• Field parameter measurements obtained in 1996 from the Fish Creek alluvia! wells remained within previously <br />established ranges with the exception of pH measwements recorded in July at wells 006-AY-1 and 006-AZ-3. <br />Subsequent measwements returned to typical readings. New minimum field temperatures were recorded at wells <br />006-AW-2 and 008 AU-3 in February with 006-AW-2 noted as frozen in March. Field conductivities and TDS <br />values are observed in general to increase in the downstream direction along Fish Creek. Well 008-AU-3 is the <br />exception to this rule. The highest levels are noted to occur in association with wells 006-AW-2 and 008-AW-3. <br />The Fish Creek Borehole impacts as measured at well 006-AZ-3 ap/p~ear moderate relative to the additional /~ <br />increases downstream. ,/y)~~ Z ~.i~ Sph~ S ? v.ZU~O~~ C~'-?~`~S CLLR ~'~t'~~) <br />Other monitored water quality parameters retumed values at the Fish Creek alluvial wells typically within <br />previously established ranges during 1996. Exceptions include a new minimum dissolved sodium concentration <br />recorded at well 006-AY-1 in March, and new maximum nitrate and nitrate/nitrite as N values documented in <br />May (Table 26), Well 006-AZ-3 retumed new maximum calcium levels in November, March, and August, new <br />maximum hardness levels in November and August, new minimum SAR values in March and August, a new <br />maximum ortho-dissolved phosphorus value in May, and new maximum total alkalinity, ammonia, lab <br />conductivity, and nitrite values in August. Elevated ammonia readings first detected in August of 1995 were <br />sustained throughout 1996. Lastly, TDS values beyond the previously established maximum were recorded in <br />• November. March, and August (Table 27). Anew maximum dissolved manganese value was recorded in <br />November at Well 008-A W-3. <br />TroutEreek Alluvial 6roundwater:_During 1996, one Trout Creek alluvial monitoring well (008-AT-1}required <br />monitoring for water levels and field parameters on a monthly basis, and water quality sampling on a quarterly <br />basis. All monitoring requirements were met at this site. Table 31 provides a summary of the 1996 Water Year <br />data collected. Figures 58 and 59 provide graphical representations of water level and field conductivity <br />information to date. One additional well (Jones) required monitoring for water levels and field parameters on a <br />quarterly basis, and water quality sampling for full suite pazameters on an annual basis and sulfate on a quarterly <br />basis. Table 32 provides the 1996 data for this well with Figures 60 and 61 providing graphical representations of <br />selected data. <br />Well 008-AT-1 is monitored in conjunction with surface water site 1005, Figure 58 depicts the water level <br />relationship between these two sites. Water quality parameter values depicted on Table 3 i are comparable to <br />other monitored alluvial wells located upstream on both Foidel Creek and Fish Creek. <br />Middle Cieek-Alluvial Gioun`d"water: Two Middle Creek alluvial wells were incorporated into the monitoring <br />network during 1996. Both will require monthly monitoring of water levels and field parameters with quarterly <br />water quality sampling. Wells AVM-] and AVM-2 are located on the Middle Creek drainage. AVM-1 lies <br />approximately 3500' upstream of the confluence of Middle and Foidel Creeks. AVM-2 lies approximately 7500' <br />-8- <br />
