Microbial nutrients are injected into soil and groundwater to promote dechlorination reactions with VOCs in the ground/groundwater.
This product provides a low-cost method of purifying deep underground soil and groundwater without the need to excavate and dispose of contaminated soil.
Dechlorination and decomposition of pollutants using safe and inexpensive bio-nutrients

Comparison Testing of cis-1,2-dichloroethylene Decomposition

MED Bio-nutrient"
Characteristics of MED Bio-nutrient
- Less expensive than polylactic acid, higher fatty acids, and amino acids traditionally used as nutrition sources.
- Safe, plant-derived material is harmless to humans, animals, and plants.
- Contains organic acids and amino acids to provide nutrients needed by anaerobic microorganisms.
Example VOC decomposition sequence

* PCE: Tetrachloroethylene; TCE: Trichloroethylene; DCE: Dichloroethylene; CE: chloroethylene
- Determine the number of injections and amount per injection based on detailed soil/groundwater contamination surveys.
- Determine the injection depth and specific location by analysis of geologic structure and concentration distribution data.
- Drill MED injection holes into the ground and inject using a pump.
