Bioremediation
of Petroleum Hydrocarbon
Project #1015
A former underground heating oil storage tank area at a California winery contained
approximately 6,000 cubic yards of contaminated soil.
Twelve treatment cells were
constructed containing 500 cubic yards per cell. Initial Total Petroleum Hydrocarbon
concentrations in the soil averaged 4,000 ppm. The targeted level for closure of each cell
is 100 ppm.
BioWorldŽ Bioremediation Technology was selected as the most efficient and
cost-effective solution for clean up. Soluble nutrients, vitamins, and minerals, in
conjunction with hydrocarbon digesting microbes, were added monthly for 3 months using a
water truck. Mechanical discing and water additions continue to provide aeration and
maintain an appropriate moisture content in the cells.
After 11 months, the project is
complete with no further clean-up action required.
