The Reflecting Pool Appears to Be Rejecting Its Makeover

As National Park Service crews try to clean the algae that turned the water bright green, another problem has developed: The “American flag blue” coating is coming off.

First, the new paint job appeared uneven. Then, an algae bloom turned the water an acid green. Now, large chunks of coating are peeling off the basin, creating islands of “American flag blue” alongside patches of pea green in a dark, murky soup. ... The Reflecting Pool at the Lincoln Memorial seems to be rejecting its makeover.

President Trump’s project to reseal and paint the concrete basin of the century-old pool that stretches between the Washington Monument and the Lincoln Memorial in Washington was finished nearly two weeks ago, in time for the country’s 250th birthday, as he demanded. But it has been nothing but a headache for the administration since.

The Interior Department said on social media this week that its workers had “killed the algae” that had been hastened on by the heat and humidity. The water, it boasted, was now “crystal clear.” The posts were accompanied by images of the Washington Monument reflected in deep blue waters, an apparent rebuttal to criticism from experts who say the pool’s waters will not appear a brilliant blue until the government tackles the underlying problems that have stumped previous presidential administrations.
