Sitelab Submits UVF Draft
Methods to U.S. EPA
Last
updated
Dec 3, 2024: Five new methods for measuring hydrocarbons using fluorescence-based
instrumentation were recently submitted for approval in U.S.
EPA's SW-846 Compendium. The methods provide quick, low cost,
quantitative results and detect a wide range of petroleum
contaminants in soil and water using solvent extraction.
Proposed method numbers and names given are below.
8000 Series: Organic Determinative
Methods
86xx UVF Determinative - New!
8630 Gasoline Range
Organics (GRO)
8640 Diesel Range Organics
(DRO)
8650 Total Petroleum Hydrocarbons
(TPH GRO+DRO)
8660 Total Petroleum
Hydrocarbons (TPH)
8670 Polycyclic
Aromatic Hydrocarbons (PAHs)
Note: 8650 uses the GRO and
DRO methods to report TPH as the sum of the two fractions. 8660
differs from 8650, it's site-specific and uses the source oil
for calibration and analysis.

Background:
These methods were peer reviewed and edited by two industry experts
and were created using U.S. EPA's SW-846 Style Guide. The format
and boilerplate descriptions used and repeated in many of the
sections were taken from these guidelines for consistency with other
methods.
Method performance tables listed in each method were
developed to meet EPA's Validation and Peer Review of U.S.
Environmental Protection Agency Chemical Methods of Analysis.
This includes general fluorescence of hydrocarbons within each
method, proficiency sample analysis and correlation to other
determinative methods. Sitelab has a large supporting data
package available complete with all the findings referenced in each
method.
Since 1998, Sitelab Corporation has been an industry
leader in providing portable UVF analyzers to
the oil and gas, environmental and remediation markets. These
methods were written to not show favortism.
Other UVF instruments made by other manufacturers
exist and can be used.
