Petrochemical & Spill Characterization
Quantifying petroleum impacts using Canada-Wide Standard carbon ranges.

CWS carbon fractions
F1 (C6–C10), F2 (C10–C16), F3 (C16–C34), F4 (C34–C50). Combined with BTEX and PAHs, this is the standard package for vapour-intrusion assessments and Phase II Environmental Site Assessments.
