Organics by ASTM Method D2974
Used to determine the moisture content, ash content, and percent organic matter in soil.
http://www.astm.org/Standards/D2974.htm
Organics by EPA Method 8260B
Determines most volatile organic compounds with boiling points below 200 C. Collect grab samples in 40 mL glass screw cap VOA vials with Teflon-lined silicone septa. If residual chlorine is present collect the sample in a 125 mL container which has been pre-preserved with sodium thiosulfate solution, swirl gently and then transfer to a 40 mL VOA vial. Cool to 4 degrees C and adjust pH to <2 from time of collection until analysis.
