Green algae return to reflecting pool days into Trump’s renovation
Crews are using hydrogen peroxide and nanobubbler technology to clear the bloom after a $14.2 million renovation meant to keep the pool blue.
- Just days after a $14.2 million renovation, the Lincoln Memorial Reflecting Pool became overrun with algae, threatening preparations for the nation's 250th anniversary celebration on July 4.

- Algae thrives in hot weather but dissipates in cooler months, experts explained, meaning July temperatures in the upper 80s and 90s may complicate efforts to restore the pool's blue appearance before Independence Day.
