representations of water levels and selected water quality pazameters recorded at each site. Due to the limited period in which these wells have been established, the data base will need to be expanded before maximum and minimum values can be evaluated. None of the values recorded during the initial sampling episode fell outside the typical historical range of other wells in this aquifer. Water levels at well 006-AY-1, located on Fish Creek upstream of the Southwest Mining District and Mine 2, had exhibited a relatively steady increase from approximately 1990 through 1994 (see Figure 56). From 1994 through 1997, that trend has reversed and is generally decreasing from 1994 through 2001. The maximum fluctuation in water level at this site over the period of record is 7.5' to date. Well 006-ALr3 is situated downstream of 006-AY-1 and below the Fish Creek Borehole. We11006-A~3 is monitored in conjunction with surface water site 307 and the water level relationship is presented as Figure 58. Further downstream, well 006- AW-2 and surface water site 1002 are monitored and water levels are plotted as Figure 60. Again in 2001, the interrelationship between alluvial groundwater and surface water is evident on these two plots. Well 008-AU-3 and surface water site 305 monitor water levels upstream from the Fish Creek Tipple azea with data presented on Figure 62. The furthest downgradient Fish Creek alluvial monitoring well is 008-AW-3 (Figure 64) located neaz the Fish Creek Tipple. No unusual water level fluctuations were noted at arty of these sites during 2001. • Elevated ammonia readings in the Fish Creek Alluvium, fast detected in August of 1995, were sustained through 2001. Additionally, at well 006-AY-1 (Table 30) a new minimum value was recorded dissolved sodium. At well 8
