What's in
your TPH?
Sitelab can identify if your site has gasoline, jet fuel, diesel fuel,
heating oil, coal tar or crude oils, plus fresh vs. old and
weathered petroluem contaminants! |

|
|
Sitelab's
fingerprinting procedure helps you identify the age or type of
contamination on your site at a fraction of the cost compared to
conventional laboratory forensic testing.
The proportions of a
sample’s GRO and PAH concentrations will vary depending on
how old and what type of petroleum contamination is present.
These signatures
are then compared to Sitelab's unique database
containing the signatures of hundreds of archived reference
standards, oils and samples having known petroleum sources.

Here's How
it Works... |
 |
1. Extract and prepare samples in solvent
using Sitelab test kits. Soil, sediment, water or oil (NAPL)
samples can be analyzed. See our
Test Procedures
for details. Samples only have to be extracted once. |
 |
2. Test for GRO
(BTEX): Calibrate the UVF-3100D analyzer using Sitelab's GRO
Calibration Kit on the Slot B optical filters. Test sample and
record concentration. The sample extract can be re-tested for
EPH and PAHs. |
 |
3. Test for Total PAHs
(EPH): Rotate the optical
filters to Slot A and recalibrate using Sitelab's PAH Calibration
Kit. Test sample and record concentration. |
 |
4. Test for
Target PAHs: Rotate the optical filters to Slot D and re-test
sample. Recalibrating is not necessary. The PAH
calibration kit fluoresces the same on Slot D as on Slot A, but sample
results will be lower. |
 |
5. Optional: Test
the sample for Heavy PAHs using Sitelab's TD-500D analyzer for
additional forensic analysis. It uses a similar PAH kit as the
UVF-3100, but it's sensitivity is different. It can also
detect natural organic interferences. |

What's the
Advantage? Sitelab's
field screening method provides fast and reliable forensic data
without the high cost and delayed turnaround time typically
associated with conventional laboratory techniques using GC
instrumentation. In addition, the GRO, EPH and PAH results
reported using the UVF-3100D analyzer are very accurate and will
directly correlate to the certified laboratory methods, should
confirmatory analysis be performed.
"This project is the first one I have done that had two
distinctly different sources. Kind of interesting how the
ratios show it and then the client confirmed it. Nice when
science works!" Kelly Bergdoll,

Latest Press
Release:
Battelle Memorial Institute uses
Sitelab on a large sediment site near Lake Michigan.
Sitelab's PAH fingerprinting data and GPS coordinates for 100
sample locations were used to map the sediment contamination.
Test results revealed several "hot spots" and where fresher
versus older crude oil exists in the river. Click image
