The National Park Service (NPS) is actively treating algae blooms in the Lincoln Memorial Reflecting Pool, which turned green shortly after a $14.6 million renovation aimed at giving it an "American flag blue" hue. The Interior Department has deployed nanobubble ozone technology and hydrogen peroxide treatments to eliminate the algae, which appeared late last week. Workers were seen applying these treatments on Tuesday, with rangers also scraping algae from the pool's bottom and siphoning contaminated water. A DOI spokesperson confirmed the hydrogen peroxide is safe for the environment and marine life. The pool's cloudy appearance is due to stirred-up algae that has not yet been fully extracted. The White House stated that the high-tech nanobubble system will be used for regular maintenance to keep the pool clear. President Trump had previously highlighted the renovation, describing the pool as "filthy" before the upgrade.
