Preparation Note

The PT sample size provide is 33 g of soil. The soil has been chemically stabilized with 6 mL of methanol to minimize degradation of the sample. The PT sample has been sized to 100 mesh. Required storage condition is 4o C. The sample has been intentionally prepared with an apparent headspace. The sample was fortified with a blended gasoline from three different refineries located in the Mountain West. This sample can be analyzed by methods including but not limited to MA VPH, EPA 8015M, NWTPH Gx, and IOWA OA-1.

Sample Preparation
The 25 g soil PT sample is preserved in 25 mL methanol.
Mix and sample the soil at 4° C to minimize volatilization of the contents.
The sample is a soil containing gasoline range organics (GRO) to be extracted and analyzed using the MA VPH method.
On the report form, list the extraction technique and determinative method used for analysis of this sample.
The method used must be reported. If multiple methods are used for preparation and/or analysis, a separate report form must be used for each preparation and analysis method.
Report on a wet weight basis.
