Why the Reflecting Pool Is Full of Algae After Trump's Renovation

Why the Reflecting Pool Is Full of Algae After Trump's Renovation Warm weather has fueled a bloom that US National Park Service workers are trying to kill using everything from hydrogen peroxide to nanobubbles ahead of July 4 celebrations. On Wednesday morning, workers poured hydrogen peroxide into the Lincoln Memorial Reflecting Pool in Washington, DC. The treatment is the latest attempt by the Interior Department to control an algae bloom that has turned the pool bright green, despite President Donald Trump's costly renovation to make it "American flag blue" in time for the nation's 250th anniversary . Hot temperatures and climate change are among the risk factors that could be driving the outbreak. The Trump administration spent more than $14 million to update the pool ahead of celebrations across the US capital .
