The TPH in Soil Certified Reference Material (CRM) sample consists of a single amber glass sample jar, sealed with a Teflon liner, containing approximately 100 grams of material. This soil is typical of that found in the backfill surrounding a leaking underground diesel storage tank (LUST). Being an actual waste sample the analyst is challenged by the same preparation problems, analytical interferences, etc. as is typical for similar matrices received by the laboratory for analysis. Rigorous analyses identified, quantified, and certified the Total Petroleum Hydrocarbons (TPH) listed on the enclosed Certificate of Analysis. The sample has been analyzed by 20 laboratories in a round-robin to meet the requirements specified by the EPA/AALA RM-03, and ISO Guides 34 and 35. The sample was certified by USEPA Method 8015B, and is suitable for use by this and other similar methods.
