Algae Is Turning the Reflecting Pool Green. Again.

Article excerpt

The Reflecting Pool, the iconic rectangular body of water stretching between the Lincoln Memorial and Washington Monument, has turned algae-green again, this time following a $14.2 million repair project meant to restore the site. Algal blooms have plagued the pool before, but the recurrence raises questions about whether the renovation addressed the underlying conditions that fuel the growth. The pool's transformation from gleaming mirror to murky green has become a recurring embarrassment for one of Washington's most photographed landmarks, visible to millions of visitors and appearing in countless official ceremonies and celebrations.
