Milk to be used to remove chlorinated solvents trichloroethylene (TCE) and tetrachloroethene (PCE) from soil

Milk is touted as a good source of calcium and vitamin D, but it could also be the remedy for the local area of the contamination known as The Plume.

DuPont is scheduled to begin bioremediation pilot tests in The Plume this month, according to Philip Flax, an official of the federal Environmental Protection Agency (EPA). Flax made the announcement at the April 30 meeting of the local Community Advisory Group (CAG).

Bioremediation is the process of using the metabolisms of microorganisms to remove pollutants. The process could be used in The Plume to remove the chlorinated solvents trichloroethylene (TCE) and tetrachloroethene (PCE), which have been vaporizing from the groundwater beneath the soil and entering into the homes above.

This month's pilot test would be the second that DuPont has tried in The Plume. In 2011, the company unsuccessfully tested vegetable oil to break down the TCE and PCE. This time the company will use lactate (lactic acid), a natural chemical compound produced by microorganisms that can be found in sour milk products like cottage cheese.

During the CAG meeting, Flax explained that the milk component may have a better chance of removing the solvents than the vegetable oil because it is less viscous and should move through the soil better.
