Oil in Soil Screening Kit

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 is available in two colors. One kit uses an exact replacement for Sudan IV that contains virtually no o-toluidine, which is a mutagen. This dye colors the hydrocarbon red and has a water-soluble green fluorescein for contrast. The OIL-IN-SOIL kit also comes in a royal blue color called OIL-IN-SOIL RB. The blue dye is primarily for customers with red-green colorblindness. The styrofoam ball turning pink or light blue (depending on the dye used) indicates hydrocarbon presence down to 500ppm. Many DNAPLs will give indications below 10ppm bec
