Green In Bloom

Well, they wanted D.C. to go green:

Less than a month after reopening, the Lincoln Memorial Reflecting Pool is full of algae, a sea of green overshadowing the nearly two-year, $34 million renovation of the famous site.

The National Park Service anticipated a “break-in period” in which problems would need to be addressed, spokeswoman Carol Johnson said, but no one expected the amount of algae that is there now.

While the pool took its water from the city’s drinking system, the reconstruction allows it to take water from the Tidal Basin, saving the city 32 million gallons of water a year.

But because the pool is a smaller and shallower water source, the algae cells bloom more easily there.

“This is a direct consequence of the fact that this is a green project,” Johnson said. “The conditions are pretty good for algae, once it gets in there.”
