SITE:

Parcel delivery facility.

BIODEGRADED MATERIAL:

 

Diesel fuel.

SITE SURVEY:

 

Site and geological surveys had revealed a contaminated area north of the facility and west of a diesel tank pit. The cause of the contamination was a result of two underground storage tanks (USTs). One contained waste oil and the other tank contained new oil. Both tanks had been removed and a monitor well had been installed for future monitoring and bioremediation. Initial laboratory samples revealed that the levels of contamination were actionable. Results showed levels reaching 21,960-ppm total petroleum hydrocarbons (TPH) by IR.

METHOD:

 

In situ bioremediation was approved. The contamination was treated without excavation. This was possible because Bio Rem’s proprietary H-10 bacteria works in low-level oxygen conditions. The bioremediation was conducted by placing bacteria, nutrients and water into the monitor well. Weekly monitoring of the vapor from the well indicated the progression of the treatment.

 

The treatment with Bio Rem H-10 bacteria began on Jan. 23, 1991 and the lab confirmed non-detect levels of BTEX in its report dated April 12, 1991. The results were obtained using U.S. EPA Method 8020.

COMMENTS:

 

This site has received a "no further action" status by the state authority. The property has no tie to a disposal site, with its future liabilities being eliminated from this contamination.
