2 Report soil sample results on a dry-weight basis in micrograms per kilogram (Fg/kg). Report percent solid and percent moisture to the nearest whole percentage point. For rounding results, adhere to the following rules: a)If the number following those to be retained is less than 5, round down; b)If the number following those to be retained is greater than 5, round up; or c)If the number following the last digit to be retained is equal to 5, round down if the digit is even, or round up if the digit is odd. All records of analysis and calculations must be legible and sufficient to recalculate all sample concentrations and QC results. Include an example calculation in the data package. 8270 CRF 1 of 5 Revision 12/07/1999 Table 1B: Target compound List and Contract Required Quantitation Limits (CRQLs) for SEMIVOLATILE ORGANIC COMPOUNDS (SVOCs) by SW-846 Method 8270 Contract RequiredQuantitation Limits PRGs Analyte Water (Fg/L) Soil (mg/kg) Industrial Soil (mg/kg) TapWater (Fg/L) 1,2-Dichlorobenzene 10 370 370 1,2,4-Trichlorobenzene 10 1,700 190 1,3-Dichlorobenzene 10 140 180 1,4-Dichlorobenzene 10 2-Chloronaphthalene 10 NA NA 2-Chlorophenol 10 240 38 2-Methylnaphthalene 10 NA NA 2-Methylphenol 10 53,000 1,800 2-Nitroaniline 25 64 2-Nitrophenol 10 NA NA 2,2 -oxybis (1-Chloropropane)
