This sample consists of 10g of soil containing base/neutrals and acids in soil.

Four samples have been provided for your convenience (multiple methods, multiple analysts, etc.)

The soil has been chemically stabilized with 1mL of acetone to minimize degradation of the sample.

The evaluation of the results will be based on study statistics as required be NELAC.

The standard may not contain all of the compounds listed on the Report Form in accordance with NELAC standards.

For analytes not detected, report a zero “0” or a “<” and your detection limit.

Extract the complete contents of a single vial.  Transfer entire contents of one vial to extraction vessel.  Rinse vial and cap with extraction solvent.

Note: Sample extracts and calibration solutions should be in the same solvent.

Analyze the Extract using the appropriate Semi-Volatile Organics method for which you are seeking accreditation.

Determine the concentration of the analytes listed, and report your results on the organic analysis data sheet provided.

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 all results on a wet weight basis, do not correct for moisture.

Assume a 10g sample size for all calculations.
