For each sample, one 8-ounce glass jar will be collected for each laboratory. The samples will <br /> be chilled to 4°C immediately upon collection. <br /> CLPAS Metals. Sediment samples to be analyzed for CLPAS metals and chromium VI will be <br /> homogenized and transferred from the sample-dedicated homogenization pail into 8-ounce, <br /> wide-mouth glass jars. For each sample, one 8-ounce glass jar will be collected for each <br /> laboratory. The samples will be chilled to 4°C immediately upon collection. A laboratory to be <br /> determined by EPA will also analyze the sediment samples for Chromium V1. The holding time <br /> for chromium VI in sediment is 6 months. <br /> 8.2.3 Wood Samples <br /> Low concentration wood samples to be analyzed for CLPAS semi-volatile organic compounds, <br /> pulverized (if possible) and transferred into 8-ounce, wide-mouth glass jars. No preservative is <br /> required for these samples. The samples will be chilled to 4°C immediately upon collection. <br /> 8.2.4 Groundwater Samples <br /> Low concentration groundwater samples to be analyzed for CLPAS Pesticides, CLPAS <br /> Semivolatile Organic Compounds will be collected in I-liter amber glass bottles. No preservative <br /> is required for these samples. The samples will be chilled to 4°C immediately upon collection. <br /> Two bottles of each groundwater sample are required for each laboratory. <br /> RAP Volatile Organic Compounds plus MTBE and RAP TPH as Gasoline. Low concentration <br /> groundwater samples to be analyzed for RAP volatile organic compounds will be collected in <br /> pre-preserved 40-m1 glass vials containing 1:1 hydrochloric acid (HCl). The vials will be filled <br /> so that no headspace occurs. The samples will be chilled to 4°C immediately upon collection. <br /> Three vials of each groundwater sample is required for each laboratory. <br /> CLPAS Metals. Low concentration groundwater samples collected for CLPAS metals analysis <br /> will be collected in 1-liter polyethylene bottles with nitric acid (HNO3). The samples will be <br /> chilled to 4°C immediately upon collection. One bottle of each groundwater sample is required <br /> for each laboratory. <br /> 8.2.5 Field Blanks <br /> RAP Volatile Organic Compounds plus MTBE and RAP TPH as Gasoline. Low concentration <br /> trip blanks to be analyzed for volatile organic compounds and TPH as gasoline will be collected <br /> in 40-m1 glass vials pre-preserved with 1:1 hydrochloric acid (HCl). The vials will be filled so <br /> that no headspace occurs. The samples will be chilled to 4°C immediately upon collection. <br /> Three vials of each trip blank are required for each laboratory. <br /> Low concentration groundwater samples to be analyzed for CLPAS Pesticides, CLPAS <br /> Semivolatile Organic Compounds will be collected in 1-liter amber glass bottles.
