The figures below represent data from recent lab tests in which our process was applied to soil contaminated with crude oil. A 94% reduction in TPH was observed following the 21-day bio-treatment period . The rate of biodegradation was greatest during the first seven days of the test. Note: this study was conducted in the laboratory under ideal conditions in order to demonstrate the effectiveness of our process. Results in the field will vary.

Fig.1 TPH levels in soil at each of four time points during treatment with microbial consortia and nutrients shows majority of observed degradation took place within first seven days of test. Degradation continued through day 21, although at slower rates.

Fig.2 One phase exponential decay model of TPH degradation over time. Average rate of degradation was calculated at ±2049 mg/kg*day-1
