A new Terra-CoreTM <br /> plunger will be used for each sampling station. <br /> The brass or stainless-steel tube will be then capped with TeflonTM squares and end caps <br /> and submitted to the analytical laboratory for analysis of TPHd. <br /> Sample container requirements, holding times, and preservation requirements are <br /> outlined in Table 2. <br /> Each sample will be labeled following procedures described in Section 3.2.4.2. Samples <br /> will be stored in an ice-cooled chest and maintained at approximately 0 to 6 degrees <br /> Celsius (°C) for transport under chain-of-custody procedures (Section 3.2.4.3) to a <br /> certified laboratory for analysis of VOCs and TPHg using USEPA Method 8260B and <br /> TPHd using USEPA Method 8015B. Analytical methods and expected reporting limits <br /> for each parameter are included in Table 3. <br /> The laboratory will be responsible for the following: <br /> • Analyze the samples following USEPA methods and laboratory standard <br /> operating procedures; <br /> • Follow documentation and custody procedures; <br /> • Meet all reporting limit requirements; <br /> 20190122- FINAL UST Data Gap Work Plan 8 22.01.2019 <br />
