What part of TPH is a VOC?

What part of TPH is a VOC?

(OP)
Hello All,

I have soil contamination criteria for both toxicity and vapor emissions. My question is what information can I draw about VOC content from the results of a TPH test? If I get a hit in the gasoline range of EPA 8015B, is it possible that the results from EPA 8260 (assuming same soil sample etc) would come back clean?

Thanks!

RE: What part of TPH is a VOC?

No, propane, benzene, and other components of gasoline are all volatile organic compounds and will show up in the EPA 8260B test.

RE: What part of TPH is a VOC?

418.1 is really more of a screening test. It's quantifible and reproducable, but there are non voc chemicals/constituants that can give false positive values - Natural organic matter in the soil being one of those constituants.

So, yes, you can have a clean 8015 and a dirty 418.1.

f-d
