Bioremediation Amendments
Electron donors and biological amendments that stimulate natural microbial degradation of chlorinated solvents and petroleum hydrocarbons.

Amendments for enhanced bioremediation
Hepure supplies a range of bioremediation amendments used to stimulate and sustain the microbial processes that degrade contaminants in soil and groundwater. These products serve as electron donors, oxygen-release compounds, and supporting amendments for both anaerobic and aerobic biological treatment.
The right amendment depends on the contaminant, the target degradation pathway (reductive or oxidative), site geochemistry, and how long the amendment needs to remain active in the subsurface.

Emulsified Vegetable Oil (EVO)
Long-lasting anaerobic electron donor that supports reductive dechlorination of chlorinated solvents.

Sodium Lactate
Soluble, fast-acting electron donor for rapid onset of anaerobic biological activity.

Beyond the primary electron donors, Hepure supplies supporting amendments for biological treatment and pH adjustment:
- Emulsified Vegetable Oil (EVO) — long-duration anaerobic electron donor for reductive dechlorination
- Sodium Lactate — soluble, fast-acting electron donor for quick biological response
- Ferrous Sulfate — supports reducing conditions and complements abiotic/biotic treatment
- Sodium Hydroxide — pH adjustment to maintain conditions favorable for microbial activity
- ECH — a bacterial supplement (bioaugmentation culture) for enhanced bioremediation where native populations are insufficient
Where bioremediation amendments fit
- Anaerobic reductive dechlorination of chlorinated solvents (TCE, PCE, DCE, vinyl chloride)
- Aerobic degradation of petroleum hydrocarbons
- Long-term plume management and polishing after primary treatment
- Sites requiring cost-effective, sustainable, low-energy remediation
- pH adjustment and creation of favorable subsurface geochemistry
