"The UVF-3100A exhibited the following
desirable characteristics of a field TPH measurement device; (1)
good accuracy, (2) good precision, (3) high sample throughput, (4)
low measurement costs and (5) ease of use."
Page 100, EPA Pub No. 600/R-01/080
The U.S. Environmental Protection Agency
conducted a performance study called "Field Measurement Technologies
for Total Petroleum Hydrocarbons in Soil" by evaluating Sitelab and
six other manufacturers through the Superfund Innovative Technology
Evaluation (SITE) program. The project was directed by the
Office of Research and Development's National Exposure Research
Laboratory in Las Vegas, Nevada. Tetra Tech, Inc. was contracted to manage this
$800,000
project. See
»Engineering
Award for details.
During the final field demonstration, Sitelab tested over 200
samples using our UVF-3100A analyzer for both Gasoline Range
Organics, Extended Diesel Range Organics and Total Petroleum
Hydrocarbons (TPH as combined GRO and EDRO). Sitelab was the
only developer who performed and reported TPH as well as GRO and
EDRO separately, just like the reference laboratory.
Samples consisted of Performance Evaluation spiked soils, liquid
interference samples and a variety of environmental samples from
five different contaminated sites located throughout the United
States. All samples were split and sent to a certified
laboratory for confirmatory analysis using EPA Method 8015M.
