Technology Description:

The OIL-IN-SOIL™ field screening test kit is an inexpensive, simple and rapid qualitative sampling test for identifying the presence of hydrocarbons including LNAPLs and DNAPLs in soil. The OIL-IN-SOIL™ test kit is a visually enhanced version of the old Soil-Water Shake Test for the presence of oils and petroleum products. Users add soil to a line on the label, add water to another line on the label and shake the jar to release the dyes. The Kit comes in 3 colors: One kit uses the original SUDAN IV which colors the hydrocarbon red. The OIL-IN-SOIL™ Kits also comes in a Royal Blue color called OIL-IN-SOIL™RB . A colored ring or spots indicates the presence of oil or petroleum at above 2,500 ppm.TPH). A Styrofoam ball turning pink or light blue, depending on the dye used will indicate hydrocarbon down to 500 ppm. Many DNAPLs will give indications below 10 ppm because of their ability to penetrate the styrene use din the jar.

Application:

The OIL-IN-SOIL™ field screening test kits are useful tools for reducing the cost of Phase I and Phase II site assessments, by reducing the time and costs associated with delineating the perimeter, depth and direction of spills in soil. They are also often used with core samples to identify organic substances.


Environmental Benefits:

Rapid delineation of hydrocarbons and DNAPL spill boundaries in soil, results in more rapid removal of contaminants from the environment. The OIL-IN-SOIL™ kit uses a deminimus quantity of Sudan IV which is encapsulated in a soluble cube – thus decreasing the hazards to the test user from airborne particulate Sudan IV and overcoming the problems associated with disposal of larger quantities of a mutagenic dye. We have recently switched to a new manufacturer whose dye is non mutagenic.

Performance:

The OIL-IN-SOIL™ kits provide an inexpensive, consistent tool for the detection of hydrocarbons (+- 500 ppm TPH) in soil. They are easy to use and require minimal training – thus reducing the need for ongoing expensive technical support on site. The OIL-IN-SOIL™ kits have been sold commercially for several years and are used for Phase I and Phase II site assessments by most major environmental companies and several utility companies throughout the USA .

Limitations:

The only known restriction is that the petroleum or DNAPL be sufficiently light in color that the red dye can be seen and that the water added to the kit be clear enough to see the dye and warm enough to dissolve the soluble cube in the kit. The kits are NOT INTENDED as analytical tools – they were designed as presence/absence indicators to 500ppmTPH.
