Service Station Ground Water
Bioremediation Treatment
Project # 10081

Project Situation

• Ground Water contamination of gasoline containing MTBE - Methyl Tert-Butyl Ether and TBA - Tert-Butyl Alcohol.
• Pump and treat method was chosen as the best available technology for this project.

Products/Technology Used

• Product # 75XXX – BioWorld Bioremediation Enhancer
• Product # 32XXX – BioWorld Hydrocarbon Digester Microbes

Results

Sample chain of custody was completely handled by the service station property owner – a major oil company.  Results taken at third week of BioWorld treatment - retention time of 8 hours on a constant flow system.  

Influent

MTBE@140 PPB       

TBA@430 PPB       

Outflow sample after Bioremediation in aerated tank:

MTBE@3.9 PPB     

TBA@110 PPB

Outflow sample after addtional treatment unit:

MTBE                              Non-Detected

TBA                                 Non-Detected

NOTE: Prior to BioWorld Products being applied, an enzyme product was evaluated with a 30% reduction in MTBE and TBA.  The enzyme product was 3 to 4 times the cost of BioWorld Treatments.  The enzyme product required flow to pass through 3 stages of filters that would clog and release the MTBE and TBA.
