Reflecting Pool Turns Green

The Lincoln Memorial Reflecting Pool turned bright green from an algae bloom just days after the Trump administration completed a costly renovation meant to give it an “American flag blue” bottom ahead of the nation’s 250th anniversary. Crews responded by pouring hydrogen peroxide into the 6.5 million-gallon pool and using bubbling equipment in an effort to beat back a problem that has plagued the landmark for decades. The project, reported at more than $14 million, drew fresh scrutiny because President Donald Trump had publicly promoted the refurbishment as a transformation of what he called a dirty and leaking site. Officials face both practical and political pressure as heat and persistent algae undercut the newly finished work.
