EPA 600/R-01/080
September 2001
siteLAB® Analytical Test Kit UVF-3100A (UVF-3100A) developed by siteLAB®
Corporation
(siteLAB®) was demonstrated under the U.S. Environmental Protection
Agency Superfund
Innovative Technology Evaluation Program in June 2000 at the Navy Base
Ventura County site in
Port Hueneme, California. The purpose of the demonstration was to collect
reliable performance
and cost data for the UVF-3100A and six other field measurement devices
for total petroleum
hydrocarbons (TPH) in soil. In addition to assessing ease of device operation,
the key objectives of
the demonstration included determining the (1) method detection limit,
(2) accuracy and precision,
(3) effects of interferents and soil moisture content on TPH measurement,
(4) sample throughput, and
(5) TPH measurement costs for each device. The demonstration involved
analysis of both
performance evaluation samples and environmental samples collected in
five areas contaminated with
gasoline, diesel, lubricating oil, or other petroleum products. The performance
and cost results for
a given field measurement device were compared to those for an off-site
laboratory reference method,
Test Methods for Evaluating Solid Waste (SW-846) Method 8015B
(modified). During the
demonstration, siteLAB® required 37 hours, 20 minutes, for TPH measurement
of 199 samples and
13 extract duplicates. The TPH measurement costs were estimated to be
$7,090 for siteLAB®s
UVF-3100A rental option; $7,720 for the UVF-3100A on-site testing support
service option; and
$17,670 for the UVF-3100A purchase option compared to $42,500 for the
reference method. The
method detection limits were determined to be 3.4 and 6.32 milligrams
per kilogram for the
UVF-3100A and reference method, respectively. During the demonstration,
the UVF-3100A
exhibited good accuracy and precision, ease of use, and lack of sensitivity
to interferents that are not
petroleum hydrocarbons (neat materials, including tetrachloroethene; turpentine;
and
1,2,4-trichlorobenzene and soil spiked with humic acid). However, the
device showed less than
5 percent response to neat materials (methyl-tert-butyl ether and Stoddard
solvent) that are petroleum
hydrocarbons. In addition, it exhibited minor sensitivity to soil moisture
content during TPH
measurement of weathered gasoline soil samples. Despite some of the limitations
observed during
the demonstration, the demonstration findings collectively indicated that
the UVF-3100A is a
reliable field measurement device for TPH in soil.
