Emulsified Vegetable Oil for In Situ Bioremediation
Newman Zone®
A Balance of Fast and Slow Release Electron Donors
Newman Zone® is Proven –
Newman Zone® was the first EVO bioremediation product on the market and tens of millions of pounds have been successfully used around the world. Newman Zone® is a blend of fast and slow release electron donors proven effective in treating chlorinated solvents and other contaminants.
Newman Zone 55 and 60E Differences
| Feature | Newman Zone 55 | Newman Zone 60E |
|---|---|---|
| Fast-Release Donor | Lactate-based | Ethanol-based |
| Vegetable Oil Content | ~60% | ~65% |
| Hydrogen Release Profile | Balanced (lactate + slow-release oil) | Balanced (ethanol + slow-release oil) |
| Performance Profile | Balanced startup with sustained long-term treatment | Faster initial response with sustained long-term treatment |
| Storage Characteristics | Requires chilled storage for long shelf life | No refrigeration required; ethanol stabilizes product |
Why Newman Zone®
Newman Zone is a cost-effective electron donor trusted for its consistent performance and long-term reliability in the field. Developed for practical use under real site conditions, it provides a dependable approach to in situ treatment across a wide range of applications.
Balanced, Long-Lasting Performance
Combines rapid microbial stimulation with long-term hydrogen release to support sustained, in situ treatment over time.
Industry-Leading Droplet Size
Ultra-fine oil-in-water emulsion allows movement more effectively through tighter soils, including silts and clays, where larger emulsions struggle.
Flexible Application Methods
- Direct push injection
- Injection wells
- Recirculation systems
- Application to excavated source areas prior to backfilling
Proven Technology
Decades of Real-World Results: Since its initial production in 2002, millions of pounds have been applied at thousands of sites worldwide.
Technical Details
How It Works
- Fast-release donor (lactate): Rapidly creates anaerobic conditions and stimulates microbial growth within hours
- Slow-release donor (vegetable oil): Ferments over time to produce hydrogen and volatile fatty acids
- Result: Sustained biological activity that supports complete contaminant breakdown
Soybean oil EVO is an ideal slow release electron donor for chlorinated solvent bioremediation. EVO releases hydrogen for several years with a single injection event.
SLOW RELEASE ELECTRON DONORS
- Newman Zone Small Droplet EVO – Factory made emulsions with oil droplets under one micron for maximum mobility. EVO formulations have 55%-72% fermentable content and 46%-60% soybean oil by weight and 4-8% fast release donor (lactate or ethanol)
Application & Handling
Newman Zone 55 is designed for flexible field application:
- Diluted prior to injection (typically ≤5% oil by volume)
- Low viscosity after dilution—pumps easily like water
- Suitable for:
- Direct push injection
- Injection wells
- Recirculation systems
- Excavation/backfill applications
Common treatment approaches include source area grids and permeable reactive barriers.
Product Characteristics
- ~60% vegetable oil concentrate
- Submicron droplet size (approx. 0.15–0.60 microns)
- White, opaque liquid
- Food-grade ingredients
Packaging & Storage
Available in:
- 5-gallon pails
- 275-gallon totes
- Bulk delivery (ISO tanks or tanker trucks)
Shelf life:
- Up to 5 years in chilled storage
- 2–4 months on-site without refrigeration
USDA Certified Biobased
Newman Zone 55 is formulated with food-grade components and does not require special handling under normal use conditions.
It is also a USDA Certified Biobased Product, supporting sustainable remediation practices.
