Trump’s pool makeover backfires as Lincoln Memorial pool runs green

A renovation ordered by Trump left the Lincoln Memorial Reflecting Pool green with algae, despite plans to keep it crystal clear with nanobubble ozone technology and hydrogen peroxide. The project’s cost ballooned from an initial $1.5–2 million to about $14.2 million, and officials warn algae blooms are a persistent challenge in the shallow, warm pool as the National Park Service manages maintenance backlogs ahead of July 4.
