What Is OilScreenSoil (Indigo Blue)® Used For?
This product was developed in response to a request for a "non Sudan IV
based" instant" oil screening kit that will identify the presence of petroleum
products in soil, sand and gravel. In order to provide a maximum visual contrast
against dark or red soils this kit stains hydrocarbons and oils a bright royal
blue color.
The OilScreenSoil (Indigo Blue)® 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:
- OilScreenSoil (Indigo Blue)® kit is a "go"/"no-go" soil test kit for the
presence of oil (LNAPLs and DNAPLs)
- The OilScreenSoil (Indigo Blue)® test kit will detect virtually all oils
down to approx 500ppm of TPH
- OilScreenSoil (Indigo Blue)® results are immediately available and require
no specialized measurement equipment
- OilScreenSoil (Indigo Blue)® 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 (Indigo Blue)® 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 blue water
soluble dye disbursed thoughout its surface.
The blue dye highlights petroleum products or DNAPL by turning them a bright
blue. 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 a pale bluish shade. 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 blue "beading" on the sides of the
container.
OilScreenSoil (Indigo Blue)® Does Not Replace Quantitative Field Screening
Tests, However:
During the excavation of contaminated soil, the OilScreen 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 (Indigo Blue)®
Kits Include:
Forestry, environmental, aerospace, shipping/marine, railways, manufacturing,
petrochemical, utilities and construction.
The OilScreenSoil (Indigo Blue)® 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
