We are experts pioneering the next innovation in remediation, bringing sustainable solutions and cost effective results to our clients world-wide.
EOS Remediation, founded in 2002, is based in Raleigh, North Carolina. Since its incorporation, EOS Remediation has earned and maintained industry-leading status in the area of enhanced in situ remediation of chlorinated and recalcitrant compounds since being featured in the 2006 protocol published by SERDP/ESTCP .
U.S. Patents #RE40448, #RE40734, Australian Patent #782548, and Canadian Patent #2,394,068 are our original patents covering the use of emulsified oils for the bioremediation of groundwater contamination. Our emulsified oil substrate (EOS®) resulted from more than 11 years of research and testing from accomplished remediation scientists and engineers. The on-site success of enhanced in situ remediation using our engineered formulation has been documented in countless papers and published in numerous scientific journals, making our emulsified vegetable oil products the most-tested and accredited option available.
Our products are specifically engineered and designed for a cost-effective, in situ treatment of soil and groundwater.
EOS PRO, our flagship product, is an emulsified vegetable oil substrate blended with nutrients and vitamins used to remediate contaminated groundwater by dynamically stimulating anaerobic biodegradation and biotransformation
EOS PRO is:
- A water-miscible emulsified vegetable oil concentrate
- Safe and easy to handle in the field
- Promotes enhanced reductive dechlorination for three years or longer at most sites
- A Green Technology and is non-toxic to the environment
- Engineered for maximum distribution in the aquifer
- Effective in reducing chlorinated solvents, perchlorate, explosives (such as RDX, HMX and TNT), acid rock drainage, metals immobilization and other recalcitrant chemicals
EOS Remediation’s technical support provides the critical bridge between our research, products and field implementation. Our engineers and scientists are helpful and responsive, often assisting in designing client projects or participating in on-site consultations. The quality of our client support and our commitment to a quick response is unmatched.

What is Bioremediation?
Bioremediation is a cost-effective, sustainable, natural approach to cleaning up contaminated soil and groundwater through the use of biological agents such as bacteria, microbes, fungi, and other organisms of their enzymes.
The process of bioremediation requires two key components:
- Electron Donor: typically hydrogen which can be derived from a carbon source such as vegetable oil, lactate, or petroleum-based contaminants
- Electron Acceptor: a respiring agent like oxygen, although many microorganisms are capable of using other agents such as nitrate, sulfate or even a chlorinated solvent (PCE or TCE)
Contaminants can fill either role of electron donor or electron acceptor. For example a petroleum based hydrocarbon could be a usable carbon source for certain bacteria, similarly a chloringated solvent such as tetrachloroethene (PCE) could be utilized by a different strain of bacteria as an electron acceptor.
A critical understanding in the success of a bioremediation project is determining the role of the contaminant at the site and what key component is required to foster bioactivity. Below are two tables illustrating some common examples of electron donors and acceptors.
If the correct components are available at a conta...
If the correct components are available at a contaminated site, the process of bioremediation can occur naturally with no human intervention. This is known in the industry as monitored natural attenuation (MNA) because all the components needed for cell growth and reproduction are present and bioremediation occurs without outside stimulus.
When an electron donor or acceptor are lacking, often biostimulation is an option to provide the missing component. And when the microorganisms themselves that perform these reactions are not present, bioaugmentation can allow the reaction to continue and facilitate bioremediation.
Biostimulation: The addition of nutritional amendments to increase microbial metabolism and to encourage biodegradation (often organic compounds, e.g. EOS indigenous microbes present, but substrates and/or nutrients are limited and must be added to foster bioactivity).
Bioaugmentation: the addition of beneficial microorganisms to improve the rate or extent of biodegradation (e.g. Indigenous microbes not present or in low quantity so organisms are added).
