Good news.... scientists have discovered a new recipe to make cookies out of the Hanford brew.

Here's the story:

RICHLAND -- Hanford scientists are hoping that pumping enough molasses to make 88,000 batches of cookies into the ground at the nuclear reservation will be a recipe for cleanup success.

The theory is that adding a rich food supply for microbes should change the groundwater chemistry enough to convert some of the toxic chromium moving toward Columbia River into a nontoxic form.

"We're trying to find other solutions that are more innovative, more cost effective," said Mike Thompson, DOE groundwater cleanup manager.

A tanker truck of molasses, 5,500 gallons, is being mixed into a solution that's 95 percent water. This week, it's being injected into the groundwater that lies in a 20-foot layer about 85 feet below the ground near the D Reactor. It's expected to spread out to cover a diameter of about 100 feet.

"Basically, we're adding sugar water," said Mike Truex, a Pacific Northwest National Laboratory scientist.

That will overfeed the bacteria in the ground water, causing the population to explode.
