Major Ground Oil Spill - Manufacturing Company

Biological Treatment Summary

The Situation

A manufacturing company experienced a major ground oil spill, which involved 49,000 cubic ft. of contaminated soil. Testing revealed an average Total Petroleum Hydrocarbon (TPH) contamination level of 2,210 mg/L.

The Solution

United-Tech, Inc. implemented a biological treatment program utilizing OBT® Oil Degradation Treatment. The program consisted of the normal treatment protocol of United-Tech, Inc., which includes:

1. Excavating the soil and placing it in a containment windrow.
2. Watering down the soil to achieve optimum moisture content.
3. Spraying the contaminated area with OBT®
4. Covering the windrow with heavy mil plastic.
5. Maintaining soil moisture and turning the windrow every week.

The Results

Four weeks later, composite sample test results revealed non-detectable limits* of TPH. Total clean-up of this project was achieved with OBT® Oil Degradation Treatment.

* = (Limits below 100 ppm are acceptable EPA requirements for clean-up)
