The Lincoln Memorial Reflecting Pool Renovation
A Trump-championed project faced legal challenges, cost disputes, and an immediate return of algae after a rushed one-month overhaul.
Project Overview and Timeline
The Lincoln Memorial Reflecting Pool was drained in late April 2026 for a renovation championed by President Donald Trump. The work involved resurfacing, repainting, and installing new filtration systems.
President Trump initially estimated the project would take one to two weeks and cost between $1.5 million and $2 million. The work was completed on May 20, 2026—roughly one month later.
"The pool was filthy dirty and leaked like a sieve." — President Donald Trump
The pool was resurfaced with a material the President described as "American flag blue." Trump stated he initially considered turquoise but was convinced by a contractor to choose the darker shade. The Department of the Interior described the finished coat as "a very dark blue" with "low chroma," consistent with the pool's historic character.
Visitors on May 22 reported the color difference was not immediately noticeable, with descriptions ranging from grey to black. Some observed the water appeared cleaner than before.
Contract and Cost
The renovation contract was awarded to Atlantic Industrial Coatings LLC, a Virginia firm, without competitive bidding. The administration cited urgency to complete work before the nation's 250th anniversary celebrations on July 4, 2026.
Federal spending records reveal a significant cost escalation:
- Initial contract: Nearly $7 million (April 3, 2025)
- Supplemental agreement: $6.2 million (May 8, 2025)
- Total contract value: $13.1 million
- Reported final cost: $14.2 million
President Trump stated he did not know the contractor and had never used the company before. The Department of the Interior explained:
"The contract price reflects the effort necessary to expedite the timeline of completing the leak prevention coating project—more people, more materials, more equipment and longer hours ahead of our 250th."
The contract included painting the pool floor, installation of an ozone nanobubbler filtration system, a dedicated maintenance crew, sealing crevices, and removing 12 truckloads of garbage.
Background on Pool Conditions
The reflecting pool opened in 1923. A major renovation from 2010 to 2012—funded by $34 million from an Obama-era stimulus package—addressed water quality and watertightness issues.
However, that project installed the wrong size water system pipes, according to a Department of the Interior budget report for fiscal year 2023. The incorrect pipes caused continuous breaks and failures due to soil pressure.
The department reported that the pool lost significant water, requiring 71 million gallons of additional water in 2019 alone, with water costs exceeding $1 million that year.
Legal Challenge
The Cultural Landscape Foundation (TCLF) filed a lawsuit on May 11, 2026, in U.S. District Court for the District of Columbia against the National Park Service, the Department of the Interior, and Interior Secretary Doug Burgum.
The lawsuit sought to halt the project, arguing the Trump administration failed to conduct a federally required review under the National Historic Preservation Act, including public notification and input from other federal agencies. No environmental impact assessment was issued.
The case was assigned to Judge Carl Nichols, but as of the project's completion, no ruling had been issued.
"The reflecting pool should not be viewed in isolation; it is part of the larger ensemble of designed landscapes that comprise the National Mall. A blue-tinted basin is more appropriate to a resort or theme park." — Charles A. Birnbaum, TCLF President and CEO
Birnbaum previously served 15 years as coordinator of the Historic Landscape Initiative for the National Park Service before founding TCLF in 2008.
The Department of the Interior responded that the blue color "will enhance the visitor experience" and that the National Park Service "chose the best company to expedite the repair of the iconic Reflecting Pool ahead of our 250 celebrations."
Algae Return
Days after the renovation was completed, algae returned, turning the water green. National Park Service workers were observed cleaning algae with hand tools and using skimmers.
The Department of the Interior stated that the administration installed "nanobubbler technology" and hydrogen peroxide treatment to address the algae. Spokesperson Katie Martin stated that the nanobubblers destroyed the algae bloom and remaining algae was being vacuumed up.
The department attributed the algae resurgence to residual algae from supply lines connected to the Tidal Basin and described it as part of the normal startup process.
Environmental scientists noted that shallow manmade water bodies are prone to algal growth due to warm temperatures, sunlight, and nutrients from animal waste and fertilizer runoff. Algae has been an ongoing issue in the pool since it opened in 1922.
Aerial photos from early June showed signs of algae dissipating from the sides but remaining clumped in the center.
Presidential Statements
President Trump posted multiple times on Truth Social about the project. In a June 5 social media post, he stated the renovation used:
"Highly sophisticated material, industrial strength, that could last for 100 years."
He also wrote:
"This is not just a paint job, like lowlife 'reporter,' David Fahrenthold, of the NYT so inaccurately and maliciously stated, it is a deeply complicated work of smart and beautiful construction."
Trump accused The New York Times of "trying to justify Obama and Biden's expensively botched attempt at fixing the long broken, unsightly, and unsanitary Reflecting Pool."
Related Projects
The reflecting pool renovation was one of several Washington, D.C., beautification projects undertaken by the Trump administration. Other projects include:
- Installation of new statues
- Restoration of park fountains, including at Meridian Hill Park
- Cleaning of graffiti
- Construction of an Ultimate Fighting Championship Octagon on the South Lawn and Ellipse
- A proposed "promenade" connecting the Lincoln Memorial to the Potomac River
National Guard troops have been deployed for this work, with numbers set to double ahead of July 4th events.
Public Reactions
Visitors expressed mixed reactions to the renovation.
"I'm just happy it's not that bright blue that we saw the first days... if it stays like this, it's fine." — Luisa Córdoba, D.C. resident
"It doesn't look blue... it's more grey." — Edgar Sadsad, Maryland resident
"It's kind of sad where our tax dollars are going. I mean, it was fine before." — Samantha Sorokin, Arlington, Va. resident
Some expressed disappointment that renovations occurred during peak tourist season, while others welcomed the changes, citing the pool's previous appearance. Several visitors stated they did not mind the green color or considered the renovation a waste of funds.
