Is the Lincoln Memorial Reflecting Pool Floor Already Peeling?

The newly renovated floor of the Lincoln Memorial Reflecting Pool has begun peeling less than two weeks after work was completed, raising fresh questions about the high‑profile project.

Photos taken this week show sections of the newly applied blue coating lifting from the bottom of the pool and floating in the water, which has also turned green due to an algae bloom.

The $14 million refurbishment, completed earlier this month, was intended to transform the iconic Washington, D.C. landmark ahead of the nation's 250th anniversary celebrations. The work was carried out by Virginia-based contractor Atlantic Industrial Coatings, which was brought in as part of the high-profile overhaul of the century-old basin.

Newsweek reached out to Atlantic Industrial Coatings via email for comment.

The development comes as the Trump administration has defended the broader renovation effort, saying it is taking the steps "necessary" to ensure the capital looks "stunning" ahead of the milestone celebrations, even as scrutiny around the project intensifies. Interior Secretary Doug Burgum has been one of the public faces of the effort, touring the Reflecting Pool after it was recoated and refilled and promoting the refurbishment as part of the administration's wider push to remake Washington ahead of the July 4 celebrations.

While officials have not confirmed the cause of the failure, experts say a combination of environmental, chemical and construction factors could be behind the rapid deterioration.

On the poolside, members of the public have been filming and photographing the pool coating as it lifts, with some even collecting it from the pool.

Newsweek reached out to the Department of the Interior for comment.

Coating Failure Can Have ‘Multiple Causes’

Early assessments suggest the peeling is unlikely to be the result of a single issue.

The issue has also drawn wider political and legal scrutiny, with the administration recently moving to dismiss a lawsuit over changes to the Reflecting Pool, arguing the alterations do not cause harm-claims that critics dispute as problems continue to emerge.

The case, brought by The Cultural Landscape Foundation (TCLF) and its founding president and CEO, Charles A. Birnbaum, challenges the redesign of the historic site and raises questions about whether alterations to the Reflecting Pool complied with preservation rules governing the National Mall. The administration has argued in court filings that the changes fall within its authority and do not materially damage the site.

In court filings, government lawyers argued that TCLF no longer had a viable claim tied to the pool's "current state," while Birnbaum told Newsweek the administration had "acted in haste," leading to "predictable problems."

Critics have further pointed to the rapid appearance of algae and now peeling coating as evidence that the project may have introduced new problems, undermining assurances that the refurbishment would improve both the appearance and long-term condition of the landmark.

1. Algae Growth and Water Chemistry

The peeling has coincided with a rapid algae bloom that turned the pool green within days of refilling, complicating efforts to maintain the intended blue appearance.

Large outdoor water features like the Reflecting Pool are particularly vulnerable to algae due to warm temperatures, sunlight and nutrient‑rich water sources.

Shifts in water chemistry-especially soon after a refill-can create harsh conditions for newly applied coatings, potentially weakening their bond to the underlying surface.

There are some suggestions that the new "American flag blue" coating may itself have made the algae problem worse by changing the pool's heat dynamics. The Reflecting Pool is only around 18 to 30 inches deep, meaning sunlight absorbed at the bottom has relatively little water volume to disperse through. In practice, that allows a dark coating to act like a heat sink: it absorbs more solar radiation than a lighter or more reflective surface, converts that energy into heat at the floor-water interface, and helps warm the shallow water column more quickly.

Tim Auerhahn, chair of Aquatic Council, LLC, cautioned that identifying a single cause for the paint peeling from early footage is difficult. "Based on the videos alone, it’s impossible to determine the actual cause of the apparent delamination," he told Newsweek, adding that a range of factors including "environmental exposure" and water conditions should be considered.

Pool maintenance expert Steve Goodale told Newsweek those conditions can worsen rapidly at this scale, warning: "Once water turns green and algae sets in the plant matter growth can be prolific."

Previous reporting has highlighted how quickly the pool turned green after reopening. Christopher Lowe, senior lecturer in marine biology at Swansea University, told Newsweek that the new dark surface in a shallow sunlit pool could create "perfect conditions for algae to bloom.”

