The $34 million reconstruction of the Reflecting Pool in front of the Lincoln Memorial was completed a few weeks ago, but green algae is now visible on the surface of the water.
The pool now has a new water circulating system, with its water pumped from the Tidal Basin, filtered, and treated prior to entering the reconstructed pool.
This new system continuously circulates and treats the water using ozonation, a natural water treatment process requiring no chemicals.
Many visitors are surprised to see the algae, but the National Park Service said situations like this were expected and engineers are making necessary adjustments as work crews skim the pool manually to help the filtering process along.
