Trump’s Vision for Lincoln Memorial Reflecting Pool Faces Algae Challenges

The Lincoln Memorial Reflecting Pool, redesigned under President Donald Trump with an ‘American flag blue’ bottom, has encountered a challenge with an algae-induced chartreuse hue. The issue emerged shortly after a renovation that exceeded $14 million. The Washington Monument is now seen reflected in the pool’s waters, yet Trump’s goal of a striking azure between the landmarks confronts the realities of chemistry and biology known to pool owners.

This challenge arises from the structure’s enormous scale, which surpasses ten Olympic pools, and its water source, the often-unclean Tidal Basin. Since the pool’s dedication over a century ago, algae has been a persistent problem. Trump targeted this issue as part of a wider effort to enhance Washington’s aesthetics before the United States’ 250th anniversary. Initiated in April, the project followed complaints from a German visitor who described the pool as unappealing.

To tackle the algae, teams from the National Park Service and contractors deployed chemicals and innovative ozone nanobubbles. These nanobubbles serve as a water purification method avoiding harsh chemicals. Additionally, workers employed a vacuum system to remove algae, revealing clean areas of American Flag Blue paint amidst vast stretches of algae, reminiscent of carpet vacuuming patterns.

The newly painted dark bottom of the pool presents another challenge. ‘The new paint elevates the water temperature, promoting algae growth,’ stated Cochise Wanzer II, president of a Virginia pool service.

The cleaning strategy involves utilizing ozone nanobubbles, hydrogen peroxide, and other mild treatments. The Park Service assures that these methods have no adverse effects on marine life or the environment. Water from the pool was temporarily removed during the cleaning process. A contractor, rolling up his pants, demonstrated the treatment by placing an ozone nanobubble tube into the pool.

Nearby, tourists like Rick and Ariana Pettit from Las Vegas observed the cleaning activity while enjoying the historic site. They wore patriotic attire, noting improvements in the pool’s appearance. Wanzer suggested that a complete drainage might be necessary for a long-term algae-free condition: ‘Drain it, clean it thoroughly, and maintain fresh water from the start.’
