CoBupHMG
DESCRIPTION
CoBupHMg™ is a premium colloidal suspension of alkaline solids providing long-term, slow release adjustment of pH in acidic aquifers to optimize levels for biodegradation and immobilization of some some dissolved metals. CoBupHMg’s patented formulation provides:
• Equilibrium pH of ~10 in a 10:1 dilution (DI water:CoBupHMg), minimizing the risk of overshooting the pH by buffer addition
• Micron scale, negatively charged particles promote distribution from the injection point
• Can be used in combination with our emulsified oil products.

HANDLING & STORAGE
CoBupHMg is shipped as a ready-to-use concentrated suspension of alkaline solids that can be easily diluted with water in the field. CoBupHMg has a low viscosity and is amenable to pumping with commonly available pumps. Before dilution, agitate to ensure product is adequately mixed. Dilution ratios typically range from 1:1 to 4:1 (water: CoBupHMg) depending on site conditions; CoBupHMg injections should be followed with additional chase water to maximize distribution.
For best performance, use CoBupHMg within 60 days of delivery and store at a temperature of 40°F (4°C) to 100°F (38°C).
