SAMPLING AND ANALYSIS, QUALITY ASSURANCE AND QUALITY CONTROL Sample Clauses

SAMPLING AND ANALYSIS, QUALITY ASSURANCE AND QUALITY CONTROL. ‌ A summary table of sampling, analysis, and data collection is presented below in Table 4. A listing of Northwest Plume monitoring ▇▇▇▇▇ that are not associated with water policy boundary monitoring are presented in Table 5. Sample point(s) Parameters Frequencya Decision rule (refer to Table 3) (EW230 and EW231 if returned to service) Monitoring ▇▇▇▇▇ (refer to Pump Rates Daily #6 Water Levels Weekly #6 TCE, 99Tc, Gross Alpha/Beta Quarterly #6 Table 5) TCE, 99Tc Semiannually #1 Water Policy Boundary Monitoring ▇▇▇▇▇ (MW106A, MW134, MW146, MW194, MW201, MW202, MW426, MW427, MW432, MW433, MW435, MW441, MW452, R2, R13, R26, R53, and R245) TCE, 99Tc 99Tc Monthly #5, #6 Si, Fe, Mn, VOCs Quarterlyb NA Calcium hardness Quarterly NA Sulfates, Alkalinity Semiannually NA System effluent (HV-171) TCE Weekly #2, #3, #4 99Tc Weekly #2, #5 Air stripper effluent (HV-014) 99Tc Monthlyb #5 System ion exchange units 99Tc Monthlyc N/A Operational data Multipled Daily and weekly #6, #7 a Frequency definitions are as follows: Daily—one sample per day excluding weekends and holidays. Weekly—one sample per calendar week. Bimonthly—two samples per calendar month. Monthly—one sample per calendar month. Quarterly—one sample every 3 months, with samples no more than 4 months apart. Semiannual—two samples each fiscal year Annually—one sample each fiscal year no less than 3 months apart. b This sample must be taken on the same date and approximate time as the monthly system influent sample (HV-082). c Samples will be collected from each lead column (two columns are in the lead position). The 99Tc data generated will be used to forecast and determine breakthrough of the ion exchange resin. d Operational data collection parameters include pressure, flow rates, tank levels, and others. For details, refer to procedure CP4-ER-0017, Northwest/Northeast Plume Daily Operational Data Collection and Maintenance. This procedure can be found in the procedures folder on the Public Documents website (▇▇▇▇▇://▇▇▇▇▇▇▇.▇▇▇.▇▇▇▇.▇▇▇/).
