The Lincoln Memorial Reflecting Pool is treated with ‘nanobubbles’. What are they and how do they work?

As the U.S. approaches its 250th anniversary, preparations are underway in Washington D.C. to showcase its landmarks, including the Lincoln Memorial Reflecting Pool. However, recent renovations led to an unexpected algal bloom, turning the pool's water green. To combat this, officials have introduced ozone nanobubble technology. Nanobubbles are extremely small gas-filled bubbles, measuring around 100 nanometers in diameter—about one-thousandth the width of a human hair. They are created by injecting gases like ozone into water using specialized equipment, resulting in billions of nanobubbles per teaspoon. These bubbles are nearly invisible but possess unique properties, such as high internal pressure and surprising stability, which make them effective for water treatment. Their ability to remain suspended in water for extended periods allows them to dissolve more gas into the liquid, making them useful for applications like algae control.

The Lincoln Memorial Reflecting Pool, a symbol of American history and civic pride, has become the center of a growing crisis involving allegations of vandalism, mismanagement, and ecological concerns. The pool, located in Washington D.C., has been subjected to a costly and controversial renovation effort led by President Donald Trump, which has resulted in widespread public outcry and legal scrutiny. According to multiple reports, the pool—once celebrated for its pristine waters and historical significance—is now marred by algae blooms, peeling paint, and alleged acts of vandalism, prompting officials to consider draining the pool for further repairs.

The situation escalated dramatically in early June 2026, when Trump took to social media to accuse multiple individuals of damaging the pool. He claimed that “multiple individuals” had been arrested for vandalizing the structure, asserting that the damage was intentional and criminal. The president emphasized that the pool’s condition was deteriorating rapidly, necessitating urgent action. He stated that the pool would have to be at least partially drained for necessary repairs, a move that has drawn both criticism and concern from environmental groups and the public. The renovation, which was initially projected to cost around $14 million, has exceeded budget expectations, with some reports suggesting the final cost could surpass $20 million.

Central to the controversy is the painting of the pool’s bottom with a distinctive “American-flag blue” color, a design choice that Trump personally approved. However, the newly applied paint has begun to peel off, mixing with algae that has proliferated in the stagnant water. This has created a visually striking yet problematic scenario, with sections of the pool appearing as if they have been stripped bare. The algae, which has turned the water a murky green, has sparked comparisons to past maintenance failures, including a previous attempt by former President Barack Obama to improve water quality that ultimately proved unsuccessful.

Among those accused of damaging the pool is David Carter Hearn, a 67-year-old Olympic canoeist and avid cyclist. Hearn was arrested by the US Park Police after allegedly reaching into the water to examine a piece of peeling paint. He claims he was merely curious and that his actions did not constitute vandalism. Hearn described the incident as a misunderstanding, stating that he was simply trying to understand the materials used in the renovation. He also pointed out that similar behavior had occurred earlier when ABC News reporter Jonathan Karl lifted a piece of paint in a video, suggesting that the act itself might not be illegal. Hearn’s case highlights the broader debate over whether the pool’s condition is the result of deliberate vandalism or poor construction practices.

The renovation project itself has been mired in controversy from the outset. The contractor, Atlantic Industrial Coatings, a Virginia-based firm with ties to Trump, was awarded a no-bid contract, raising questions about transparency and accountability. Critics argue that the rushed nature of the project, combined with the lack of competitive bidding, has contributed to the current state of the pool. Environmental consultants have expressed concerns that the pool’s design and location—being a shallow, non-circulating body of water—create ideal conditions for algal growth. These factors, they suggest, may have played a role in the current crisis, despite Trump’s insistence that the damage is due to vandals.

In response to the growing unrest, the National Park Service has taken steps to secure the area, installing surveillance cameras and increasing security personnel. The installation of additional lighting and cameras has been accompanied by heightened police presence, including National Guard units patrolling the vicinity. These measures reflect the administration’s growing anxiety over the pool’s condition and the potential for further incidents. Meanwhile, the Department of the Interior has attempted to address the algae problem by using hydrogen peroxide to treat the water, though the effectiveness of these interventions remains uncertain.

Public reaction to the situation has been mixed. While some citizens support Trump’s efforts to restore the pool, others view the project as a misguided attempt to bolster his image through symbolic gestures. The pool’s transformation into a focal point of political discourse underscores the broader tensions between the administration and critics who question the prioritization of aesthetic improvements over practical infrastructure needs. Environmental advocates have also raised alarms about the impact of the renovation on local ecosystems, noting that the presence of dead ducks and other wildlife in the pool suggests deeper ecological concerns.

As the situation continues to unfold, the fate of the Lincoln Memorial Reflecting Pool remains uncertain. With the pool scheduled for partial draining, the focus will shift toward determining the extent of the damage and identifying the root causes of the current crisis. Whether the blame lies with vandals, contractors, or natural factors, the controversy surrounding the pool serves as a microcosm of the larger debates over governance, environmental stewardship, and the role of public figures in shaping national symbols. For now, the pool stands as a testament to both the ambitions and the limitations of political leadership in addressing complex challenges.

Security cameras, extra guards at Reflecting Pool as Trump says six arrested

Surveillance cameras and additional security measures have been deployed at the Lincoln Memorial Reflecting Pool in Washington, D.C., following claims by U.S. President Donald Trump that six individuals were arrested for vandalizing the site. The pool, part of a $16 million renovation project intended to repaint it in 'American-flag blue' for the nation's 250th anniversary, has faced issues including algal blooms and peeling paint. Trump asserts that the damage was caused by deliberate acts of vandalism using knives or razors, describing cuts spanning hundreds of feet. However, critics suggest the damage could stem from poor construction quality by contractors linked to Trump, who secured the contract without a competitive bidding process. The Trump administration faces calls for evidence supporting the vandalism claim, while the National Park Service and other relevant agencies have yet to publicly address the allegations.
