Petro-Clear
- Case study
Hydrocarbon Contaminated Soil Problems
in situ - Underground Storage Tank remediation
An underground leaking motor oil
storage tank went unnoticed and unemptied for 15 years. Contamination Area: Two
batches of soil were contaminated with motor oil.
In situ treatment: Soil was treated
with 2 gallons of Petro-Clear IC per cubic yard. Nutrients were added according
to recommendations and aeration provided.

Suggested Dosages:
Hydrate 2 lbs of Petro-Clear in 5 gallons of unchlorinated water
Dispense hyrated product approx. 1-3 Gallons per cubic
meter of soil, use the higher dose for high levels of contamination to reduce
the completion time. Apply initial strength of 1 gallon of supernat per cubic
meter to get the most even distribution in the soil, depending on aeration
technology. Second application may be necessary.
Product should be
applied as soon as possible after the oil spill or leak has occurred. Most
effective when soil temperatures range from 5 to 45º C. Bioremediation in
soil will work so long as the ground is not frozen although the process greatly
accelerates once the soil has reached a temperature above 50°F. For optimum
performance, these temperature considerations must be addressed and nutrient
and oxygen levels must be maintained at proper levels. Effective over a wide pH
range (6.0 to 8.5; optimum 7.5 )
