New Engineered Solution: PLUS
EOS Remediation has been developing products based on the latest scientific discoveries in groundwater remediation since we developed the technology of using emulsified vegetable oils (EVO) for Enhanced Reductive Dechlorination (ERD) for the research arm of the US Department of Defense over 20 years ago. Recent research has shown that adding increased fixed nitrogen and vitamin B12 accelerates ERD rates [...]
Sustainable, Biobased Technologies for Green Remediation
For over 20 years, customers have turned to EOS Remediation for natural, science-driven solutions for aquifer and soil decontamination. Now, increasingly, sustainability and green remediation are not only good for the environment, but also good for business. In 2020, the Sustainable remediation column from Remediation magazine summarized the growth in our industry stating, "the remediation industry examined the highly consumptive nature [...]
Product Spotlight: CoBupH
Tech Tip CoBupH is a safe, easy-to-use, long-lasting, colloidal buffer that can be mixed with any EOS® emulsified oil product or used alone for long-term pH control. At many sites, acidic groundwater increases metals mobility and inhibits contaminant biodegradation. CoBupH was recently used in a biobarrier with EOS Pro to treat groundwater containing RDX, HMX, and perchlorate. A [...]

Dhc Requires Nitrogen for Optimum Growth
Tech Tip Nitrogen is an essential nutrient for the growth of microorganisms, including dechlorinating bacteria. Some bacteria in nutrient-limited (oligotrophic) environments can convert atmospheric nitrogen (N2) to a form that can be used for growth [ammonium (NH4+)]. However, this process requires significant metabolic energy. More importantly, not all dechlorinating bacteria are capable of N2Â fixation (Ju [...]
Injection Suspensions
Tech Tip Liquid suspensions containing zero valent iron (EOS ZVI), pH buffers (CoBupHMG), magnetite, or other solid materials are often injected during in situ remediation projects. However, when the particles have a density greater than water (> 1 g cm3), there is a potential for settling at the bottom of injection wells and other flow stagnation [...]
