SAMPLING, ANALYSIS, AND DATA COLLECTION Clause Samples

SAMPLING, ANALYSIS, AND DATA COLLECTION. To ensure that all DQOs are met, a summary table of sampling, analysis, and data collection was formulated and is presented in Table 6. Figure 4 identifies the location of treatment system components and physical sample locations for the Northeast Plume Optimization Project. The air stripper effluent sample point for performance monitoring of TCE removal efficiency is in the same general location inside both the C-765 (servicing EW234 and shown in Figure 4) and C-765-A (servicing EW235) TUs. Figure 4 identifies that CERCLA Outfall 001 is the sample collection point for compliance with ARARs that occurs prior to comingling with other waters. Refer to Section 6 and Figures 6 and 7 of the RAWP for additional information (DOE 2018a).
