As the Lincoln Reflecting Pool turned green with algae, officials are now using chemicals to fix it.

The Washington Monument is once again visible in the refilled pool, but Trump's vision of an azure expanse between the D.C. landmarks has been complicated by the harsh realities of chemistry and biology known to any backyard pool owner.

Workers are now deploying hydrogen peroxide in a bid to bring an algal bloom under control in the Lincoln Memorial Reflecting pool. The cause of the pool turning green is an algal bloom, which has happened following the renovations of the historical landmark.

The Trump administration spent about $14.2 million on renovations to the Reflecting Pool, including painting it “American Flag Blue.”

The National Park Service is deploying hydrogen peroxide in the Lincoln Memorial Reflecting Pool to combat algae growth, according to a Department of the Interior (DOI) spokesperson. This effort follows the Trump administration’s controversial $13.

The water in Washington DC's Lincoln Memorial Reflecting Pool has turned green, and National Park Service officials are turning to drastic measures.

Trump can't be happy that tourists can't see his handpicked "American flag blue" paint.

In case you were alarmed by the images of ducklings floating around in the now-green Reflecting Pool, which the Trump administration has been dumping jugs of hydrogen peroxide into to try to contain an algal outbreak, they're probably fine, says a D.C. wildlife group.
