Reflecting Pool Algae Bloom Spurs Chemical Response After $14 Million Trump Renovation
6/17/2026, 2:37:42 AM
Background
The Lincoln Memorial Reflecting Pool, long plagued by algae, underwent a $14 million renovation in 2026 that repainted its surface “American Flag Blue.”
Key Figures
President Donald Trump launched the project; the Interior Department (spokesperson Katie Martin) and the National Park Service oversaw execution; Atlantic Industrial Coatings performed the painting; pool expert Steve Goodale and the Cultural Landscape Foundation offered commentary.
Timeline
April 2026: renovation announced. May 7: painting inspected. Early June: pool refilled. June 15-16: algae bloom; crews applied 12 % hydrogen peroxide. June 16 onward: nanobubble ozone system activated. Fall 2026: pipe repairs scheduled.
Data
The project cost $14 million (contract $14.2 million). Nanobubble upgrade $1.7 million. Pool length ?2,000 ft. Hydrogen peroxide used at 12 % concentration. Circulation ?4 million gallons per three days.
Official Statements
Interior Department spokesperson Katie Martin said the National Park Service now maintains the pool and is using advanced nanobubble ozone technology to kill algae and pathogens, describing hydrogen peroxide as a milder treatment than chlorine with no marine harm. The NPS called the bloom a normal startup issue. The department thanked Trump for “fixing the Reflecting Pool for good.”
Criticism
Environmental groups warned that 12 % hydrogen peroxide can irritate lungs, burn skin, and threaten ducks. Goodale said the darker paint raises water temperature, accelerating algae. Online critics called the chemical response “stupid” and questioned the $14 million cost versus inadequate filtration.
On-the-Ground
A resident called the water “a mess” and “the greenest I’ve ever seen.” Ducks were seen swimming amid the algae.
Conflicting Reports
The bloom is blamed on residual supply-line algae (Interior), normal startup (NPS), and heat from darker paint (Goodale). The Interior Department says hydrogen peroxide is safe, while CDC warnings note health risks. Cost and timeline estimates also diverge from Trump’s $1.5-2 million, two-week promise.
Verbatim Quotes
- “I think it’s a mess. I’ve never seen it this green before,” — Local resident
- “Unlike under Obama and Biden, the National Park Service is actually maintaining the beautifully completed Reflecting Pool,” — Katie Martin, Interior Department spokesperson
- “If we change nothing else except the color, and we go from a lighter color to a darker color, absolutely you’re going to have more prolific algae growth,” — Steve Goodale, pool specialist
- “Do you have any idea how much hydrogen peroxide you’d need to kill the algae in the Reflecting Pool? It’s not a huge deal, obviously, but this is another example of how absolutely stupid the people in charge right now are.” — Online critic (Twitter)
What’s Next
Fall pipe repairs will proceed; the Interior Department will monitor nanobubble and peroxide efficacy, while watchdogs continue oversight.