"When you combine warm temperatures, sunlight and a ready supply of nutrients, algae can establish and spread very quickly," Lowe said, noting that large open-air water features like the Reflecting Pool are especially vulnerable because they are continuously exposed to these elements.

2. Chemical Treatments

Efforts to tackle the algae bloom may also have contributed to the problem.

Workers were seen adding hydrogen peroxide to the pool as part of attempts to restore water clarity, but highly concentrated oxidizing agents such as hydrogen peroxide are known to interact with coatings and may weaken or strip paint under certain conditions.

Goodale said the effectiveness of peroxide treatment depends heavily on scale and conditions: "The amount of peroxide needed depends on not just the strength concentration of the peroxide, the size of the body of water, but also importantly the amount of algae and physical debris in the water. So I can not give a truly accurate estimate here because the amount of algae is unknown."

Auerhahn, however, urged caution in linking treatment directly to the failure of the paint. "Chemical treatment is certainly one of several factors that should be evaluated, but I am hesitant to identify water chemistry or hydrogen peroxide treatment as the cause without further testing and analysis," he said.

The use of hydrogen peroxide has itself prompted questions from observers about safety and the effectivity of chemical treatment as a solution to the algae.

3. Adhesion Problems

One of the most common causes of peeling in concrete water structures is poor adhesion between the coating and the substrate.

If the surface was not properly prepared-due to moisture, contamination or incomplete curing-the coating may not bond effectively, leading to early failure.

Auerhahn said a wide range of technical issues could be involved: "Failure could be caused by substrate penetration, surface contamination, moisture conditions during application, adhesion issues, environmental factors, mechanical damage, environmental exposure, or product selection."

He said the extent of the issue will be crucial: "The key question is whether the apparent delamination is isolated to a small specific area or is a more widespread occurrence throughout the basin.

"If it is indeed widespread, it could suggest a more systematic failure requiring further investigation."

4. Scale and Environmental Stress

The Reflecting Pool presents unique challenges compared with standard swimming pools.

Holding more water than 10 Olympic-sized pools, it is fed by the nearby Tidal Basin and subject to continuous exposure to sunlight, temperature fluctuations and organic material.

These factors combine to create a demanding environment in which coatings must withstand constant chemical, thermal and biological stress.

Auerhahn said that these cumulative stresses can affect long-term performance, noting that coatings exposed to "prolonged UV radiation, fluctuating temperatures and chemical treatment will experience environmental stresses over time."

Why Timing Matters

The speed at which the coating has begun to fail-within days rather than months or years-has raised particular concerns.

Auerhahn said the timeframe is notable if confirmed: "If the observed condition proves to be actual coating delamination, it would be unusual to see that type of failure so soon after installation. We generally expect a properly installed coating system to perform for many years before significant adhesion issues develop."

However, he added a note of caution: "It’s important not to draw broad conclusions from a single visible area. The extent of the condition and the underlying cause would need to be determined before assessing whether this represents an isolated coating defect or a broader performance concern."

The rapid deterioration has also fueled criticism, including remarks from Mary Trump, who mocked the situation as emblematic of wider issues with the project.

In a video posted on X, she criticized the administration's handling of the renovation, saying: "It appears that the governing principle of the Trump regime is don't believe your own lying eyes, you idiots," contrasting official assurances about the pool with images showing green water and ongoing cleanup efforts.

She also took aim at the cost and procurement of the project, adding: "No other president would spend $14 million of taxpayer dollars to fix something that wasn't broken just to enrich one of his cronies."

Officials, meanwhile, have sought to reassure the public, with the administration comparing the cleanup effort to major operations as it works to address the problems.

In a social media post promoting the cleanup, the Interior Department said the Reflecting Pool was being restored using advanced technology and declared the water "crystal clear." It added that workers were removing algae from the bottom of the pool "just like the destroyed Iranian Navy resting on the bottom of the Persian Gulf," an analogy that drew attention for linking routine maintenance work to a recent military conflict.
