Save time and money in phase II environmental site assessments & excavations, soil remediation, dry-cleaner remediation projects, government agency compliance testing and training programs & monitoring remediation activities with our detect-oil-in-soil kits
Using Detect-Oil-in-soil test is efficient and user friendly. The test jar should be filled to the indicator arrow (approximately halfway or 1 oz) with soil, with clean water being added to the second indicator arrow on the jar. The lid should be tightened, and the jar should be shaken until the cube stuck to the inside of the lid is completely dissolved (depending on which test kit you are using – crimson, sudan IV or cobalt)
The more contaminants that are present in the soil, the more dye is produced, both in terms of quantity and intensity. The amount of dye (color presence and intensity) you observe corresponds to the petroleum concentration. Almost everyone with normal color vision is able to discern the color of the EPS bead at ~500 ppm tph. Veiw Gallery of test kits with contamination at ~500 ppm tph ~2500 ppm tph ~5000 ppm tph.
**Detect-Oil-In-Soil tests should be used exclusively to detect the presence or absence of contamination. Since every test is unique, these suggestions are simply intended as general guidelines.
Some examples of where Detect-Oil-In-Soil tests are used are as follows:
Oils and petroleum-based hydrocarbons are the ONLY substances that the Detect-Oil-In-Soil test can detect. Some of the new synthetic oils cannot be screened since they are typically ester-based rather than petroleum-based. It will only provide a “presence indicator” between ~400 and ~500 ppm TPH or above.
For the detection of gases (compounds with 4 carbons or less) or for usage with heavy bituminous materials like asphalt, Detect-Oil-In-Soil kits are NOT appropriate.
