The National Park Service continued a push Tuesday to eradicate algae from the Lincoln Memorial Reflecting Pool as tourists and locals gathered to view the green-tinged water.

The Department of Interior has deployed both a hydrogen peroxide treatment and nanobubble ozone technology, a DOI spokesperson said, to rid the pool of algae blooms that have discolored the landmark and marred the rollout of President Donald Trump's renovation project.

Algae bloomed late last week just days after the completion of the renovation, turning the pool from deep blue to green and murky. A DOI spokesperson told CNN in a statement that the algae was "residual" and came from reactivated supply lines.
