CASE HISTORY 82790
*This customer has requested anonymous
disclosure discretion, please contact Bio Rem for additional project
information.
|
SITE: |
A truck and auto-fueling plaza. |
|
BIODEGRADED MATERIAL: |
Gasoline and diesel fuel. |
|
SITE SURVEY: |
A tank area that had contained both diesel and gasoline
tanks was discovered to have actionable contamination from several leaks
in the unleaded gasoline tank. The leaking tanks were removed from the
tank pit area. Definition and characterization revealed that not only the
tank area was contaminated, but also the contaminant plume had migrated
under an area where a new building was being constructed. Initial
laboratory analysis revealed TPH (Total Petroleum Hydrocarbon) levels of
23,000-ppm using U.S. EPA Method 8015, modified. These levels made the
site actionable. |
|
METHOD: |
Due to the extent of the contaminant plume and that a
portion of the contamination was located beneath a new building under
construction, bioremediation was selected as the most economical method
for this site. Bio Rem’s Augmented Insitu Subsurface Bioremediation
Process™ was selected. Bio Rem’s H-10 product was cultured and
propagated on site. The batch solution was then placed into the
contaminate plume. V.O.C. readings were taken and recorded.
Bioremediation began on Sept. 19, 1990 and
V.O.C.
readings below actionable levels were observed on Dec. 10, 1990. Final
samples were obtained and forwarded to an independent laboratory for
verification of results. U.S. EPA Method 5030/8020 revealed non-detect
results. |
|
COMMENTS: |
By utilizing Bio Rem’s bioremediation process and
products, the property has no tie to a disposal site. The owners avoided
considerable expense in eliminating contamination from beneath a new
building. In addition, the owners have no PRP (Potentially Responsible
Party) liabilities as the gasoline and diesel contamination was
eliminated. |
