What is OilScreenSoil (Sudan IV)® used for?
The OilScreenSoil (Sudan IV)® field screening test kit is an inexpensive,
simple, and virtually instant qualitative test for identifying the presence of
Oils (LNAPLS and DNAPLS) in soil. The only restriction is that the contaminants
be sufficiently light in color to ensure the dye can be seen. This product is
also suitable for screening TCE, TCA and PCE materials. The soil test kit was
designed to overcome the historic difficulties with field screening tests and
was therefore developed according to a very specific set of criteria:
- The OilScreenSoil (Sudan IV)® kit is a "go"/"no-go" soil test kit for the
presence of oil (LNAPLs and DNAPLs)
- The OilScreenSoil (Sudan IV)® test kit will detect virtually all oils down
to approx 500ppm of TPH
- OilScreenSoil (Sudan IV)® results are immediately available and require no
specialized measurement equipment
- OilScreenSoil (Sudan IV)® tests have simple, easy to read instructions and
can be used by utility or industrial contractors after a couple of minutes
training.
How Does The OilScreenSoil (Sudan IV)® Test Kit Work?
Suspected petroleum or DNAPL contaminated soil is added to the sample bottle,
to which potable water is also added and the contents shaken vigorously. A
rapidly dissolving cube is attached to the cap. The cube has a Sudan IV based
red oil soluble dye and a fluorescing yellow/green water soluble dye disbursed
thoughout its surface.
The red dye stains petroleum products (including DNAPLs) red; while the green
dye colors the water to provide a visual contrast between the two colours. When
free petroleum floats to the surface it attaches to an EPS bead that is supplied
with the kit and/or attaches to the walls of the container. From concentrations
below about 2,500 ppm to the limit of detection (which is about 500 ppm) the EPS
bead will turn pink. At very low concentrations we suggest using an used kit as
a comparison for the colour depth of the EPS bead as the color change may be
slight.
The range of detection is approximate because a soil's affinity for oil will
vary. Since DNAPL is heavier than water it is typically seen towards the bottom
of the jar. The DNAPL can also be seen as red "beading" on the sides of the
container.
OilScreenSoil (Sudan IV)® Does Not Replace Quantitative Field Screening
Test, However:
During the excavation of contaminated soil, the Oilscreen Soil (Sudan IV)®
soil test kit will permit rapid assessment of the depth and direction of
contaminants, thus reducing the time and costs typically associated with field
screening methodology.
NOTE: Esters (detergents) are the only known substance to interfere with the dye s ability to
stain petroleum hydrocarbon products. This may be applicable when screening for Ester based
(i.e. synthetic) motor oils.
Industries That Would Benefit From Using The OilScreenSoil (Sudan IV)® Kits
Include:
Forestry, environmental, aerospace, shipping/marine, railways, manufacturing,
petrochemical, utilities and construction.
The OilScreenSoil (Sudan IV)® kits are currently used for a wide variety of
purposes including:
- Checking for leaks from above ground storage tanks into soil
- Checking for leaks from equipment into soil
- Checking for leaks from utility transformers into soil
- Detecting perimeters, depths and directions of oil spills in soil
- Detecting oil leaks in sumps near tanks
- Detecting chemicals at Dry Cleaner Remediation sites
