EOSPRO
DESCRIPTION
EOS PRO is a nutrient-enriched, DoD-validated, emulsified vegetable oil (EVO). EOS PRO is engineered to quickly stimulate microbial activity while providing long-term nourishment to enhance anaerobic bioremediation of chlorinated solvents, nitrates, perchlorate, energetics, acid mine drainage, and other recalcitrant chemicals in contaminated groundwater. EOS PRO can also be used to reduce redox sensitive metals and radionuclides. The negative surface charges on the droplets combined with small droplet size promote effective transport in the subsurface. EOS PRO benefits include:
• Biostimulating vitamins and nutrients
• Rapidly-biodegradable substrates to “jump start” bacterial growth
• Slow release biodegradable substrates to promote long-term biological activity
• Engineered for effective transport in the subsurface
• Small oil droplet size
• Negative surface charge
• Neutral pH
• Extensive third-party validation
EOS PRO incorporates the patented EOS® technologies that clients have trusted for more than a decade. Domestic supply made in the USA with US farmed soybeans.

HANDLING & STORAGE
EOS PRO is shipped as a ready-to-use concentrated emulsion that can be diluted with water in the field to prepare a high quality suspension for easy injection. EOS PRO has a low viscosity and can be distributed with commonly available pumps or by continuous metering with a diluter (e.g., Dosatron™). Dilution ratios for EOS PRO typically range from 4:1 to 20:1 (water: EOS PRO) depending on site conditions. EOS PRO injections should be followed with additional chase water to maximize distribution of EOS PRO into the formation.
For best performance, use EOS PRO within 60 days of delivery and store at a temperature between 40°F (4°C) to 100°F (38°C).
