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 per cubic yard. Nutrients were added according
to recommendations and aeration provided.

Remediation cost estimated at:
$5400.00
Suggested Dosages:
1-3 gallons of mixed supernat 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 product per cubic
meter to get the most even distribution in the soil, depending on aeration
technology. Second application may be necessary
* These are estimates only. The
cost of Nutrient activator is included in the 10 and 25 cubic yard estimate.
For larger projects, the addition of Nutrient activators and Slow Release
Oxygen will be estimated based on soil attributes.
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 )
