• Field parameter measurements obtained in 1996 from the Fish Creek alluvial wells remained within previously <br />established ranges with the exception of pH measurements recorded in July at wells 006-AY-I and 006-AZ-3. <br />Subsequent measurements returned [o 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 downsyeam direction alon 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-A W-2 and 008-A W-3. <br />The Fish Creek Borehole impacts as measured at well 006-AZ-3 appear moderate relative to the additionalt^ <br />increases downstream. ,/yl~~ z ~t1 S,Or~'•-~5? ~.20~09y ri5 <L~fs v~~) <br />Other monitored water quality parameters returned values at the Fish Creek alluvial wells typically within <br />previously established ranges during 1996. Exceptions include a new minimum dissolved sodiwn concentration <br />recorded at well 006-AY-I in March, and new maximum nivate and nitrate/nitrite as N values documented in <br />May ("fable 26). Well 006-AZ-3 returned 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 />mariinwn ortlto-dissolved phosphorus value in May, and new maximum total alkalinity, ammonia lab <br />conductivit}~, and nitrite values in August. Elevated ammonia readings first detected in August of 1995 were <br />sustained throughout 1996. Lastly, TDS values beyond [he previously established maximum were recorded in <br />• November, Marclt, and August (Table 27). Anew maximum dissolved manganese value was recorded in <br />Noveinberat We11008-AW-3. <br />Trout Creek Alluvial Groundwater During 1996, one Trout Creek alluvial monitoring well (008-AT-I) 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 parameters 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 [he water level <br />relationship between these two sites. Water quality parameter values depicted on Table 31 are comparable to <br />outer monitored alluvial wells located upsveam on both Foidel Creek and Fish Creek. <br />Middle Creek Alluvial Groundwater: 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-I and AVM-2 are located on the Middle Creek drainage. AVM-I lies <br />• appro.imately 3500' upstream of the confluence of Middle and Foidel Creeks. AVM-2 lies approximately 7500' <br />-8- <br />
