Groundwater Treatment of BTEX
Project: Treated 12,000 cubic yards of petroleum contaminated sandy-silty soil and groundwater
Client: Gate Petroleum
Location: South Central Florida
Scope of work: In-Situ Bioremediation
Project cost: $78,000 (Included only microbial products)
Source of contamination: Leaking UST
Project duration: 9 months
Description: A Geo-Probe was used to inject the microbial products into 100 borings. Two treatments have been performed since the underground storage tanks were upgraded.
In Situ Groundwater Treatment of Gasoline
Project: Treated 300 cubic yards of gasoline contaminated silty sands and groundwater
Client: Private Service Station Owner (Former Exxon station)
Location: Near Dayton, Ohio
Scope of work: In-Situ Bioremediation
Project cost: $7,575 (Included earthmoving, labor, and all bioremediation materials)
Source of contamination: Leaking UST
Project duration: 3 weeks
Status: Completed
Description: An open pit was excavated as a means to inoculate the contaminated groundwater. A liquid mixture of our microbes and nutrients was pumped into the pit and then agitated by the backhoe. Two treatments were performed during a two-week time period. Three weeks after the initial treatment, contamination levels dropped below action levels and the project was closed.
Free Product (Diesel) in Groundwater
Project: Treated 2,500 cubic yards of diesel in groundwater
Client: Mission Bay Resort Hotel
Location: San Diego, California
Scope of work: In-Situ Bioremediation
Project cost: $175,000 (Included labor and materials for treating groundwater 4 times)
Source of contamination: Leaking UST
Project duration: 12 months
Status: Completed
Description: The plume for this site was located below the parking garage for a resort hotel in southern California. Injection wells were installed and used as a means for application of the microbes into the soil. In addition to using our own consortium of microbes and nutrients, we added a bio-catalyst on this project to provide additional oxygen for the microbes. Twelve months after the initial treatment, the TPH dropped from 130,000 ppm to less than 1 ppm.
In Situ / Ex Situ Soil Treatment of Diesel
Project: Treated 100 cubic yards of diesel contaminated sand and silts
Client: Private Service Station Owner (Gambler Service Station)
Location: Near Gary, Indiana
Scope of work: In-Situ Bioremediation
Project cost: $1,400 (Included labor and materials for treating soil once)
Source of contamination: Leaking UST
Project duration: 4 months
Status: Completed
Description: An area of 25' x 25' x 5' was excavated, treated with microbes and nutrients, and then placed back into the pit. A small, rubber tire back-hoe was used for the earthmoving during this project.
Ex Situ Soil Treatment of Waste Oils and Diesel Fuel
Project: Treated 450 cubic yards of waste oils and diesel fuel in soil and rock
Client: Southern Arizona Mining Site
Location: Near Tucson, Arizona
Scope of work: Ex-Situ Bioremediation
Project cost: $21,600 (Included earthmoving equipment, treatment, bioremediation supplies and all analytical sampling)
Source of contamination: Leaking USTs and mining equipment
Project duration: 6 weeks
Status: Completed (Catalina BioSolutions treats a new cell of 200-400 cubic yards of soil every 4-8 weeks)
Description: A treatment cell has been constructed to hold 250-500 cubic yards of soil. Approximately once a month, Catalina BioSolutions turns the 18-22" high soil in the Bio-Cell and sprays the soil down with the liquid microbial product.
Soil and Groundwater Treatment of PCE
Project: Treated 100 Cubic Yards of PCE Contaminated Clay Soil and Groundwater
Client: Former Dry Cleaners
Location: Warren, Michigan
Scope of work: In-Situ Bioremediation
Source of contamination: Leaking UST
Project duration: 2 months
Status: Treatment Completed
Description: A series of 2 inch wide injection wells were drilled to a depth of approximately 10 feet. Our bioremediation products were injected in liquid form into each well. One performance well was left untreated in the center of the source area. The analytical results above are from that performance well.
Soil Treatment of Chlordane
Project: Ex-Situ Pilot Test; Silt and Clay Soils
Client: Former Pesticide Manufacturing Plant
Location: Eastern North Carolina
Scope of work: Ex-Situ Bioremediation
Source of contamination: Several Years of Surface Spills
Project duration: 4 months
Soil & Groundwater Treatment of Tetrochloroethene (PERC)
Project: Treated 200-300 cubic yards of Tetrachloroethene contaminated soil and groundwater
Client: Dry Cleaners
Location: Lexington, Kentucky
Scope of work: In-Situ Bioremediation
Project cost: $3,500 per treatment (Included products and labor)
Source of contamination: Leaking UST
Project duration: 1 Year
Description: A microbial solution was injected into a series of 2 inch treatment wells. The cleanup target levels for this site are 5 parts per billion of Tetrachloroethene.
Soil and Groundwater Treatment of MTBE
Project: Treated 4,200 cubic yards of petroleum contaminated sandy-silty soil and water
Client: Speedy Express Service Station
Location: Walterboro, South Carolina
Scope of work: In-Situ Bioremediation
Project cost: $30,000 (Included only microbial products)
Source of contamination: Leaking UST
Project duration: 15 months
Description: A series of 2-inch diameter slotted PVC was installed to a depth of 8-10 feet. Approximately 200 gallons of our microbial and nutrient product was injected into each well: three times over a period of nine months.
