SITE:

A petroleum jobber.

BIODEGRADED MATERIAL:

 

Gasoline.

SITE SURVEY:

 

Site and geological surveys revealed a gasoline-contaminated area down gradient from the existing fuel tanks. Precision tank testing determined that the contamination was not from the existing tanks. Borings described the contamination as resting between the 14 and 20-foot level below the parking lot. The entire property consisted of fill. A perched groundwater was encountered 12 to 14 feet from the surface.

METHOD:

 

Insitu 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. Borings were made to the 14-foot level on 10-foot centers. Through this grid pattern the H-10 bacteria and water were introduced.

 

Precise amounts of the H-10 bacteria were calculated to match the concentration levels of contamination. A program for monitoring was started just prior to the introduction of the bacteria. Regular readings were made and recorded through the use of a field photo ionization detector (PID). When PID readings were at the non-detect level, water samples were collected via U.S. EPA Methods, and sent to an independent lab for verification. Six weeks after placement of the Bio Rem H-10 bacteria, the lab confirmed non-detect levels of BTEX.

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 consideration.
